Podochela (Coryrhynchus) mexicana Rathbun, Proc. U. S. Nat. Mus., 

 vol. 16, 1893, p. 225 (type-locality, Gulf of California, 11 fathoms; holo- 

 type, Cat. No. 17330, U. S. N. M.). 



Diagnosis. — Rostrum short, rounded. Neck short. Margins of 

 basal antennal article thin, prominent. Legs filiform, propodites 

 without thumb-process, dactyli short. Sternum vermiculated. 



Description. — ^A species with short neck, very high gastric region, 

 two prominent gastric tubercles, cardiac tubercle uncommonly large, 

 laminate, the lamina continued forward in a blunt ridge; a large, 

 laminate, hepatic lobe, a thin pterygostomian ridge bearing a small 

 lobe. Rostrum short, arcuate, thin. Basal antennal article anteriorly 

 narrowed, margins thin, outer margin broadly bilobed. 



Chelipeds of a probably immature male feeble, palms slightly 

 swollen, fingers meeting. Legs slender; first one less than three 

 times as long as carapace, its propodus slender, about seven times 

 as long as dactylus, which is unarmed, slenderer, and less curved than 

 in the other legs; fourth leg about as long as carapace; second, third, 

 and fourth legs similar, diminishing successively, as do also their 

 propodal segments, which are a little thickened distally, that of the 

 second leg three times as long as dactylus, that of the fourth leg twice 

 as long as dactylus, that of the third leg intermediate; the three dac- 

 tyli are of the same size and form. 



Sternum and basal segments of legs vermiculated. Sternal seg- 

 ments in the form of raised plates with sharp edges and separated by 

 deep depressions. 



Said by Stimpson to be more hairy than riisei or lamelligera. 



Measurements. — Male (17330), length of carapace 10, width 8^ 

 length of cheliped about 12, of first leg about 27, second 21, fourth 

 11 mm. Female (Stimpson), length of carapace 0.52 inch (13.2 mm.), 

 width 0.42 inch (10.7 mm.).
