Figure 218. — Podochela riisei Stimpson. Animal in dorsal 

 view, legs of left side not shown, 5 mm. indicated. 



rounded in front, deeply excavated below for 

 antennules, carinate above and with a tuft of 

 curled hairs. Orbits rounded, margins thickened 

 and with a row of hairs. Eyestalks short and 

 stout, cornea oblique, dorsal emargination with 

 distal tubercle tufted. Basal article of antenna 

 with a high crest on each margin. Sternum of 

 male thrown into ridges radiating to bases of legs. 



Chelipeds slender in both sexes, fingers in con- 

 tact throughout their length (stouter and slightly 

 agape proximally in adult males). First pair of 

 walking legs stouter than others, about three times 

 as long as carapace; upper surface of all legs with 

 regularly spaced tufts of stiff curled hairs. 



Abdomen of male with six, female with five, 

 free segments. 



Measurements. — Carapace : male, length, 21 

 mm., width, 16 mm.; female, length, 23 mm., 

 width, 20 mm. 



Variations. — The rostrum is variable in shape 

 and length. Margins of the basal antennal articles 

 are thick in old individuals but may be thin in 

 younger ones. Sternal segments of males usually 

 have rounded surfaces but are sometimes flattened. 



Color. — Overall color light brown ; legs lighter, 

 grading to almost off white or pale yellow; chelae 

 and chelipeds nearly white to almost transparent; 

 carapace darker on lateral aspects of urogastric 

 and cardiac regions, as well as at posterolateral 

 portions of metabranchial regions. AYass (1955) 

 reported brick red specimens. 



Habitat. — Has been taken from among hydroids 

 on pilings at Beaufort, NO, and in rocky areas 

 in northwestern Florida (Wass, 1955) ; shallow 

 water to 30 fathoms. 



Type locality. — Island of St. Thomas, [West 

 Indies]. 



Known range. — North Carolina to Campeche, 

 Mexico; through West Indies to St. Thomas; Rio 

 de Janeiro and south of Pernambuco, Brazil; 

 Bermuda. 



Remarks. — Ovigerous females have been taken 

 in North Carolina in September. They have been 

 taken in Florida from June to August and from 

 November to February (U.S. National Museum 

 records).

 text-fig. 9c, pis. 12-13 (rev.). 



Recognition characters. — Closely resembling 

 Podochela riisei. Rostrum narrower at base. 

 Pterygostomian region bearing a long thin lamina 

 either subtriangular or produced downward in a 

 lobe. Sternal segments flat with sharp cristate 

 margins. 



Chelipeds of adult male less inflated than in 

 P. riisei, proximal gape narrower, teeth on cutting 

 edsres more numerous and uniform in size. Walk-
