LESSERt* AND RICHARD P. BLAKEMORE Department of Microbiology, University of New Hampshire, Durham, New Hampshire 03824 Received 8 November 1989/Accepted 3 June 1990 A gram-negative, marine, facultatively anaerobic bacterial isolate designated strain AS-1 was isolated from the subcuticular space of the brittle star, Amphipholis squamata. Its sensitivity to 0/129 and novobiocin, overall morphology, and biochemical characteristics and the moles percent guanine-plus-cytosine composition of its DNA (42.9 to 44.4) suggest that this isolate should be placed in the genus Vibrio. Strain AS-1 was not isolated from ambient seawater and is distinct from described Vibrio species. This symbiotic bacterium may assist its host as one of several mechanisms of nutrient acquisition during the brooding of developing embryos.

Mollusks and a Crustacean from Early Oligocene Methane-Seep Deposits in the Talara Basin, Northern Peru
Mollusks and a crustacean from early Oligocene methane-seep deposits in the Talara Basin, northern Peru STEFFEN KIEL, FRIDA HYBERTSEN, MATÚŠ HYŽNÝ, and ADIËL A. KLOMPMAKER Kiel, S., Hybertsen, F., Hyžný, M., and Klompmaker, A.A. 2020. Mollusks and a crustacean from early Oligocene methane- seep deposits in the Talara Basin, northern Peru. Acta Palaeontologica Polonica 65 (1): 109–138. A total of 25 species of mollusks and crustaceans are reported from Oligocene seep deposits in the Talara Basin in north- ern Peru. Among these, 12 are identified to the species-level, including one new genus, six new species, and three new combinations. Pseudophopsis is introduced for medium-sized, elongate-oval kalenterid bivalves with a strong hinge plate and largely reduced hinge teeth, rough surface sculpture and lacking a pallial sinus. The new species include two bivalves, three gastropods, and one decapod crustacean: the protobranch bivalve Neilo altamirano and the vesicomyid bivalve Pleurophopsis talarensis; among the gastropods, the pyropeltid Pyropelta seca, the provannid Provanna pelada, and the hokkaidoconchid Ascheria salina; the new crustacean is the callianassid Eucalliax capsulasetaea. New combina- tions include the bivalves Conchocele tessaria, Lucinoma zapotalensis, and Pseudophopsis peruviana. Two species are shared with late Eocene to Oligocene seep faunas in Washington state, USA: Provanna antiqua and Colus sekiuensis; the Talara Basin fauna shares only genera, but no species with Oligocene seep fauna in other regions. Further noteworthy aspects of the molluscan fauna include the remarkable diversity of four limpet species, the oldest record of the cocculinid Coccopigya, and the youngest record of the largely seep-restricted genus Ascheria. -

This study uses variation at 12 allozyme loci, phylogenetic analyses of 600 bp of a COI (cyto- chrome c oxidase subunit I) mtDNA fragment and morphometric comparisons to determine whether 15 populations are conspeciWc, and, if not, to elucidate their evolutionary relationships. Molecular evidence suggested that the most easterly population, collected from the Tsitsikamma Forest, was representative of a yet undescribed species. Patterns of diVerentiation and evolutionary relation- ships among the remaining populations were unrelated to geographic proximity or drainage system. Patterns of isolation by distance were also absent. An apparent disparity among the extent of genetic diVerentiation was also revealed by the two molecular marker sets. Mitochondrial sequence divergences among individuals were comparable to currently recognized intraspeciWc divergences. Sur- prisingly, nuclear markers revealed more extensive diVerentiation, more characteristic of interspeciWc divergences. -

Abstract: Despite the important effort of knowing the Ophiuroidea diversity in the Mexican Pacific, some mis- takes in the taxonomic nomenclature have pervaded through time. In order to clarify the latter, a checklist based on literature review of brittle stars from the Mexican Pacific is provided. We reviewed a total of 105 references that in total summarized 125 species of brittle stars from the Mexican Pacific (112) and the Gulf of California (97), belonging to two orders, 16 families and 50 genera. These records are higher than those reported on previ- ous studies carried out in the area. -

It is distinguished from its congeners in having: four or five paired papillae and unpaired papillae present along entire dorsal radii (four to seven papillae on each radius), with wide separation between second and third paired papillae; maximum length of Elpidia-type ossicles in dorsal body wall exceeds 1000 µm; axis diameter of dorsal Elpidia-type ossicles less than 40 µm; tentacle Elpidia-type ossicles with arched axis and shortened, occasionally completely reduced arms and apophyses. Purple pigmentation spots composed of small purple particles on both dorsal and ventral body wall. This is the second species of Elpidia Théel, 1876 from Japanese abyssal depths. The diagnosis of the genus Elpidia is modified to distin- guish from all other elpidiid genera. -
Comparative Anatomy of Four Primitive Muricacean Gastropods: Implications for Trophonine Phylogeny
^/ -S/ COMPARATIVE ANATOMY OF FOUR PRIMITIVE MURICACEAN GASTROPODS: IMPLICATIONS FOR TROPHONINE PHYLOGENY M. G. HARASEWYCH DEPARTMENT OF INVERTEBRATE ZOOLOGY NATIONAL MUSEUM OF NATURAL HISTORY SMITHSONIAN INSTITUTION WASHINGTON, D.C. 20560, U.S.A. ABSTRACT The main features of the shell, head-foot, palliai complex, alimentary and reproductive systems of Trophon geversianus (Pallas), Boreotrophon aculeatus (Watson), Paziella pazi (Crosse), and Nucella lamellosa (Gmelin) are described, and phonetic and cladistic analyses based on subsets of these data presented. Similarities in shell morphology revealed by phenetic studies are interpreted as being due to convergence, and are indicative of similar habitats rather than of close phylogenetic relationships. Convergences are also noted in radular and stomach characters. Cladistic analyses of anatomical data support the following conclusions: 1 ) Thaididae are a primitive and ancient family of muricaceans forming a clade equal in taxonomic rank with Muncidae; 2) Within Muricidae, P. pazi more closely resembles the ancestral muricid phenotype than any trophonine; 3) Trophoninae comprise a comparatively recent monophyletic group with differences due to a subsequent austral adaptive radiation. The Muricidae are considered to be the most primitive and D'Attilio, 1976:13) a personal communication from E. H. family within Neogastropoda according to most (Thiele, Vokes "it appears likely that the most northern trophons are 1929; Wenz, 1941; Taylor and Sohl, 1962; Boss, 1982) but derived from the Paziella-Poiheha line, and that the several not all (Golikov and Starobogatov, 1975) recent classifica- austral forms that are unquestionably "trophonine" are prob- tions. Of the five subfamilies of Muricidae, the Trophoninae, ably derived from the Thaididae". proposed by Cossmann (1903) on the basis of shell and Thus, according to most published work, the Tropho- opercular characters to include a number of boreal and ninae are in a position to shed light on the systematics and austral species, are the most poorly understood.
