38 MR. H. R. HOGG ON SOME 



sternum. The latter is like the lower end of the sternnm in 

 Truenonyx, but without the narrow stem ; consequently the 

 operculum is brought much closer to the mouth-parts, as in 

 genera so far removed as Stylocellus Westw. The head of the 

 penis is bluntly triangular, and its upper and lower sheaths, as 

 far as can be seen when not extended, are terminated in a 

 transverse line. 



Tlie mandibles are shorter and weaker than in Trkenony.v ; the 

 first joint does not reach as far as the end of the eye-tubercle. 

 The pcd'pi also are short and weak, and are not longer than the 

 dorsal cn.ra,pace. 



The legs are fringed the whole distance along the femora., 

 patellfe, and tibife with long spines ranged on each side of the 

 I'espective joints. 



The measurements (in millimetres) are as follows : — 



Ceph. Ig. li, lat. U ; abd. Ig. 2|, lat. 2] ; mand. 1 ; palpus 2^ ; 

 1st leg 5, 2nd 8, 3rd 6^, 4th 8|. 



This species differs from T. pectivatiis Poc. in having a larger 

 number of projections along the sides of the eye-tubercle, in" 

 having a larger number of spinous tubercles on the rear segments, 

 and in being without the median row of larger tubei-cles on the 

 dorsal carapiace. 



I have four specimens, of which three are certainly males. 

 They were collected by Mr. T. Hall near the HoUiford River, 

 L. Wakatipu district in the province of Otago.

Genus Trijsnonyx Sor. 

 W. Sorensen in Koch & Keys. Die Ai^achn. Austr., Suppl. p. 58. 



This genus, being now restricted to those species in which the 

 eye-tubercle is marginal, includes, with new ones that 1 am now 

 vecoiding, onlj^ seven in number. These may be distinguislied as 

 follows : — 



a. Carapace coarsely granulated. 



n^ Transverse row of granules on carapace, and a pair of 



spinous tubercles at posterior end of same T. rapax S5r. 



S'. No spinous tubercles on carapace. 



a". Carapace cliocolate-hrovvn ; rear segments orna- 

 mented with round Hat orange spots, with a 



short bristle on each T. cocl-ayni, sp. n. 



h". Carapace deep brown ; a series of low tubercles, 

 I'ut no bright sjsots on rear segments. 



a. Distal end of tarsus elongated T. coriacea Poc* 



j3. Distal end of tarsus nodular T. aspera 'Poc. 



* Mr. Pocock (Ann. & Mag. Nat. Hist. May 1903, p. 41-5) refers to a species in 

 thi« section under the name of T. verrucosa. This 1 am unable to trace the origin 

 of, and he allows me to state that he was, he believes, intending to refer to the 

 species named T. coriacea.
