There are three females from the Holliford River and one 

 young from Mt. Remarkables, L. Wakatipu. One from Mt. 

 Oakden ; also six specimens from Paradise, L. Wakatipu, of which 

 four are apparently males, with more prominent spines on the 

 pa.lpi and without the clear pattern on the back. They were all 

 gathered by Mr. T. Hall. 



The males are, as mentioned by Mr, Pocock, general!}!^ more 

 constricted in the cephalic part of the carapace than the females. 



The wide sternum and well-formed lip above it are features 

 which might almost be held to be of generic importance, but I 

 have not made them so in consideration of other resemblances 

 the species shows to the genus Tricenonyx.

 Following the limitations adopted by Loman and Pocock, we 

 may assume that the species to be attributed to this genus have 

 the ocular tubercle rising at a short distance from the front 

 margin of the carapace, that it is smooth and rather low and 

 without any prominence thereon ; the carapace itself smooth, the 

 sternum in both sexes narrow, and the tarsal claws of the third 

 and fourth pairs of legs with short side claws springing from 

 near the base of the median claw. On this basis we have the 

 following : —
