242 BRITISH TYROGLYPHm^E. 



texture of chamois leather, but covered with very fine 

 labyrinthine markings. 



Shape. Conical anteriorly, with slight indentations 

 for the reception of the first and second pairs of legs ; 

 very gradually and very slightly curved inward 

 between the second and third pairs of legs, but 

 becoming as wide posteriorly as anteriorly from the 

 continuation outward of the same slight curve ; pos- 

 terior margin rounded. 



Female. Rostrum blunt, the palpi showing plainly 

 at the side of the mandibles. Mandibles (PL VIII, 

 fig. 8) tridentate on each arm of the chela. There are 

 a pair of hairs quite close together springing near to 

 the median line a little anterior to the insetting of the 

 first pair of legs, and projecting anteriorly beyond the 

 proximal ends of the tarsi of the first pair of legs when 

 stretched out. A second pair of about similar length 

 further apart, but nearer the median line than the edge 

 of the body and about opposite the insetting of the 

 second pair of legs ; these hairs curve forward and 

 outward. A third pair spring from a little within the 

 edge of the body a short distance behind the second 

 legs ; the length of these hairs is nearly equal to the 

 width of the body ; they stand more outward than 

 forward. A fourth pair of hairs a little further back, 

 and of similar length, spring from about mid-distance 

 between the median line and edge of the body ; and 

 therefore do not project so far over the lateral edge of 

 the body as the third pair, although parallel to them. 

 A fifth pair, not much above half the length of the 

 fourth, spring from slightly under the body. A sixth 

 pair, inserted slightly within the edge of the body and 

 about over the coxa of the third leg, is longer than any 

 of the preceding ; it is three-quarters the length of the 

 entire creature. A seventh pair, about the middle of 

 the lateral edge of the body, is shorter rather more 

 than half the length of the sixth ; this is the last hair 

 which usually points at all forward. The eighth pair 

 is a little within the margin and as long as the sixth ;
