160 SUBANTARCTIC ISLANDS OF XEW ZEALAND. [Spiders and Opilinnes. 



The abdomen is a moderately broad oval. The spinnerets are 2- jointed, the 

 inferior pair stoutest, 1st joint conical, the 2nd hemispherical. The superior have 

 the 1st joint cylindrical, with the 2nd joint half as lon,o as the 1st, and conical. 



The crihellum is single, thin, and linear. 



The 4th pair of legs is barely as long as the 2nd. 



This species differs from the accepted limits of the genus in its wi(h'r cIvjh'US ; 

 the greater procurvature of the rear row of eyes, which makes the area of the median 

 longer than broad ; and in the single cribellum. This latter, however, I have found 

 before in some males of the genus. It is a true Amaurohius in other respects. 



The measurements (in millimetres) are as follows : Cephalothora.x, 7 mm. long, 

 5 mm. broad (3h mm. in front) : abdomen, 9 mm. long, 6 mm. broad ; mandibles, 

 3^ mm. long.

Badumna scylla, nov. sp. (Plate VII, figs. 3a-3c.) 



Cnlonr. — Cephalothorax orange, darker in the median and side lines and round 

 the margin. The upstanding hairs are dark brown. The eyes have orange rims, 

 with black centres. 



The mandibles are dark yellow-brown with brown hairs above, dark orange with 

 short white hairs underneath ; fangs yellowish-red ; basal muscle-spots yellow. 



The lip, maxillae, and coxae are yellow-brown, the lip having 2 dark-brown 

 streaks, 1 each side of the median line. The sternum is a dingy yellownsh-grey, 

 darker than the rest. The legs are yellow, with dark-grey rings. Palpi yellow. 



The abdomen above is black mottled with yellow, with brown upstanding and 

 pale-yellow downlying hairs. On each side of the median line anteriorly are broad 

 yellow patches to one-third of the length of the abdomen, and just in the middle a 

 yellow St.-Andrew-shaped cross. On the underside are 4 longitudinal yellow stripes, 

 reaching from the anterior to the posterior tracheal apertures, on a black ground. 

 The hairs brown, ujjstanding, and fine pale yellow. The spinnerets are dark brown 

 and the crihellum white. 



Ij 1 The cephalic part of the cephalothorax is raised up equally with the thoracic 

 part in the median area, whence it slopes steeply to the margin. 



The rear row of eyes are procurved, the tops of the laterals being on a level with 

 the bottom of the median. The latter are their diameter apart, and about twice
