rear side-eyes about the same diameter as front middle. Whole 

 eye-space broader than long ; an oval tubercle between the median 

 and side pairs of front row of eyes has long bristles curling back- 

 wards. 



The lip is broader than long, almost triangular, with a small 

 triangular process at the apes, but without spines. The 

 maxilla? are divergent, hollowed at base round the lip ; rather 

 thickly bespined at the basal part. The falx-sheath has six large 

 teeth on the inner edge. Patella hi. lias a thick row of spines on 

 the anterior side. 



The abdomen is oval, rounded at the sides.

Besides its larger size, this differs from L. Koch's /. heha, from 

 Ovalau, in having the sides of the lip more sloping, the second, 

 third, and fourth pairs of legs longer in proportion, and both median 

 pair and laterals of front row of eyes respectively nearer together. 



Subfamily Avicfiaeiinx 



This subfamily, which contains all the largest members of the 

 Alviralornorphse, is characterized by being without both the third 

 claw and rastellum. Of the ten groups into which M. Simon 

 divides it, we are only concerned with two, the Ischnocolea 1 and 

 Selenocotmiea ; and if Mr. Pocock's supposition be found correct, 

 that after examination of more specimens of the former, they may 

 possibly all prove to be the young of other genera, we shall have 

 only about two genera, both foiling into the latter group. So far 

 no specimens have been recorded from New Zealand. 



The groups may be characterized as follows : — 



Having no stridulating organs. Scopulae of all tarsi divided.
