404 MR. K. I. POCOCK ON SOME [Dec. 2, 



cesses of the second pair of legs longer and more pointed, and the 

 spines on the palpi stronger. 



Measiu^ements in mm. :— ( $ ) Total length 5-0 ; palpus 4 ; 1st 

 leg 7, 2nd 10, 3rd 6, 4th 10. 



Log. New Zealand: Auckland {D. A. Steel). 



Tri^nonyx aspera, sp. n. 



Colour (dry) paler than T. coriacea. Shape of bodi/ much like 

 that of the female of that species, the dorsal surface somewhat 

 sparsely but coarsely granular. Ocular tubercle low, granular; 

 free tergites with a row of subequal tubercles and some granules 



as well. - . .„ 



Mandibles with spine on basal segment, and spmitorm tubercles 



on second segment. 



Palpi much stronger and more strongly spined than m T. cori- 

 acea ; femur convex above, and armed with about four spines 

 and some tubercles, some tubercles externally, three long spines 

 beneath externally and one smaller internally, two on the inner 

 side distally ; patella with one or two tubercles, and one internal 

 and one external spine; tibia about one-fotu-th or one-third 

 lono-er than the patella, smoother, armed with three pairs of 

 strono- spines and a smaller proximal one on the outer side; 

 tarsus with four pairs of spines. Legs longer, femui' of 1st armed 

 above and below with strong tuberculiform spines, a few on the 

 tibia also ; tarsal segments 3, 13, 4, 4; the distal portion of the 

 protarsus constricted to form a short spherical or nodular piece, 

 quite different from the elongate subconical piece of T. coriacea. 



Measurements in mm. :— Total length 5 ; of palpus 5 ; 1st 

 leg 8, 3rd 7-5, 4th 12. 

 Loc. Australia. 



Tri^nonyx subl^vis, sp. n. (Text-fig. 84, I), p. 410.) 



Colour brownish ; legs variegated with yellow. 



Shape of body in profile intermediate between the male and 

 female of T. coriacea, but the ocu.lar eminence not so far forwai-d, 

 its anterior surface sloping backwards and upwards from a little 

 behind the anterior edge of the carapace. Dorsal scute and tergites 

 almost smooth, minutely coriaceous but with scarcely a trace of 

 segmental tubercles or gTanules ; no tubercles near the fore part 

 of the cephalic area, merely the normal median spines. Sterna 

 with the transverse row of tubercles nearly obsolete. 



Mandibles with basal segment very long, subcylindrical, at 

 least four times as long as broad, with a small posterior dorsal 

 distal tubercle ; second segment with a series of tubercles ending 

 in one longer spine in front. 



Palpi long and powerful ; trochanter with a few short spines 

 above and one long spine below; femur convex above, armed above 

 and internally with dentiform tubercles, one on the inner side 

 being spiniform, beneath with one long basal spine and some 

 smaller spines or tubercles ; patella with one inner spine ; tibia
