facial region occupies nearly the width of carapace. The sutures of 

 the sternal plastron of the female are lightly marked and do not 

 overreach the line of the third pair of feet. Ambulatories slender, 

 shorter than in Homolodromia; last two pairs with subcheliform 

 extremity, the propodite not forming a distinct digit. Epimera of 

 segments of female abdomen in contact ; terminal segment of enormous 

 size.

which are clothed in long fine hairs. Carapace more convex trans- 

 versely than from front to rear; side margins nearly parallel; they 

 diverge slightly behind, the carapace being wider in its posterior than 

 anterior part. Front formed of two large triangular teeth between 

 which there is a small median point, a vertical prolongation from the 

 epistome. Upper orbital border interrupted toward the outside by a 

 narrow fissure; a wide V-sinus outside the orbit and below the antero- 

 lateral angle; suborbital border lobiform; some very small spines on 

 the orbital lobes and the anterior part of the lateral borders of the 

 carapace. The ocular peduncles turn laterally in orbital cavity; they
