These be tinctly thickenings may single or double, and in some species may be beaded.

Spiral thickenings and lamellae channels may additionally provide to help align and support the free retractor muscles, principally the columellar muscle which supports the shell above the head-foot of the snail this crawling (Paul, 1983); is particularly important in groups as the Urocoptidae with elongate shells. In addition these modifications of to the columella, at least one species of urocoptid a device. This device possesses closing urocoptid closing (= UCD) was initially observed G. H. of by Clapp Pittsburgh, Pennsylvania, but a description was first published by Pilsbry (1903: 97-98, pi. 1 figs 14-15) for the Jamaican Mychostoma album (C. B. Adams, occidentalis 1849) var. Pilsbry, 1903, for which the type locality is the Great Valley estate, 124 BASTERIA, Vol. 66, No. 4-6, 2002 Hanover, and var. minima Pilsbry, 1903, from Swift River. Pilsbry stated that the UCD resembles the clausiliumof the Clausiliidae; he describedit as a tongue-shaped, whitish process continuous with the solid axis of the shell, situated in the fifth whorl from the base. Paul (1983: fig. 4B, C [our figs 2, 3]) also illustrated the UCD, which he found in only a single population. He referred this population to a complex comprising the dex- tral forms ofMychostoma, which includes M. album, but for which he considered the epi- thet alabastrina L. Pfeiffer, 1845 (fig. 1) to have priority. This UCD was situated in whorls 4-5 where, in this species, the columella has become markedly thickened. 1-3. alabastrina unknown loca- Figs Mychostoma (L.

The small numberof alcohol-preserved shells were dissected. UCDs were recorded only in M. alabastrina. A total of 14 lots ofM. alabastrina, all dry, were examined; of a total of 114 individual shells, 51 (45%) contained the UCD. In all cases the UCD occupied the 5th of 6th whorl. Pilsbry (1903: 97-98) stated that the UCD becomes flexible when wet, though it is not sufficiently large to occlude the entire cavi- ty of the shell whorl. We were able to confirm the first part of this statement, but observed that when moistened the UCD expanded slightly, the wrinkles on its surface disappeared, and it was in fact able to occlude the whole cavity. Pilsbry also described the made of "conchiolin covered unconsolidated structure as being with an layer of lime crystals"; again, the first part of the statement appears to be true, but the crystals are clearly situated within the conchiolin matrix ofthe device.

The function of the UCD is therefore most probably protec- uncertain tive as it would tendto oppose any entry from the aperture direction. It is why the UCD is missing in slightly more than halfthe specimens that were investigated, but post-mortem loss seems the most likely explanation although there was no attachment scar visible on the columella. It is unlikely that this peculiar device would have a simple, single-gene background. There is no obvious homologue structure known from closely related species. Therefore, its evolutionary origin is unclear. REFERENCES of the terrestrial shells. GITTENBERGER, E., 1996. Adaptations aperture in gastropod-pulmonate Netherlands Journal ofZoology 46: 191-205.

Here we focus on an orbweaver spider genus Cyrtognatha Accepted: 1 November 2018 (Tetragnathidae) from the Caribbean, with the aims to reconstruct its evolutionary history, examine Published: xx xx xxxx its biogeographic history in the archipelago, and to estimate the timing and route of Caribbean colonization. Specifcally, we test if Cyrtognatha biogeographic history is consistent with an ancient vicariant scenario (the GAARlandia landbridge hypothesis) or overwater dispersal. We reconstructed a species level phylogeny based on one mitochondrial (COI) and one nuclear (28S) marker. We then used this topology to constrain a time-calibrated mtDNA phylogeny, for subsequent biogeographical analyses in BioGeoBEARS of over 100 originally sampled Cyrtognatha individuals, using models with and without a founder event parameter. Our results suggest a radiation of Caribbean Cyrtognatha, containing 11 to 14 species that are exclusively single island endemics. Although biogeographic reconstructions cannot refute a vicariant origin of the Caribbean clade, possibly an artifact of sparse outgroup availability, they indicate timing of colonization that is much too recent for GAARlandia to have played a role. Instead, an overwater colonization to the Caribbean in mid-Miocene better explains the data. From Hispaniola, Cyrtognatha subsequently dispersed to, and diversifed on, the other islands of the Greater, and Lesser Antilles. Within the constraints of our island system and data, a model that omits the founder event parameter from biogeographic analysis is less suitable than the equivalent model with a founder event.

A key mission of this facility is to provide a research and learning experience in the Chihuahuan Desert. We hope that this manual will assist you in planning your research and learning activities. You will probably be given a short lecture by the station Director upon entering the station. Please pay attention as IMRS is not without potential hazards and some long-term research projects are underway that could be disturbed if one is careless. Indio Mountains Research Station came into being as a result of the generosity of a benefactor and the far-sighted vision of former UTEP President Haskell Monroe.

ZooKeys 614: 27–49. doi: 10.3897/zookeys.614.8807 Abstract We describe a new stylommatophoran land snail of the family Partulidae from Palau. The new species has a combination of morphological and ecological characters that do not allow its placement in any existing partulid genus, so we describe a new genus for it. The new genus is characterized by a large (18–23 mm) obese-pupoid shell; smooth protoconch; teleoconch with weak and inconsistent, progressively stronger, striae; last half of body whorl not extending beyond the penultimate whorl; widely expanded and reflexed peristome; relatively long penis, with longitudinal pilasters that fuse apically into a fleshy ridge that divides the main chamber from a small apical chamber; and vas deferens entering and penial-retractor muscle at- taching at the apex of the penis.

E-mail: [email protected] 4Corresponding author Abstract This paper clarifies the confusion relating to the publication of Carlos de la Torre & Paul Bartsch’s taxonomic study of the Cuban Urocoptidae. This massive work, which described >500 new taxa, was completed in manuscript form in 1943, but was not published during the authors’ lifetime. In 1972 Miguel Jaume and Alfredo de la Torre (a nephew of C. de la Torre) published a slightly modified version of a large portion of this manuscript in the Circulares del Museo y Biblioteca de Zoología de la Habana, a mimeographed journal which is available for taxonomic purposes per ICZN Code Article 8. The 420 new taxa introduced in this paper were made available under the ICZN Code (even though many were differentiated only in identification keys) and should be attributed to C. de la Torre & Bartsch because the descriptions were copied from the 1943 manuscript and Jaume & A.
