Female.—The nearest approach in the Pacific to the S. gaimardi of 
the Atlantic. Associated with S. zownsendi, with which it may easily be 
confounded; distinguished from it as follows: 
The rostrum is rather more concave above instead of nearly straight ; 
it reaches end of, or may exceed, antennal scale. 
The antennular scale does not reach the end of the second segment of 
the peduncle. 
The antennular peduncle reaches middle of antennal scale (length 
measured along outer margin). The second segment is appreciably 
longer than the third. 
The antennal scale, measured on its outer margin, is much shorter than 
the carapace. 
The outer maxillipeds overlap the distal fourth of the antennal scale, 
and may reach the end of the scale. 
The second pereiopod is commonly destitute of an epipod; sometimes
