Crustacea on the coast of New England. 263 



NautilograpSUS minutUS Milue-Edwards. 



A large male of this common pelagic species of the Gulf Stream 

 was taken at Woods' Holl, Vineyard Sound, September 11, 18Y7, by 

 V. N. Edwards, Length of carapax, 15-1'"'"; greatest breadth, 14-8; 

 breadth of front between bases of eyes, 9'7 ; breadth between ante- 

 rior angles, 13*0. 



It has been recorded from the English coast by White, Bell, and 

 others ; the Medeterranean, Heller ; Cape St. Lucas, Stimpson ; 

 Indian Ocean, Milne-Edwards. 



Pinnotheres ostreurn Say is brought north in considerable numbers 

 in oysters from the Chesapeake and, very likely, occasionally survives 

 for a considerable time in oysters planted on the New England coast, 

 but, as far as I can learn, it is never found in native New England 

 oysters or in those which have been planted here for any considerable 

 time. It may, therefore, properly have claim to a place in the list. 

 I have never seen the male on the New England coast. The figure, 

 purporting to represent the male of this species, which I have given 

 in the Report on the Invertebrate Animals of Vineyard Sound, is in 

 reality the figure of the male of Pinnotheres maculatus. 



NeptunuS Sayi stimpson (ex Gibbes). 



Young specimens of this common pelagic species of the Gulf Stream 

 were several times taken in Vineyard Sound during August and 

 September, 1875. None of the specimens observed were more than 

 12 to 15""" across the carapax. The megalops of this, or of some 

 closely allied species was taken at the same time. 



Calappa marmorata Fabricius. 



While at Woods' Holl, with the party of the U. S. Fish Commis- 

 sion, in the summer of 1875, I was surprised at the occurrence of a 

 very remarkable megalops evidently an early stage of some species 

 of Calappa^ though the genus was at the time not known to me to 

 occur, on our coast, north of the Carolinas. Before leaving Woods' 

 Holl, however, Mr. V. N. Edwards informed me that a small crab, 

 unlike any before known to him, had been found the previous season, 

 under stones at low" w^ater, on Ram Island near Woods' Holl, by Mr. 

 Benja. Smith. The specimen was brought to me by Mr. Edwards 

 and proved to be a young Calapjxi mannorata, with the carapax 

 22"'™ long. The shores of the same island and other similar localities 

 were carefully senrched, during September, 1875, without finding- 

 additional specimens. In 1878, however, Mr. Edwards forwarded
