brevior, setd nudd. Abdomen uni-articulatum, apice subcylindrico

Sooloo Sea, west of the Island of Panay, January 27, 1842. 



Length, one-twentieth of an inch. Nearly colourless, with deep 

 red about the mouth and along the venter. Pigment of eyes red. 



The cephalothorax in a dorsal view is about as broad behind as in 

 front. The posterior angles are prolonged acute ; and those of the 

 small terminal segment lying between are acute and a little prolonged. 

 This last character, the conspicilla in contact, and the characters of 

 the abdomen, distinguish this species from the following. 



In a lateral view the abdomen is gradually tapering, and the upper 

 and under sides are nearly straight.
