 1858. 



Carapax anteriorly naked and glabrous, marked nearly as in P. 

 pimctulatus. The lateral triangular points of the front (those be- 

 tween the bases of the eyes and antennae) are rather strongly prom- 

 inent. Eye-peduncles equaling the anterior margin of the carapax 

 in length, but a Httle shorter than the third joint of the antennulse. 

 Ophthalmic scales large, with four minute equal spiniform teeth near 

 the apex. Peduncle of the antennae shorter than the eyes ; acicle 

 small and slender. Feet spinulose or granulose above, and mod- 

 erately invested with long hair. Left cheliped rather short, a little 

 overreaching the penult joint of the first ambulatory feet, its mar- 

 gins regularly crenulated ; lower surface smooth. In the left-hand 

 foot of the third pair the last two joints are broad and deeply ex- 

 cavated on the outer side, with crenulated and thickly ciliated mar- 

 gins, and a median longitudinal ridge, the surface near the superior 

 margin and between the median ridge and the lower margin being 

 elegantly sculptured with transverse striae or impressed lines corre- 

 sponding to the crenulations of the edges. General length in a male 

 specimen, 1.5; length of carapax, 0.34; breadth of front, 0.165 inch. 



It has the general appearance of P. punctuJatus and the concave 

 left foot of P. setifcr. The concavity of the foot, however, is in the 

 latter species smooth. 



It was found in Kagosinia luU', lapan.
