tooth on the middle of the movable finger is wanting, both of which 

 points are very characteristic of tumida. 



The other species of Crustacea which are common to both the Asiatic 

 and American shores of the Pacific are Trapezia maculata, Liomera lata, 

 Liomera cinctimana and Pachygrapsiis crassipes. The latter, a subterres- 

 trial crab, was obtained by Stimpson from the port of Simoda, Japan. 

 The first three are littoral in their habits, and are Indo-Pacific species. 

 On the American side all of these species have come, so far, from the 

 Lower Californian coast only.
