212 DR. J. G. DE MAN ON THE PODOPHTHALMOUS 
margin of the buccal cavity another and similar tooth is found 
on the pterygostomian region, as in Cryptodromia tomentosa, 
Heller (Hilgendorf, Monatsb. Berlin. Akad. 1878, Taf. ii. fig. 5). 
The second antero-lateral tooth is situated in the middle between 
the external angle of the orbits and the cervical suture, and is 
slightly prominent, but obtuse. The third tooth isa little smaller 
than the second and subacute. A small tubercle occurs imme- 
diately behind the cervical suture; the postero-lateral margins of 
the cephalothorax are slightly convex; the abdomen is unarmed. 
The anterior legs or chelipedes are equal. On the upper surface 
of the wrist there are four tubercles, two in the middle, being 
longitudinal, oval, and parallel with one another; there are 
also two other prominences on its distal margin at the articula- 
tion with the hand. The internal angle of the wrist is slightly 
prominent. The upper margin of the hand has also four tubercles, 
one at the proximal end near the articulation with the wrist, one 
in the middle, and two close to and above the articulation of the 
mobile finger; these tubercles are also obtuse, and the one in the 
middle of the upper surface is longitudinal and oval. The outer 
surface of the palm is probably granular, but the granules present 
are wholly concealed under a close pubescence, which also covers 
the anterior legs. The fingers are smooth and glabrous, and meet 
along their whole inner margins, which are denticulated, the im- 
mobile finger having three or four equal teeth, whereas the mobile 
finger is more feebly toothed. 
The two succeeding pairs of legs are somewhat nodose at the 
distal ends of their propodites, and the last pair of legs are about 
once and a half as long as those of the penultimate pair. All 
these legs are covered with the same pubescence and are, more- 
over, a little hairy.
