122 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL.21 



Localities subsequently reported, with collectors: Mexico: Gulf of 

 California: off Adair Bay, 11 fathoms, Albatross (Rathbun, 1893b; 

 type of Podochela (C.) mexicana) ; Arena Bank and Santa Inez Bay, 

 11-35 fathoms, Zaca (Crane) ; Ecuador: 01° 07' N, 79° 53' W, 9-27 m, 

 Askoy (Garth). 



Atlantic analogue: Podochela riisei Stimpson. 



Diagnosis: Rostrum thin, hood-shaped, without median carina. A 

 postorbital granule. Basal antennal article concave ventrally, outer 

 edge bilobed. First ambulatory leg two and two-thirds to two and 

 three-fourths times carapace length, dactyl between one-fifth and one- 

 sixth the propodal length. Last pair of legs unusually long, dactyl one- 

 half propodal length. Manus of adult male swollen, fingers gaping. 

 Sternal plates deeply separated, bases of legs vermiculate. Curved hair 

 count 6-8. 



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 nar- 

 rowed, margins thin, outer margin broadly bilobed. 



Chelipeds of a probably immature male [holotype of Podochela 

 (C.) mexicana] 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; dactylus 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; propodal segments 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 dactyli of the same size and form. 



Sternum and basal segments of legs vermiculated. Sternal segments 

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

 depressions. (Rathbun, 1925, modified) 



Merus of the third maxilliped noticeably longer than broad, its 

 antcrointemal angle distinctly produced and sharpened. Dactyli of all 

 the walking legs falcate, those of the second to fourth pairs denticulate 

 as well. A single tubercle on the first abdominal segment. Paired 

 tubercles in advance of the abdomen and at the base of the chelipeds 

 wanting, but their place taken by an obtusely angled, spinulous ridge. 

 Orbital margins hairy and finely denticulate.
