NO. 2135. NEW PHILIPPINE CRABS— RATH BUN. 557 



Second and third segments of antenna wide and thin, with lobed 

 margins. Merognath deeply grooved through the middle. Sternum 

 and abdomen (male) tuberculate; penultimate segment of abdomen 

 armed with a conical, sharp, slightly curved, downward-pointing 

 spine. 



Cheliped a little more than three times as long as carapace, rough 

 with rasp-like tubercles and large lobes and spines; the merus has 

 5 tubercles (3 large) on outer margin, about 10 (I large) on inner 

 margin, 7 low, smooth, and subequal on lower margin; of tubercles 

 on upper surface one is as large as any of the marginal ones. On 

 the carpus one tubercle, and that near the middle, is enlarged and 

 only to a moderate size. The manus has 5 tubercles on outer margin, 

 of which 3 are the largest on the crab and are flattened, 2 of them 

 subtruncate; about 10 tubercles on inner margin, somewhat saw- 

 toothed in shape, 2 near the distal end enlarged into conical spines; 

 on the lower margin about 11 smooth, low tubercles like those of 

 the merus; on the upper surface a much enlarged tubercle as on the 

 merus. Fingers elongate, basal half of a reddish color, distal half 

 white except for the tips, which are brown; surface rough with 

 granules, a large tubercle or lobe on top of dactylus toward its base. 



Legs c^dindrical, merus crossed w^ith two (in the last pair one) 

 bands of brownish-red (in alcohol) ; dactyli with a short velvety 

 coat, the last one the longest ; last pair of legs roughened with small 

 tubercles on the merus and propodus and 2 lobes on upper margin of 

 carpus. 



Of described species, this comes nearest to P. (/?.) cyhelis Alcock.^ 

 It has a similar form, except as to the rostrum, the carapace is pitted 

 and the cheliped has about the same amount of armature; but all 

 the spines of cyhelis are acute, the cardiac region has 2 strong 

 spines, and the rostrum has a narrow^ terminal lobe. 



PARTHENOPE (PSEUDOLAMBRUS) FARVA, new species.

Carapace high, the branchial regions deeply separated from the 

 gastro-cardiac; a large rounded tubercle on the gastric and on the 

 cardiac region ; 2 lines of granules diverge anteriorly from the gastric 

 tubercle ; cardiac region sparingly furnished with granules ; branch- 

 ial ridge curved (concave outward), marked by 4 tubercles and a few
