Fig. 163. Ocypode gaudichaudii, X % (from Milne Edwards and Lueas, after 

 Bathbun). 



Characters. — Carapace squarish, broader than long, anterior corners flattened; 

 front between the eyes narrow, bent down. Eye-stalks large, elongated, prolonged 

 beyond the corneae in a slender style. Chelipeds stout, somewhat unequal, rough; 

 fingers with truncate ends. Ambulatory legs long, finely roughened. 



Dimensions. — Of specimens from Peru, examined by Miss Bathbun: width 

 about 40 mm. 



Type Locality. — Chile. 



Distribution. — Prom Lower California to Chile; Galapagos Islands; Honolulu. 

 Three young specimens from San Pablo, California, are in the Museum of Com- 

 parative Zoology; determined by Dr. Faxon (Bathbun). In view of the tropical 

 distribution of this species, it is very probable that the label on this lot is either 

 incorrect or the result of an exchange. 



Genus Uca Leach 



Carapace transverse-quadrate; antennules folded longitudinally. Eye-stalks 

 long and slender ; cornea short, terminal, confined to distal end of eye-stalk. 

 Exopodite of outer maxillipeds with flagellum. Chelipeds of male strikingly 

 unequal, hand of larger one very large, fingers longer than the palm, hand of 

 smaller feeble; both chelipeds in female feeble.
