Dimensions. — Type, ovigerous female: approximate length, 28 mm.; length of 

 carapace and rostrum 9.4 mm., of rostrum 4.4 mm. 



Type Locality. — Monterey Bay, California. 



Distribution. — Puget Sound to Lower California, 44 to 77 fathoms (Eathbun).

 terms it is a bispinosa with the slender spine' of the rostrum broken off; but a 

 closer examination shows other and more radical differences (Eathbun).

Cliaracters. — Near S. bispinosa. Posterior median tooth of carapace consider- 

 ably in front of middle. Eostrum shorter than in S. bispinosa; upper and lower 

 laminae narrower and extending nearer the tip ; armed with nine to fourteen teeth
