252 Mr. E. T. Pocock on 



in front and with an obsolete crest behind ; the last bearing 

 in its posterior half a sparsely granular prominence, behind 

 which is a smooth depression ; the lateral portion furnished 

 behind with two indistinct series of granules above, smooth 

 below, granular in front ; the lateral portion separated from 

 the superior portion by a distinct row of fine denticles. 



Sternites perfectly smooth ; all, except the last, marked 

 with an abbreviated sulcus on each side in front. 



Tail. — Inferior surface of the three proximal segments 

 smooth beneath, with very feebly developed keels ; the infero- 

 lateral keels of the third segment posteriorly showing faint 

 indications of denticulations ; inferior keels of the fourth 

 distinctly denticulated, those of the fifth strongly denticulated ; 

 superior keels of all the segments denticulated, the denticles 

 being stronger upon the posterior than upon the anterior 

 segments ; all the intercarinal spaces almost entirely smooth ; 

 vesicle smooth above, furnished below and at the sides with 

 finer and coarser denticulations ; aculeus gently curved. 



Chela. — Upper surface of humerus bounded behind and in 

 front with a row of strong denticles, and bearing others 

 scattered, larger and smaller, for the most part on its proxi- 

 mal two thirds ; anterior surface bounded below by a straight 

 row of denticles and above by an oblique series ; inferior 

 surface sniootli, bounded behind for a third of its length by 

 a row of small bluiit denticles ; posterior surface smooth, 

 bearing a single longitudinal series of setiferous tubercles. 

 Upper surface of brachium bearing a single row of small 

 denticles, posterior surface bearing two roughened keels ; 

 inferior surface smooth, with two rows of setiferous punctures 

 near the hind margin ; inferior surface separated from the 

 anterior surface by a few conspicuous denticles ; anterior sur- 

 face finely granular. Upper surface of the hand convex, as 

 in Eoeseli, and with anterior margin similarly rounded, covered 

 with a reticulated pattern composed of smooth irregular ridges, 

 which result from the confluence of rounded tubercles ; these 

 ridges may assume a definite longitudinal arrangement, which 

 imparts to the hand a subcostate appearance ; anterior (inner) 

 margin of the hand denticulated ; inferior surface proximally 

 smooth, distally sparsely denticulated, the denticles not 

 arranged in definite series. Fingers granular above and 

 below, all the segments of the palp sparsely pilose. 



Upper and lower surfaces of the femora of the legs some- 

 what coarsely granular ; anterior surface, those of the first 

 pair excepted, finely granular. 



Pectines not projecting so far as the distal margin of the 

 posterior coxaj; number of leeth thirteen.
