174 SUBANTARCTIC ISLANDS OF NEW ZEALAND. [Spiders and Opili^es. 



The Up is as broad as long, straight, broad, and slightly hollowed on the front 

 margin, the sides rounded to the smaller base. The lip is half the length of the 

 maxillae, which slightly converge over it. From the anterior end, where they are 

 straight for a short distance from the troncature, they are rounded to the base, where 

 they are narrowest. The sternum is a broad shield-shape, straight in front, and 

 narrowing to a point at the rear, where it separates the 4th pair of coxae. The 

 1st and 2nd pair of coxae are contiguous, but separated by an interval from the 

 3rd pair. The coxae of the 4th pair are broader than any of the others, and separated 

 by a fourth of their width. 



The legs are moderately strong, tapering to the ends, with long stout spines : 

 1 above, on the femora ; 3 pairs below tibia i ; 2 pairs below metatarsus i ; and 

 3 pairs below, 3 at the sides, and 3 above on metatarsus iv. The claws are long 

 and strong, with 8 pectinations on the superior pair, and 1 near the base of the 

 inferior. 



The abdomen is ovate, pointed at the posterior end, with downlying short hairs 

 all over. The inferior spinnerets are conical, 2-iointed, the 2nd short and hemi- 

 spherical, one-third of their diameter apart, with a small colulus in front. The 

 superior pair are cylindrical, with a similar short 2nd joint. 



The measurements (in millimetres) are as follows : Cephalothorax, 4j mm. 

 long, 3j mm. broad (2 mm. in front) ; abdomen, 6j mm. long, 4 mm. broad ; 

 mandibles, 2 mm. long. Palpal tibia longer than patella. 



One female (not quite adult), from the Snares Islands. 



This solitary female is not quite through her last moult, but it is interesting to 

 find two species of this genus on the one small island, so I have described it and 

 named it after Professor H. B. Kirk, who discovered it. 



Myro ovalis, nov. sp. (Plate VIII, figs. 6a, 6i.) 



Female. — Cephalic part of cephalothorax yellow-grey, with a dark-brown median 

 longitudinal stripe, and 2 fainter curved brown stripes at the sides, reaching from the 

 rear row of eyes to the rear of the cephalothorax. On the sloping sides of the cephalic 

 part, and on the median area of the thoracic, are transverse dark-grey mottled stripes. 

 The lower half of the sides of the thoracic part are pale yellow. The eyes are dark 

 yellow with black centres, and there are long brown bristles in the eye-area. The 

 abdomen has a broad black median stripe at the anterior end, with yellow stripes 

 on each side of it ; beyond these, mottled yellow and brown. There are patches of 

 white plumose hairs on the posterior half. The spinnerets and epigyne are yellow. 

 The legs yellow, ringed with grey on the femora, tibiae, and metatarsi. The palpi 

 yellow, without atripes.
