Abstract

Examination of all known specimens of decapod crustaceans from the Fox Hills Formation has resulted in recognition of five species and three distinctly different forms of pereiopods that cannot be assigned to a recognized taxon with certainty. Callichirus waagei n. sp. is proposed for a callianassid claw preserved within an Ophiomorpha burrow. Hoploparia sp. and Raninella oaheensis Bishop, 1978, are reported from the formation for the first time, and the cheliped of the latter species is noted, also for the first time. Latheticocarcinus shapiroi Bishop, 1988, the most common species of decapod in the formation, is re-described; the lateral flanks of this homolid crab are recognized for the first time, and the carapace is reconstructed. Necrocarcinus siouxensis Feldmann, Awotua and Welshenbaugh, 1976, is noted, but no new specimens were studied. All the decapods were preserved within concretions and all but one specimen of Hoploparia were disarticulated elements, suggesting that they may have been molted remains. Cuticle was well preserved and thin section examination of the lamellar structure of Hoploparia cuticle confirmed that, although thoroughly altered chemically, details of lamellar structure are retained.

Abstract

The taxon Cacurgus spilopterus Handlirsch, 1911, is revised, based on characters of the forewing venation, and is assigned to the Archaeorthoptera Béthoux and Nel, 2002, in which it occupies a basal position.

New and Historical Records of Polychelid Lobsters (Crustacea: Decapoda: Polychelidae) from the Yale Peabody Museum Collections

3 figs. (color)

Abstract

Examination of the polychelid collections in the Division of Invertebrate Zoology of the Yale Peabody Museum yielded eight species of these deep-sea lobsters, including syntypes of Polycheles nanus (Smith, 1884). Three species are reported for the first time from the New England Seamounts: Pentacheles laevis Bate, 1878, P. validus A. Milne Edwards, 1880, and Polycheles talismani (Bouvier, 1917), with all but P. validus being represented in the collections by eryoneicus larvae as well as adults. Polycheles amemiyai Yokoya, 1933, is recorded for the first time from the Philippines and a misidentification of a Belize Polycheles typhlops Heller, 1862, by Boone (1927) is corrected. Additional specimens of Polycheles perarmatus Holthuis, 1952, and P. sculptus Smith, 1880, are reported from the Gulf of Mexico and the western Atlantic. All eryoneicus larvae are identified to species and a discussion of the problems associated with historical records of eryoneicus larvae is provided.

Abstract

Recent field work and a review of catalogued specimens in the herpetology collections at the Yale Peabody has yielded 170 new town records for amphibians and reptiles in Connecticut. These are reported here, along with observations on the status of the red-ear slider (Trachemys scripta) in Connecticut.
