 Tlie type species, sent by Dr. Brown from Hill Grove, 

 N. 8. Waies. 



MONOXYOMMA HENDEI, sp. n. (PL III. figS. 10 Cl-d.) 



Colour. The cephalic part is yellow-brown smirched with black- 

 brown, chiefly at the sides. The thoracic part and segments 

 almost wholly black-brown. The mandibles yellow-brown with a 

 slight network of black, and the palpi the same but tlie network 

 heavier. The under side of the carapace is very similar, yellow- 

 brown and black being mixed up without much semblance of 

 pattern. On the segments, however, the two colours are in 

 transverse bands. On the legs the same mixture occurs, the pale 

 being more in the joints. On the femur and tibia the two colours 

 appear in longitudinal bands. 



The median area of the carapace is slightly convex, this part 

 being circumscribed by a ridge in front, and at the sides with a 

 flat streak between it and the margin. The surface is coriaceous, 

 without spines or tubercles, except as below, either thereon or 

 projecting from the margin. The eye-tuhercle is situated on tlie 

 inner side of the ridge above mentioned ; it is conical and rather 

 tall, with the horn-shaped projection from its highest point bend- 

 ing slightly forward. This is about the same height as the lower 

 tubercle, from which it springs. Near the posterior end of the 

 carapace there is a lai^e bifid tubercle in the middle line, with 

 two transverse rows of small single ones, each with a bristle in 

 the middle, between it and the first of the segments. 



On each of the three abdominal segments is a row of similar 

 warty tubercles, rather larger than the above, each with a short 

 bristle. 



The mavdihles and paljn are fairly long and strong. On the 

 femoral joint of the latter are two longitudinal rows of quite 

 small spines ; on the tibial and distal joints the usual longer 

 spines. On the trochanter, femur, patella, and tibia of all legs are 

 rows of small warty tubercles with short spines, and similar but 

 smaller on the coxee. 



The measui'ements (in millimetres) are as follows : — 



Total lenoth 2|, breadth 2; mand. 2; palpus 4; 1st leg 6|, 

 2nd 9|, 3rd>, 4th 9|. 



One male from Hende's Ferry, Central Westland, N.Z., which 

 1 have named after Mr. J. W. Hendfe, the collector. 



MOXOXYOMMA TUBERCULATUM, Sp. n. (PI. III. figS. 11 a-C.) 



Colour. Males : a uniform dark yellow-brown over whole of 

 carapace. The posterior edge of each rear segment is distinctly 

 marked out by a pale transverse line ; the mandibles and palpi
