calcareous molar-like teeth. In the smaller hand the palm is not so strongly 

 inflated;, the fingers are longer and straighter and more deeply excavated 

 within; the corneous tips are more extensive and the calcareous teeth are 

 smaller and more numerous. Ambulatory legs spiny, somewhat com- 

 pressed; dactyls about two-thirds the length of the propodi. Abdomen 

 short, broad, and soft, spines not so large as on the carapace ; on the 

 basal segment there is a median plate and two wide lateral ones ; the 

 plate on the j^enultimate segment is oblong; the last one is small, rounded, 

 and about as long as wide. Length of carapace from tip of rostrum, 58 

 mm.; width of carapace, 58 mm." (Holmes, Occas. Papers of Calif. Acad.

According to Arnold (Sea Beach at Ebb Tide), this form is a deep 

 water species and has been brought ashore at Monterey, California, by 

 fishermen who have found it in the stomachs of fishes. Miss Rathbun re- 

 ports it for Puget Sound. It ranges in depths, up to 16 fathoms. 



Prof. O. B. Johnson of the University of Washington has left a 

 mounted specimen labeled "Friday Harbor" in the University Museum.
