It differs, however, in its shorter rostrum, which is two thirds or four fifths the length of the carapace; in the shorter antennular scale, only slightly exceeding the first segment of the peduncle; in the shape of the antennal scale, which is broadly arcuate at the end, the blade exceeding the spine; in lacking an epipod on the second pereiopod. Distribution. — From Sitka, Alaska, southward to Puget Sound: Sitka (Brandt); Cape Fox, 3 $ (W. R. Coe, Harriman Expedition); Tongass, July 16, 1885, 3 ? (Lieutenant H. E. Nichols, U. S.
