NO. 2135. NEW PHILIPPINE CRABS— RAT II BUN. 559 



CRYPTOPODIA ANGUSTA, new species. 



Type-locality. — China Sea, near Hongkong: lat. 21° 42' N. ; long. 

 114° 50' E.; 38 fathoms; sft. gy. M. ; temp. 72.1° F.; Aug. 9, 1908; 

 station 5302, Albatross. 



Holotype.— Female. Cat. No. 48249, U.S.N.M. 



Measurerrhents. — Length of carapace, 11.4; width of carapace at 

 lateral angles, 15 ; width at postero-lateral angles, 12.8. 



Carapace narrow for a Cryptopodia^ the several slopes from the 

 central triangular depression being of nearly equal depth; the de- 

 pression has 3 spines on its posterior border, one of which is slender 

 and surmounts the cardiac region, the others short, each on the 

 highest point of the more elevated branchial region ; 2 sharp tuber- 

 cles or spines side by, side at the anterior end of the depression; the 

 ridges and 3 elevations marked with rasp-like granules. Antero- 

 lateral margins nearly straight and in line with sides of rostrum, 

 inner margins of orbits parallel, postero-lateral margins sloping 

 backward and inward, posterior margin transverse ; margins dentate, 

 teeth denticulated and separated mostly by closed fissures; 3 teeth 

 in front of lateral angle more pronounced, also the tooth at the 

 postero-lateral angle and 4 others on the posterior margin which 

 divide that margin into 5 sinuses, whose relative width is expressed 

 by 1.5 : 3.5 : 3 : 3.5 : 1.5. 



Chelipeds very unequal, perhaps accidentally so; upper margins 

 of merus and manus dentate, lower margin and lower surface tuber- 

 culate; 3 enlarged teeth on inner and outer margins of merus and 

 outer margin of manus, 4 enlarged teeth on inner margin of manus; 

 base of dactylus with 2 or 3 strong teeth. xVmbulatory legs cristate ; 

 lower margins of last pair dentate save on the dactylus, lower mar- 

 gins of ischium and merus of first three pairs sparingly dentate. 



In the 5 spines on the dorsal surface this species resembles C. 

 angulata cippifer Alcock,^ but that species or subspecies is much 

 wider, its lateral angles further forward and more produced, its 

 front between the eyes not having parallel sides.
