No. 10 GARTH : BRACHYURAN FAUNA OF THE GALAPAGOS 345 



Chelipeds and ambulatory legs lightly touched with red, appearing much 

 lighter in color than the carapace. Eyes dark brown. Ventral side white. 

 (Petersen) (Notes made from a Gulf of California specimen.) 



Habitat. — Sand. 



Depth. — 35-55 fms. 



Remarks. — Since this species was not taken by the earlier Allan Han- 

 cock Expeditions in the Galapagos Islands, it is not recorded in Rathbun 

 (1937) as a member of the Galapagos fauna. The single female from 

 Sulivan Bay, James Island, has been compared with the type series from 

 La Plata Island, Ecuador, also dredged by Velero HI collectors, and 

 agrees in every particular. 



R. ecuadorensis is now recorded from the Galapagos Islands. The 

 specimen illustrated is, however, a paratype from La Plata Island, Ecua- 

 dor.
