Spiders and OpiUone^.] SUBANTARCTIC ISLANDS OF NEW ZEALAND. 175 



Male. — Cephalic part yellow, the grey streaking on the sides and rear being 

 much less pronounced than in the female, though there are faint traces of it. The 

 mandibles are yellow ; the fangs yellow-brown ; sternum, lip, and maxillae yellow, 

 with fine brown hairs. Legs yellow, ringed with grey, with brown hairs and spines ; 

 bristles on the metatarsus grey. Palpi yellow. The abdomen on the upper side is 

 black-brown, slightly mottled with yellow, with pale yellow hairs ; underneath 

 yellow-grey and black, with similar pale-yellow hairs. Spinnerets dingy yellow-grey. 



Male and Female. — The raised-up part of the cephalothorax is rather narrow, 

 sloping steeply to the edges all round. The eyes of the rear row and laterals of the 

 front row form an oval ring, the front laterals lying nearly under the rear median. 

 The 2 quite small front median, their diameter apart, are just above the space 

 between the laterals. The 6 large eyes of the female are 1| times the diameter 

 of those of the male, and consequently nearer together. The maxillae, lip, and 

 sternum are as in M. kirki, above described, the sternum being convex. There 

 is a space between coxae ii and iii in both sexes, but in the male the rear coxae 

 are quite contiguous. The legs are long and fine, with about 6 pectinations on the 

 superior claws, and numerous long spines on the tibiae and metatarsi, with bunches 

 of spines at the end of the latter. There are 2 spines on the upper side of each femur. 

 The mandibles are as long as the cephalothorax is broad in front. They are kneed, 

 conical, and divergent, with 2 or 3 small and 2 larger teeth on the inner edge of the 

 falx-sheath, and 1 large between 2 small on the outer. The palpi are Ij times the 

 length of the cephalothorax, the tibial joint being equal to the patellar. 



The measurements (in millimetres) are as follows : — 



Female. — Cephalothorax, 2j mm. long, 2 mm. broad (Ijmm. in front) ; abdo- 

 men, 2 J mm. long, Ij mm. broad ; mandibles, Ij mm. long.

Besides being very much smaller, this differs from M. kirki in having legs 

 i and iv equal in length, instead of the 4th pair considerably the longer. The 

 palp 'is longer in proportion, the tibial .joint of same being equal to'^the patellar 

 instead^of longer. The pattern on the cephalothorax alone identifies it, and the 

 eyes are dull and dingy instead of bright topaz-yellow.
