yellow, below darker, being mottled with brown which is most abun- 
dant on the fifth segment and is partially absent from the first. 
Carapace and first six segments of the abdomen smooth and shin- 
ing; seventh abdominal segment finely granular, (Plate 1, fig. 5). 
First segment of postabdomen equal in length and breadth, the 
second a little longer than wide. Dorsal and upper lateral keels of 
first segment of cauda finely granular, the granules on those of other 
segments fewer and weaker or essentially absent. Ventral median 
keel of cauda absent from first four segments, weakly developed on 
the fifth; lower lateral keels of fifth segment conspicuous, strongly 
granular, the lower lateral keels of the other segments obsolete. 
Ventral surface of the fifth segment conspicuously granular excepting 
at anterior end, that of the fourth segment with scattered granules, 
the venter elsewhere smooth. 
Marginal keels of femur of pedipalp smooth; tibia along posterior 
ventral edge with trichobothria eight in number, these arranged in 
two rows of four each; hand of chela thicker than the tibia, smooth, 
with a row of 8-10 trichobothria under the outer ridge. The lateral 
granules on the mesal surface of the movable finger remaining apart 
and distinct from the main row over entire length, eight in number in 
each row, (Plate 1, fig. 6). 
The distal lamella of comb abruptly much narrower than the proxi- 
mal ones so that the anterior edge appears indented at its beginning 
as in B. ehrenbergi. Teeth of each comb 28 in number, (Plate 1, 
fig. 8).
