Pasiphaciaprinceps Faxon, Mem. Mus. Comp. ZooL, xviii, 175, 1895. One large female, 167 mm. long, was dredged by the Albatross off Sea Lion Rock, Washington, in 859 fathoms, station 3075; and one small specimen about 47 mm. long, north of Unalaska, in 399 fathoms, station 3329- I have at hand only one specimen determined by Professor Smith. It was taken south of Marthas Vineyard in 538 fathoms, at station 2546. It measures 150 mm. long. It differs from the type in having the carina of the posterior two thirds of the carapace well marked though blunt, in the gastric tooth projecting well beyond the frontal margin, the anterior (or inferior) margin of this spine contiguous with the dorsal surface of the carapace in advance of the spine, and in having the merus of the first and second pairs of feet armed with numerous spines (instead of the first pair unarmed and the second pair few-spined). The antero-lateral sinus is rectangular, as in the figure of the type. In five smaller specimens from off Cape Romain, South Carolina, 353 fathoms, station 2626, and two from off Marthas Vineyard, 349 fathoms, station 1093, the gastric tooth projects only a little beyond the frontal marg
