Leg I. : femur i. 0-205 (0-129) ; femur ii. 0'182 (0-125) ; tibia 0-243 

 (0-088) ; tarsus I. 0-122 (0-065) ; tarsus ii. 0-114 (0-053) mm. 



Leg IV. : femur 0-494 (0-240), trochantin 0-190 ; tibia 0-414 (0-137) ; 

 tarsus I. 0-160 (0-080) ; tarsus ii. 0-144 (0-068) mm. 



Material. — I have examined a single female, collected in Stewart Island 

 (New Zealand) bj Mr. H. B. Kirk. 



Remarks. — This species differs from Olp. longiventer, Keys. (4. p. 50), 

 among other particulars by less long and slender palps, the femur being only 

 2"7 instead of distinctly 4 as long as wide, and the chela being shorter not 

 longer than the combined femur and tibia.

Cephalotliorax. — The eyes are placed on the lateral margin and the distance 

 of the first pair from the front margin is scarcely as long as their diameter. 

 The ceplialotliorax has a rather curious shape, as the hindmost fifth is pale 

 and not enclosed by the well-chitinised shield, the hindmost margin of which 

 is almost straight ; the whole cephalothorax is distinctly longer than wide, 

 but the cephalothoracic shield is as long as wide. The head is somewhat 

 narrow in front of the eyes, forming a short cucuUus, which has a median 

 incision in the front margin. No trace of transverse suture was observed 

 and the skin is smooth and polished with rather short hairs. 



Abdomen. — The long and slender abdomen, which has its tergites undivided, 

 has a curious appearance on account of the almost or complete absence of 

 sclerites from the first two tergites and the short but distinct third one. The 

 almost smooth tergal sclerites show trace of a transverse keel, along which 

 the fairly long pointed hairs are placed in white spots, well removed from the 

 hinder margin. 



Antennae (PI. 10. fig. 40). — The slender galea, which extends distinctly 

 beyond the terminal hair, has three branches. All the teeth of the serrula 

 exterior are squarely truncate and of almost equal length (fig. 40). The 

 fiagellum consists of three hairs without ramifications or with almost obsolete 

 teeth along the front margin of the first hair {cf. fig. 45) . 



Palps (PI. 10. figs. 41 &42). — The smooth ma.n7/ce are gradually attenuated 

 towards the end. The palps are smooth with the exception of the anterior 

 surface of the hand, which has a few granulations at the base of the fingers. 

 The hairs are moderately long and pointed. The trochanter, which is 1*4 

 as long as wide, is slightly convex anteriorly, a trifle produced posteriorly and 

 appears calyciform. The femur, which is 2-5 as long as wide, has a short, 

 fairly well-defined stalk and is of almost equal width throughout, with nearly 

 straight lateral outlines. The tibia, which has a rather short, well-defined
