This species resembles most S. paludicola 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.— Yxom 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. N.) ; Ref- 

 uge Cove, Port Chatham, i $ (W. H. Dall) ; Puget Sound (Caiman).

 Sitka, 10 fathoms (Harriman Expedition); Puget Sound (Walker, also 



collected by T. Kincaid). 

 San Pablo Bay, taken in Chinese shrimp-nets {Albatross).

 San Diego, 10 fathoms (H. Hemphill); south of San Diego Bay, 22 



fathoms {Albatross ^izSAon 3679). 

 Southern CaHfornia (W. H. Dall). 



I have a little doubt about the single speci- 

 men from Sitka, as it is much mutilated ; it is 

 not, however, referable to any other species. 



The male differs peculiarly from the female. 

 It has the customary points of difference : It is

1 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.
