and close to the anterior margin on either side some of these 

 are arranged in a short keel-like series. Median keels com- 

 paratively well developed, especially the posterior median 

 pair, which 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 

 re])resented by one or two enlarged granules only. 



Anterior s^er«ites smooth and shining, and 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. Intercarinal 

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

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

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

 appear a little smoother than the preceding ones, but not 

 nearly so smooth as tlie fifth ; the granules between the 

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

 extent as those of the other intercarinal spaces of this 

 segment. Caudal segments 1-3 each with 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 superior all the keels of the fourth 

 .«egment 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. Fifth caudal segment smooth, 

 shining, and without any trace of keels, but iurnished 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 })resent on the dorsal surface of the hand, but it 

 does not reach the apical end. Movable finger more than 

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

 granules.
