and more cylindric than the others ; surface of carapace in general 
granulate, (Plate 2, fig. 3). 
A row of conical tubercles across each abdominal segment. Anal 
scutum proximally with smaller granules and tubercles, distally with 
a number of larger tubercles, about five of which appear as dentations 
on the caudal margin, one at middle and two or three on each side 
of it. 
First coxae bent forwards at ends, the second slightly so. Third 
coxae but little shorter than the second. Coxa I in both male and 
female on caudal side above middle with two conical processes and at 
distal end on caudoventral corner with a longer process which is bent 
dorsad; along its anteroventral surface a row of tubercles the most 
distal of which appears at the anteroventral corner as a freely pro- 
jecting larger conical process; from anterior surface at distal end a 
long cylindrical process which bends dorsad close to surface and over- 
laps the end of a process springing from anterodorsal surface. A low 
broad process from distal end of coxa II near anterodorsal corner; a 
row of a few tubercles along anteroventral line and a similar one on 
third coxae. Coxa IV at distal end on mesal side with a low rounded 
process, (Plate 2, fig. 4-6). 
Spiracles clearly exposed. 
First joint of mandible strongly elevated above distad of the con- 
striction; with a transverse row of caudally projecting teeth or conical 
tubercles across upper border of caudal surface of the dorsal hump; 
dorsal surface of hump with fine teeth or granules; second article 
rather short and broad with a few hairs at distal end below (caudad) 
and more in front, (Plate 2, fig. 1). 
Pedipalps short, closely flexed ventrad and caudad, not crossed. 
Coxa subcylindric. Trochanter narrow at base, expanding distad, 
with a broad conical projection beneath. Femur strongly flattened 
from side to side, being abruptly very high immediately distad of the 
narrow base; a row of teeth along the middorsal line and a series of 
longer subeylindric, distally rounded processes along ventral line. 
Patella of usual form; bearing small setigerous tubercles above. 
Tibia strongly flattened from side to side, especially on ventral half, 
clavately increasing in height from base distad; with a number of 
small tubercles on dorsal surface proximad. Tarsus subcylindric, 
with a low thin keel from ventral surface at proximal end, (Plate 2, 
ive 12) 
Femora, patellae, and tibiae of legs I to III finely tubercular or 
granular, the metatarsi more abruptly so proximally and especially
