SUBANTARCTIC ISLANDS OF NEW ZEALAND. [Spiders and Opiliones. 



The legs are only moderately stout, and fine at the anterior ends. The claws 

 are strong, with about 9 pectinations on the superior. 



The abdomen is ovate, straight in front, and rounded at the posterior end, 

 with long bristly hair on the upper side, and rather short stiff hair on the under. 



The spinnerets are 2-jointed, the 2nd short and hemispherical on the inferior 

 pair, rather more pointed on the superior, with a broad colulus between the inferior 

 pair, which, however, meet above it. 



The measurements (in millimetres) are as follows : — 



Female. — Cephalothorax, 5j mm. long, 4 mm. broad (3 mm. in front) ; abdo- 

 men, 6^ mm. long, 4 mm. broad ; mandibles, 3 J mm. long (longer than patella 1).

There are numerous specimens from the Auckland and Campbell groups, all 

 certainly the same. Of fifty specimens sent from these two groups, one-half are 

 members of this genus, so that it would appear to be the most firmly established of 

 any in the locality. 



Rubrius falxiatus, nov. sp. (Plate VIII, figs. 4a-4rf.) 



The cephalothorax is yellow, quite smooth, the eyes a bright topaz. The 

 mandibles a darker orange, with paler basal muscle-spots. The fangs red, brown- 

 red at the anterior end. The lip and maxillae dark yellow. Sternum, legs, and 

 palpi yellow. Abdomen on upper side black, mottled with small yellow spots 

 anteriorly, and yellow backward - curving transverse stripes on black ground on 

 posterior half. Long upstanding brown hairs, and patches of flat white plumose 

 hairs or bristles. The underside is yellow. 



The convex cephalic part occupies the major part of the cephfdothorax, which is 

 as broad in front as in its widest part. The rear row of eyes is procurved, by the 

 width of a diameter, from in front, but nearly straight viewed from above, equal in 

 size, and equidistant by rather more than the breadth of their diameter. The front 

 row is straight, its laterals on a common protuberance with the rear laterals half 

 their diameter distant. It is shorter in length than the rear row by the width of
