[358, Cast]. Pemphix Seurii, Meyer. This extinct Lobster has a carapace divided into three parts, of which the anterior corresponds to the abdom- inal region, the middle to the heart and genital regions, and the posterior to the branchial. It was by these long-bodied forms (Macrura) that the Decapod Crustaceans were at first represented in the Geological Series. The specimen is from the Muschelkalk (Middle Trias), Crailsheim, Wurtemberg. Original in the Ward Collection of the University of Roch- ester. Size, 6x3. No. 135. [1202, Cast]. Hoploparia (Astacus) longimana, Sow. This long-tailed Decapod resembles the Lobster. The cheeks are prolonged in the shape of semi-cylindrical horns; and the fore-arms are very long and unequal. From the Greensand, Lyme-Regis, England.
