Fig. 163. Ocypode gaudichaudii, X 4 (from Milne Edwards and Lucas, after 
Rathbun). 
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 Rathbun: width 
about 40 mm. 
Type Locality.—Chile. 
Distribution—From 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 (Rathbun). 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. Hye-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.
