A specimen undoubtedly belonging to this species is in the possession 

 of the Johns HoT)kins University, having been sent by F. W. Simonds. 

 It was caught by a fisherman in a gill net oft' Dead Man's Island, San 

 Pedro, Cal. Tliis specimen corresponds exactly to Miers's description, 

 except that the telson can hardly be said to have ''8 large nuir- 

 ginalteeth." It has the usual six marginal spines, the submedian pair 

 having small movable tips, and a broad rounded denticle between the 

 submedian and intermediate spine on each side. (See fig. 3, p, 505.) 

 An additional minute movable spine should appear on the raptorial 

 manus of this figure, and also a minute denticle on the outer edge of 

 the basal prolongation of the uropod. 



The color of the living animal, according to Mr. Simonds's memoran- 

 dum, was violet. 



The length of the body is 14.5 cm.
