194 Mr. R. I. Pocock on new 
terior pair small, close to the edge of the sternum, the 
remaining two pairs represented by indistinct elongate naked 
areas extending from near the edge towards the centre of the 
sternum. 
Legs: third and fourth pairs stronger than first and second 
pairs; tarsi and protarsi of first and second pairs thickly 
and strongly spined on their margins, scantily hairy below ; 
tibie of the legs furnished with a few spines in the same 
position ; in the third leg the femur is enormously stout, 1ts 
width being about three quarters of its length; the patella 
thickly covered in front and above with stout short spines, 
forming a regular comb along the distal -border; the tibia 
also, which is much shorter than the patella, armed in the 
same way in front and above with two clusters of spines ; 
protarsus much thinner than the tibia, armed above with two 
series of spines and one long distal spine below; tarsus un- 
armed ; femur of fourth leg armed apically above and ante- 
riorly with a small cluster of spines; patella with a few 
spines intermingled with sete, tibia unarmed except for a 
few setiform spines below; protarsus armed with many long 
spines; tarsus unarmed; claws armed with one very long 
tooth, behind which on the third and fourth leg there is an 
additional spinule and one in front of it on the anterior claw 
of the first and second leg; the inferior claw long and strong. 
Palp with tarsal segment strongly spined from base to 
apex without and within; a number of spines, too, on the 
anterior aspect of the tibia and a few on its posterior aspect. 
Genital plate mesially thick, horny, and black. 
Spinners conical, the basal segment longer than the two 
distal segments, of which the apical is the shorter. 
This genus is most nearly allied to Cyrtocarenum, but 
certainly differs in the width of the ocular area and in the 
form of its sternal impressions.
