the posterior border of the hand the external and internal are of 

 about equal strenght, while the median one is almost obsolete; digiti 

 short and in contact throughout, the movable about equal in lenght 

 to or perhaps a little longer than the hand-back. 



Legs almost smooth, the posterior two more granular than the 

 anterior two ; the distal tibial segment much longer than the proximal. 



Pectines with three teeth. 



Measurements in millimeters. Total length 19, céphalothorax, length 

 2.8, width 2.5; tail; length 10, length of first three segments 3.5, 

 of the 5 th 2.5, of vesicle and aculeus 3; manus width 2.2, length 

 of hand-back 2.5, of movable digit 2.6. 



This species differs from variegatus and borneensis in its much 

 narrower hand , from truncatus in at least the absence of keels on the 

 upper surface of the fifth caudal segment, from cavernicola in having 

 a wider hand and the median keel on its upper surface obsolete — 

 a character in which as well as in its smooth hands, it further differs 

 from variegatus.

Many adult and immature specimens of both sexes from Buitenzorg 

 in Java. 



The colour of this species is green or nearly black, being generally 

 more as less tinted with ferruginous. The vesicle is either piceous or 

 ferruginous in the adult, but in the young it is entirely flavous. 



Apart from its larger pectines and divided genital operculum, the 

 male is not furnished with striking sexual characters. The tail, ho- 

 wever, is a little longer than in the female. 



This species is evidently very common in Java and I am not ac- 

 quainted with any reliable evidence of its occurence elsewhere. In 

 Keyserling's collection, however, there is a single specimen of it tic-
