REPORT ON THE AMPHIPODA. 435 



precedence. Figures and descriptions are given of both sexes of Sunamphithoii gam- 

 maroides. This I believe to be identical with the partially described Amphithoe 

 gammaroides of Spence Bate. Both sexes are described of Sunamphithoe conformata, 

 Sp. Bate, with the suggestion that Sunamphithoe liamulus, Sp. Bate, is in fact not a 

 separate species, but the female of Sunamphithoe conformata. The name of the species, 

 however, should be hamulus, although the synonjTuy, as given both in the Brit. Mus. 

 Catal. and in the Sessile-eyed Crustacea, leads to the (erroneous) inference that conformata 

 was the earlier established. As a matter of fact hamulus stands first at the original 

 contemporary institution of the two names.

No new species are described in this paper, which was intended as a supplement to Mr. Parfitt's 

 Catalogue, 1873. Cf-rayia imbricata, Sp. Bate, is figured, and notice taken that, contrary 

 to one of the characters assigned to the genus Gratjia, it has an accessory flagellum on 

 the upper antenns. This species has since been recognised as the young of Amathilla 

 sdbini (homari, Fabr.). The suggestion is made that Sulcator arenarius, Sp. Bate, is 

 probably the same as the Lepidacti/Us of Say. This surmise has since been confirmed by 

 S. I. Smith. Phxdra Icinahani, Spence Bate, was included in the list by mistake.

Report upon the invertebrate animals of Vineyard Sound and adjacent waters, 

 with an account of the physical features of the region. Extracted from the Report 

 of Professor S. F. Baird, Commissioner of Fish and Fisheries, on the condition of 

 the sea-fisheries of the South Coast of New England in 1871 and 1872. Washington, 

 1874. 



The Amphipoda in this report were identified by Mr. S. I. Smith. At page 19 (313) 

 Mr. Verrill says, " these small Crustacea .... together with the shrimps, constitute 

 a very large part of the food of most of our more mluable edible fishes, both of the fresh 

 and salt icaters." The Orchestia agilis of Smith, "occurs in countless numbers beneath 

 the masses of decaying sea-weeds." "A much larger species, and one of the largest of all 

 the amphipods, is the Gammarus ornatus." " The males are much larger than the 

 females, and sometimes become nearly an inch and a half long." " The only good 

 English name that I have ever heard for these creatures is that of ' scuds,' given by 

 a small boy, in reference to their rapid and peculiar motions." Other species are 

 mentioned, which will be noticed further on. In a " list of species inhabiting the rocky 

 shores of the sounds and bays," p. 37 (331) eleven Amphipods are named. 



Of Talorchestia longicornis and Talorrhestia megalophthahiia, of the sandy shores, he says, 

 " when driven from their burrows by unusually high tides or storms they are capable of 

 swimming actively in the water," p. 42 (336). Of the sandy shore species he mentions 

 also Orchestia agilis, Lepidaciglis dytiscus, Unciola iirorafa. To the muddy shores six 

 species of Amphipoda are assigned, p. 83 (377). Among the species commonly found on
