and close to the anterior niarj^in on eltiier side some of these 

 are arran<red in a short ked-like series. Median keels com- 

 paratively well develo[)eil, especially the posterior median 

 pair, wliich are quite well marked and strong. 



Tergites granular; their lateral keels very short, even in 

 the hinder segments, and in most of the segments they are 

 represented by one or two enlarged granules only. 



Anterior s<tr/jj<«« smooth and shining, ajid at most with fine 

 granulation at the extreme margin only. Penultimate sternite 

 granular at the sides, but the granulation is very fine except 

 at the maigin. Last sternite granular throughout and with 

 tour granular keels. 



Tail increasing in size posteriorly; last segment slightly 

 swollen. Upper surface of segments 1-4 granular ; fifth seg- 

 ment with the upper surface almost smooth anteriorly, but the 

 shallow excavated area in which the median groove of this seg- 

 ment loses itself posteriorly is finely granular. lutcrcarinal 

 spaces of segments 1-3 distinctly granular; the granules of 

 those of the fourtli have run together so as to form a confused 

 network of low smooth ridges, and this causes tiie segment to 

 appear a little smoother than the preceding ones, but not 

 nearly so smooth as the fifth ; tiie granules between the 

 inferior median keels of the fourth are not fused to the same 

 extent as those of the other intercariual spaces of this 

 segment. Caudal segments 1-3 each wath ten distinct 

 keels, those of the first and second and the upper ones of 

 the third being distinctly granular. Terminal granule of the 

 two upper keels of the first two segments slightly enlarged. 

 Inferior lateral and ventral keels of the third segment smooth. 

 With the exception of the su[)erior all the keels of the fourth 

 .segment are smooth, and they are weaker than those of the 

 preceding segments ; the keels of the two upper pairs are 

 especially weak and have almost disappeared ; the medial 

 lateral is still visible in the anterior two-thirds of the segment, 

 but is exceedingly weak. Filth caudal segment smooth, 

 shining, and without any trace of keels, but lurnished with 

 large punctures. Vesicle smooth, shining, and with scattered 

 punctures ; the tooth under the aculeus large and blunt. 



Chela. — Hand furnished with granules, which are distri- 

 buted in an irregular manner; it has two well marked finger- 

 keels, the part of them which is situated on the hand itself 

 being granular, but the part on the finger smooth ; an outer 

 keel is also present on the dorsal surface of the hand, but it 

 does not reach the apical end. ]\Iovable finger more than 

 twice as long as the hand-back and with six median series of 

 granules.
