This species resembles most .S. pa/udicola of California. 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.—¥rom Sitka, Alaska, southward to Puget Sound: 
Sitka (Brandt); Cape Fox, 39 (W. R. Coe, Harriman Expedition) ; 
Tongass, July 16, 1885, 3 9 (Lieutenant H. E. Nichols, U.S. N.); Ref-

1] have considered that De Haan’s use of this name on plate xLv did not invalidate 
it for Stimpson’s species, because De Haan in his Errata (p. 244), as well as in the 
explanatory text (p. 194), corrected the name of his species to Sicyonia cristata, the 
correction appearing, so far as I am able to ascertain, simultaneously with the plate.
