The measurements (in millimetres) are as follows : —

 palpus 3^ ; 1st leg~5, 2nd 8, 3rd 5^, 4th 7|.

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 

 p.alpi and without the clear pattern on the back. They were all 

 gathered by Mr. T. Hall. 



The males are, as mentioned by Mr. Pocock, generall}^ more 

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



The wide sternum and well-formed lip above it are featiu-es 

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

 have not made them so in cons^ideration- of other resem.blaiices- 

 the species shows to the genus Tricenonyxr.

Following the limitations adopted by Loman and Pocock, we- 

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

 the ocula.r 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 tlie tarsal cla,w\s of the tliird 

 and fourth pairs of legs with short side claws springing from 

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

 following : —
