212 DE. J. &. DE MAN ON THE PODOPHTHAIMOTJS 



margin of the buccal cavity anotlier and similar tooth is found 

 on the pterygostomian region, as in Cryptodromia tomenfosa, 

 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 is a 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 

 o£ 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.
