62 S. I. /Smith — Crustaceans of the Atlantic Coast. 



Ledge, in 52 to 90 fathoms, rocky, 18*73, — common. Near St. 

 George's Banks!, 110 fathoms, "sand and mud with a few stones," 

 1872, — one young specimen. Bay of Fundy !, 40 to 50 fathoms, 

 rocky, Aug. 14, 1868, — a female carrying eggs; and off White Head, 

 Grand Menan, 40 to 50 fathoms, 1872. On the European coast it has 

 been recorded from Scotland ! (Norman), the North Sea (Metzger), and 

 the west coast of Norway !, 150 to 200 fathoms (G. O. Sars). 



As the above record of stations shows, this species is an inhabitant 

 of hard, and usually rocky, bottoms in deep water. This is probably 

 the reason of its apparent rarity, since such localities are not com- 

 mon and are difficult of exploration with the dredge. 



European specimens, received from the coast of Norway through 

 Prof. G. O. Sars, agree with all the American specimens examined in 

 having well developed epipodi at the bases of the second, third and 

 fourth cephalothoi^acic legs, as well as in all other respects. The 

 dentition of the rostrum is subject to considerable variation. In 

 twenty-two specimens examined, varying from 17 to 27'""^ in length, 

 four had the formula, f ; seven, ^ ; nine, ^ ; one, f ; and one, -| ; — 

 each of the last two cases being adult specimens from Cashe's Ledge. 



Hippolyte Leach. 



In accordance with the rules for zoological nomenclature as at 

 present generally accepted, the name Hippolyte should not be 

 applied to the species now usually included under it and ought to be 

 restored to the species without mandibular palpi, and for which 

 Stimpson has proposed the new generic name Virbius. 



The genus Jlippolyte, as first proposed by Leach in 1813 or '14 

 (Edinburgh Encyclopaedia, American edition, vol. vii, p. 271),* con- 

 tains but one species, H. varians Leach, and in 1815 in the Transac- 

 tions of the Linnean Society, vol. xi, p. 347, varians is still retained 

 as the first species and a new species, inermis, added. In the first of 

 these publications there is, under Hippolyte^ the observation that " to 

 this genus the Cancer Astacus gibbosus of Montagu belongs," and in 

 both of them the " Cancer spinus of Sowerby" is referred to Alpheus. 

 In 1817, in the Malacostraca Podophthalmata Britannia^, however. 

 Leach says, " Montagu sent to me Hippolyte varians, the type of this 

 genus, as his Cancer astacus gibbosus, but he afterwards informed 



*I have not been able to examine the original edition. The American edition 

 seems, however, at least as far as the article under consideration is concerned, to be 

 an exact reprint of the original, with changes only in paging and division into 

 volumes.
