NOTICC OF A IV£1V^ SPECIES OF THE ' WILLEMOESIA aROlTP OF 

 CRUSTACEA' (BECENT ERVOiVTID^). 



By SII>i\EV i. SMITH. 



Among the very interesting collections of marine invertebrate ani- 

 mals made during the past two years by the fishermen of Gloucester, 

 Mass., and presented to the United States Fish Commission, for the 

 National Museum, there are two species of podophthalinous Crustacea 

 of peculiar interest. One of these is a remarkable Paguroid which I 

 have already described (Trans. Connecticut Acad., v, p. 50, 1879), but 

 of which several additional specimens have been received since the de- 

 scription was published ; the other, which is the subject of this notice, 

 belongs to the "Willemoesia group of Crustacea," first brought into 

 ]>rominent notice by the researches in connection with the Challenger 

 Expedition. Of the latter species I have seen only a single specimen, 

 which was taken at a depth of 250 fathoms, oflf the coast of Nova Scotia, 

 southeast of Sable Island, latitude 43° 10' north, longitude 61° 20' west, 

 by Captain Thomas Olsen, of the schooner Epes Tarr. This specimen 

 is not in very good condition, having been dried (probably after being 

 taken from the stomach of some fish, though there is very little evidence 

 of digestion having begun), and the internal organs consequently de- 

 stroyed, but it is still sufficient to throw considerable light upon the 

 structural peculiarities of the group to which it belongs, and on this ac- 

 count particularly T am induced to publish a special notice of it. 



Of the three genera into which Bate* has recently separated the 

 forms of the " Willemoesia group," our species should unquestionably 

 be referred to Pentacheles, but, on account of the at present uncertain
