United States National Museum, Washington, December 31, 1879. notice: of a new species of the 'wiei^emoesia croup of crustacea' (recent eryontid.e). By SIOI^EY I. SrrilTH. Among the very interesting collections of marine invertebrate ani-mals made during tlie 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 podophthalmous Crustacea of peculiar interest. One of these is a remarkable Paguroid which I have already described (Trans. Connecticut Acad., v, p. 50, 1S79), but of which several additional specnnens 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 prominent notice by the researches in connection with the Challenger Expedition. Of the latter species 1 have seen only a single specimen, which was taken at a depth of 250 fathoms, oft" 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, tliough there is very little evidence of digestion having begun), and the internal organs consequently de-stroyed, but it is still suflflcient to throw considerable light upon the structural peculiarities of the group to which it belongs, and on this ac-count particularly I 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 uucertain »0n the Willemoesia Group of Crustacea. < Annals and Magazine Nat.
