AUSTRALIAN OPILIONES. 35 



The dorsal abdominal part has a still paler median area, light 

 yellowish grey, narrower in front and broadening posteriorly to 

 a scolloped pattern near the rear end. This is bordered by a 

 dark brown streak on each side, separating the median area from 

 the briglit yellow-brown sides. 



The mandibles and 2^<^lpi a-i'e bright yellow, and the legs pale 

 yellow-brown, except the distal end of femora 3 and 4, which is 

 darker. 



The carapace and abdomen are both quite smooth and destitute 

 of granulation, as are also the mandibles, which are of the quite 

 short type, less than the length of the body. 



The coxje and vmder side of the abdomen are pale yellow- 

 brown, quite smooth, and the segmental divisions almost obliter- 

 ated, being just indicated by darker transverse streaks. 



The patellar joint of the palpi is slightly longer than the tibial, 

 both joints broadening ante rioiiy and being profusely covered 

 with short bristles. 



The genital operculum is thick and broad. 



The measurements (in millimetres) are as follows : — 

 • Ceph. Ig. 2, lat. U in front, 2^ behind; abd. Ig. 21, lat. 3; 

 maud. 3|; p^alpus 6;'lst leg 18, 2nd 42^, 3rd 19|, 4th 29. 



Four specimens, much shrivelled and without label, but from 

 New Zealand. Three are males with long mandibles and the n)ale- 

 shaped operculum, and one is a female with seemingly broadtr 

 and straighter operculum and short mandibles. Also one female, 

 collected on Mt. Algidus, Rakaia Gorge, South Island, l)y 

 Mr. T. Hall, to whom the species is dedicated. It is to his 

 efibrts that this large and valuable collection is mainly due.

 . The cephalic part of the carapace is bright yellow-brown. The 

 abdominal part is rather darker brown in the median area, pale 

 and dark mingled at the sides. The luider side is pale yellow from 

 the front to as far as the base of the genital operculum, brown on 

 the abdominal segments. The coxjb are pale yellow, with a dark 

 brown band on each at the end nea,rest to the trochanter. 



Tl)e legs are yellow, banded with brown. The mandibles pale 

 yellow, blotched with brown. The palpi yellow, banded with 

 brown on the femur and patella, more faintly on the tibial and 

 distal joints. 



The inandibles are of tlie short type, not so long as the body, 

 and, though covered with short bristles, are otherwise smooth. 



The carapace is wholly smooth, but there is a. short sjDine on 

 trochanter i. The eye-tubercle is nearly in the centre of the 

 cephalic region. The genital operculum is broad in front. 



The measurements (in millimetres, but legs mostly bi-oken) 

 are as follows : — 



Ceph. Ig. 2| ; abd. Ig. 3| ; mand. 3| ; palpus 5 ; 1st leg 31.
