ABSTRACT

Thirteen species of columbellid gastropods belonging to six genera are descnbed and figured. Two forms have been identified by means of

"open nomenclature" thus leaving a total of I 1 positively identified species. Three species, Colunihella lopczana and Paramelana iDominilana) topezana. both from the late early to early Middle Miocene Baitoa Formation of the Lopez section on Rio Yaque del Norte, and Nilidella caimitana from the Late Miocene Cercado Formation of the Rio Cana section, and one subgenus, Paramelana (Dommitanal. are descnbed as new.

Although the available material is not rich, the stratigraphic occurrences of these species are discussed. Only two species are well represented; three are moderately well represented, and the remaining species are represented by five or fewer specimens and thus must be considered rare,

A total of 13 columbellid species belonging to six La Barranca on Rio Yaque del Norte (Text-fig. 5): genera is discussed in this paper. Two forms have been Eurypyrene eurynot um (Woodring, 1928) identified by means of open nomenclature (Richter, Metulella fusiformis Gabb, 1873a 1943, 1948; Matthews, 1973; Komicker, 1979; Bengs- Metulella venusta (G.

As pointed out by Jung and Petit (1990, Arroyo Zalaya section (Saunders et al., 1986, text-fig. p. 88) the species are not continuously present through 36): a given sequence of sediments, rather their occurrences Metulella fusiformis Gabb. 1873a are spotty. Several species occur only in one of the sections considered herein; others have been found in Rio Amina section (Text-fig. 9): more than one section. The distribution of species in Metulella venusta (G. B. Sowerby II. 1850) the various sections is as follows: As found by Jung and Petit (1990, p. 88) for can- Rio Gurabo section (Text-fig. 2): cellariids, the distributional patterns of the columbellid Columbella submercatoria Olssen, 1 922 species discussed herein reflect a considerable degree Nitidella cibaoica (Maury, 1917a) of stratigraphic restriction. Seven of the 1 1 positively Metulella venusla (G. B. Sowerby II, 1850) identified species, i.e.. more than 60% of the discussed Rio Cana section (Text-fig. 3): fauna, have been found in single sections only. This is Parametaria islahispaniolae (Maury, 1917a) a large percentage considering that the sediments of all Nitidella cibaoica (Maury, 1 9 1 7a) the sections in which these species occur are of similar Nitidella caimitana, n. sp. age (late Miocene to early Pliocene) with the exception Metulella venusta (G. B, Sowerby II, 1850) of the Lopez section which is of late early to early Lopez section of Rio Yaque del Norte (Text-fig. 4): middle Miocene age (Saunders et al.. 1986, p. 30).

The remaining four species which are restricted to single sections are distributed as follows: — Columbella submercatoria Olsson, 1922 has been found at two localities (NMB 1 59 1 0, 1 59 1 2) in the Rio .< -v.-^ Gurabo section: upper part of Cercado Formation (late Miocene). See Text-figure 2. — Columbella lopezana, n. sp. is recorded from four localities (NMB 16935, 17288, 17289, 17290) in the Lopez section on Rio Yaque del Norte: Baitoa For- mation (late early to early middle Miocene).

— Parametaria lopezana, n. sp. is recorded from three localities (NMB 16936, TU 1363, TU 1364) in the Lopez section on Rio Yaque del Norte: Baitoa For- mation (late early to early middle Miocene). See Text- figure 4.

— Conella perplexabilis (Maury, 1 9 1 7a) is known from a number of localities in the Rio Mao section: Cercado Formation (late Miocene). See Text-figures 7 and 8. In addition to the seven species with restricted dis- tribution as pointed out above, there are four species which occur in more than one section. The most wide- ^"zr spread species is Metulella venusta (G. B. Sowerby H,

1 850) which has been found in beds cropping out along Rio Cana, Rio Gurabo, Rio Mao, Rio Amina, and Rio

Yaque del Norte (Text-figs. 2, 3, 5, 9). It is followed by Parametaria islahispaniolae (Maury, 191 7a) which is known from a number of localities in the sections of Rio Cana and Rio Mao (Text-figs. 3, 6, 7, 8).

Out of the 1 1 positively identified species eight are known only from the Dominican Republic. This fact points to a remarkable endemism. The remaining three species are also known from other countries. They are:

— Columbella submercatoria Olsson, 1922 is recorded from the late Miocene Cercado Formation of the Do- minican Republic, but is also known from the early Pliocene Bowden Formation ofJamaica and from beds of late Miocene or early Pliocene age in Costa Rica.

Type species (by nwnotypyl.— Voliita mercatoria Linnc, 1758, p. 730. Recent. West Indies. Diagnosis. — ShsW of small to medium size (10-30 mm in height), stout, and solid. Protoconch consists of about one and a half smooth volutions. Number of teleoconch whorls usually six to seven. Profile of spire whorls almost straight, slightly convex, or somewhat shouldered. Body whorl large, evenly rounded or shouldered. Sculpture consists of more or less accen-

tuated spiral cords, or it is lacking entirely. Axial sculp- tural element subordinate or missing. Aperture sig- moid and narrow. Outer lip usually with prominent denticles on its inner surface. Columella with denticles. Anterior canal short, posterior canal inconspicuous.

on one of the figured specimens (PI. 3, figs. 7-9). Comparisons. — As pointed out under C. suhmer-

catoha, C. rusticoides Heilprin ( 1 887. p. 8 1 . fig. 9) was originally described from the Caloosahatchee Forma-

tion of Florida, but is still living in the Recent fauna.

C. aff. rusticoides is similar in degree of slenderness to

C. rusticoides. but its later whorls are evenly convex and not shouldered. Its spiral sculpture is more prom- inent that that of C rusticoides. Four recent specimens of C. rusticoides from Key Biscayne, Florida are at

hand for comparison. Although all of them are some- what worn, one specimen shows inconspicuous, or- thocline riblets on the early teleoconch whorls and in the respect is similar to the figured specimens of C. aff. rusticoides (PI. 3, figs. 7-9). C. aff. rusticoides is some- what smaller than C. platynema Woodring (1928, p. 271, pi. 16, fig. 10) from the early Pliocene Bowden Formation of Jamaica. The description of C. platy- nema was based on the holotype only, a specimen with strongly worn spire whorls. It is refigured here (PI. 3, figs. 1-3). It is therefore not known whether C. pla- tynema has any axial sculpture on the early spire whorls as does C. aff. rusticoides. The worn spire whorls of C platynema give the (probably wrong) impression that its spire is lower than that of C. aff. rusticoides. The Dominican species mainly differs from C. platynema by its considerably finer and less prominent spiral sculpture.

PREPARATION OF MANUSCRIPTS

Bulletins of American Paleontology usually comprises two or more sep- arate papers in two volumes each year. The series is a publication outlet for significant, longer paleontological monographs (i.e.. more than approximately 50 printed pages), for which high quality photographic illustrations and the large quarto format are required.

Submissions are welcome from any author, regardless of institutional or organizational affiliation. Authors must, however, be members of the Paleonto- logical Research Institution at time of publication; annual membership is currently US$20.00. Publication costs of the Bulletins are heavily subsidized by the Insti- tution, but authors are currently required to pay illustration charges at a rate of $120.00 per plate and $35.00 per text-figure.

Manuscripts must be typewritten, and double-spaced throughout (including direct quotations, tables and references). All manuscripts should contain a table of contents, lists of text-figures and/or tables, and a short, informative abstract that includes names of all new taxa. Format should follow that of recent numbers in the series. All measurements must be given in the metric system, alone or in addition to their English system equivalents. The maximum dimensions for pho- tographic plates are 178 mm x 229 mm (7 inches x 9 inches; outlined on this page). Single-page text-figures should be drafted for reproduction as single column (82 mm; 3'/4 inches) or full page (178 mm; 7 inches) width, but arrangements can be made to publish text-figures that must be larger.

Authors must provide three (3) printed copies of the text and accompanying illustrative material. Authors are 5rra«g/v encouraged to prepare their manuscripts on word processors, as this considerably expedites publication. On initial sub- mission, however, only printed copies of the manuscript should be sent; the disk copy should be retained so that revisions can be made after the review process. The text and line-drawings may be reproduced xerographically, but glossy prints at publication size must be supplied for all half-tone illustrations and photographic plates. These prints should be identified clearly on the back.

Referenced publication titles must he spelled out in their entirety. Refer to a recent number of the Bulletins for details of reference format. Citations of illus- trations within the text bear initial capitals (e.g.. Plate, Text-figure), but citations of illustrations in other works appear in lower-case letters {e.g.. plate, text-figure).

Format of systematic descriptions should follow that in any recent number of the Bulletins.

Original plate photomounts should have oversize cardboard backing and strong tracing paper overlays. These photomounts should be retained by the author until the manuscript has been formally accepted for publication. The approximate position of each text-figure in the text should be indicated. Explanations of plates and text-figures should follow the References Cited. DUE
