Measurements in mm.:-( 5 ) Total length 5'5 ; palpus 4 ; 1st leg 7, 2nd 10, 3rd 6, 4th 10. Loc. New Zealand: Auckland (J). A. Steel). T r i^e x o x y x a s p e r a , sp . n . Colour (dry) paler than T. coriacea. Shape of body much like that of the female of that species, the dorsal surface somewhat sparsely but coarsely granular. Ocular tubercle low, granular; free teigites with a row of subequal tubercles and some granules as well. Mandibles with spine on basal segment, and spiniform tubercles on second segment. Palpi much stronger and more strongly spined than in T. coriacea ; 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-fourth or one-third longer than the patella, smoother, armed with three pairs of strong spines and a smaller proximal one on the outer side; tarsus with four pairs of spines. Legs longer, femur 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. TriyEXONYX s u b l .e v i s , sp. n. (Text-fig. 84, D, p. 410.)

Dorsal scute and tergites almost smooth, minutely coriaceous but with scarcely a trace of segmental tubercles or granules; 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 |
