Material. Six well-preserved specimens, five of which were 

 adult females and one an adult male, have been examined. 



Head. The frontal sense-organ is scarcely more than twice 

 as long as broad; the branches with acute apex. Four sense- 

 organs in each lateral groups (fig. 2 b); each organ on an ave- 

 rage three times longer than broad, with acute apex. — The 

 large sternum (fig. 2 a) has posteriorly a straight transverse row 

 of eight hairs, close in advance thereof a hair in tlie median 

 line, and from this hair proceed a pair of oblique irregular rows 

 of three hairs outward and much forward. (One may also say 

 that these seven hairs in advance of the posterior row are arran- 

 ged in four transverse lines, the posterior of them with one 

 hair, each of the thi-ee others with two hairs). 



Chela (fig. 2 c). Each finger has eight robust, acute spines, 

 the distal one conspicuously larger than the following ones; the 

 more proximal spines have a small cleft on the proximal margin.
