 surface of carapace dull yellow orange with numerous indistinct darker 

 small spots. Chelipeds as carapace, finger tips white. Ambulatory legs 

 white with but little color. Ventral side pale gray with light touches of 

 dull orange. (Petersen) 



Habitat. — Rock, frequently covered with red algae ; rock and sand ; 

 rock and shell ; sand. 

 Depth. — 3-70 fms. 



Remarks. — A single specimen taken on a reef north of Tagus Hill by 

 the Hopkins-Stanford Expedition appears to be the only previous Galapa- 

 gos record for the species. It is now known to occur throughout the archi- 

 pelago to a depth of 70 fms. 



All Galapagos Lissas were subjected to careful scrutiny in the hope 

 that some of them might prove to be L. tuberosa, encountered by Hancock 

 Expeditions from the Gulf of California to Colombia along the mainland. 

 However, none had the cristate legs and double crests on the carpus 

 characteristic of this species. 



Both sponge and bryozoan encrustations were observed on Galapagos 

 specimens.
