COLOSSENDEIDAE 



23 



C. gladah's, and serrated distally like those of C. frigida, C. megalonyx and C. scoresbii, 

 n.sp. (Fig. 7 e and/). 



Legs slender, without spines ; claw equal to or slightly shorter than propodus which 

 is only a little shorter than tarsus (see Fig. 8 b). 



Surface of body and limbs destitute of spines or spinules but uniformly covered with 

 minute setae.

Remarks. These specimens are most nearly related to C glacialis, Hodgson, but 

 differ from that species in the following respects: (i) they are of more slender build 

 without the spinules on body and legs characteristic of C. glacialis, (2) the tarsus is 

 shorter, the claw longer and there are no spines on the legs (cf. Fig. 8 a and b), (3) the 

 terminal joints of the palp are narrower, the sixth segment is twice as long as wide, the 

 seventh nearly as long as and the two distal ones rather longer than the sixth, the setae 

 on the palp are much shorter (cf. Fig. 4 c and d) ; (4) the principal spines on the ovigers 

 are thin, broadened and serrate distally, recalling those of C. frigida and C. scoresbii 

 (cf. Fig. 7 a-/and^); (5) the abdomen is shorter and broader.
