300 A. E. Verrill Decapod Crustacea of Bermuda. 



of the chelipeds has five sharp teeth on the front margin : the lateral 

 spines are long and sharp, curved for\\ard a little ; there are usually 

 one or two round silvery spots near the liases of the anterior mar- 

 ginal teeth, on each. side. It is a rather small species. A female 

 with the adult form of the abdomen, from Egmont Key, Fla., has 

 the carapace only -'<>'"'" long, 40""" wide, including spines. 



A female from Ft. Macon. N. C. (coll. Dr. V:irr..\v. L871, N". 

 MIST), has the adult form of the abdomen, Imt no eggs. Its carapace 

 is 25"' m long; 51"' m broad with spines: without spines, 4n-'" \\ide: 

 length of cliche, :!1""": height, 7..V 11 "'. 



The four inner frontal teeth are about e.|iial in length, but the 

 two inner are narrower. The merus of the -\\ imming le-'s has a 

 ro\v of 5 or G small acute spinules on it- po-ierior distal edge, the 

 outer ones longer. The anterior two pairs of le^-- are llattened, with 

 the merus as well as the distal segments fringed. The disial end of 

 the dorsal carina of the- chela- is sub piniform, 90 that in profile it 

 looks a little like a second spine, in front of the principal one. which 

 i- sharp and divergent. The maims ha-* five Strong granulated rihs 

 on the superior and outer surface*-, with deep hairy grooves lietween 

 them. The dactylus has four rihs. lie-ides an inner one. The sur- 

 face of the rihs, when the hairs are removed, is -hininu or -ilverv. 







The carapace is strongly granulated and hairy ; the small silvery 

 spots* are very distinct. The meru- of the right cheliped has six 

 inner marginal spines, that of the left chelipe<l only live. They are 

 sharp and directed forward, hut not so near together a- in the ti-ui-e; 

 usually there are hut five. 



The chelipeds are very long, being longer than in the figure. The 

 length of the merus exceeds half the total breadth of the carapace. 

 The chela- and carpi are also elongated. When extended, the 

 expanse of the chelipeds is seven times the length of the carapace. 

 In a male (981a) the carapace is -_'4 n "" long; expanse of chelipeds, 

 168 mm ; when folded the end of the merus projects 15 mra beyond tip 

 of the lateral spine. The ambulatory legs are -also long and much 

 flattened. 



Off C. Hatteras, Str. "Albatross," Nov. 9, 1883, sta. 2107, in 10 

 fathoms, three, one with eggs (Smith) ; off C. Hatteras, .1 .-t at ions, 

 13-48 fath., 1884, 16 specimens, 1886 (Smith). 



* These spots are variable in form and number and are often lacking on one 

 side. They look as if they might have been made by the tips of the claws of 

 the opposite sex during the mating season. The surface of the carapace becomes 

 silvery whenever the hairs are rubbed off by friction.
