Show one-third longer than patella, with three long internal and two long external spines in addition to some smaller ones between and beyond the latter ; tarsus with three internal and three external spines, the proximal external small; claw longish and slightly curved. Coxa of palp and of 1st leg bispinate in front; coxa of 1st and 2nd legs tubercular, the latter externally spinate; remaining coxse nearly smooth, some tubercles on the posterior border of 3rd and 4th. Maxillary process of 2nd leg (text-fig. 84, D) double, consisting of a large quadrate tubercular process in addition to the normal process. Remaining segments of legs not spined, femora of 1st and 2nd at most tubercular; tarsal segments 3, 10 or 11, 4, 4; distal extremity of protarsi elongate, subconical. Measurements in mm.:-Total length 6 ; palp 8 ; 1st leg 10, 4th 14. Loc. West Taieri Bush, Otago, New Zealand (./. V. Jennings). In a young specimen of this species (3'5 mm. long) the tarsus of the 1st leg is bisegmented, that of the 2nd bisegmented with merely indications of subsegmentation, those of the 3rd and 4th trisegmented, the distal segment of the 4th showing faint signs of subdivision; the sternum is more like that of Adceuvi in shape. The known species of the genus from the Australian Region may be tabulated as follows :- a.
