MR, H. R. HOGG ON SOME 



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

 Tri<«;)iom/x, but without the narrow stem ; consequently the 

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

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

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

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

 ti-ansverse line. 



The mandibles are shorter niid weaker than in Tricenonyx ; the 

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

 The palpi also are short and weak, and are not longer than the 

 d orsal ca rapace . 



The legs are fringed the whole distance along the femora, 

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

 respective joints. 



The measurements (in millimetres) are as follows : — 



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

 1st leg 5, 2nd 8, 3rd 7) J, 4th 8|. 



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

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

 ha ving a larger number of spinous tubercles on the rear segments, 

 and in being without the median row of larger tubercles on the 

 dorsal carapace, 



I have four specimens, of which thi-ee are certainly males. 

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

 L. Waka.tipu district in the province of Otago. 



Family T R i N o N Y c h i D ^. 



Genus Tri^.nonyx Sor. 

 W. Sorensen in Koch & Keys. Die Arachn. 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 

 recording, only seven in number. These ma}" be distinguished as 

 follows : — 



a. Carapace coarsely granulated. 



rt^ Transverse row ot granules on carapace, and a pair of 



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



b\ No spinous tubercles on carapace. 



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

 mented vvitb round tl;it orange spots, with a 



short bristle on each T. cocTcayni, sp. n. 



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

 but no bright spots on rear segments. 



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



^. Distal end of tarsus nodular T. asfera Poc. 



* Mr. Pocock (Ann. & Mag. Nat. Hist. May 1903, p. 415) refers to a species in 

 this section under the name of T. verrucosa. This I 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.
