The sternum is oval, nearly black. 



The abdomen is oval, finely rugulose, transversely marked with indistinct 

 brown and black streaks, thinly clothed with hairs of a similar shade to 

 those of the cephalothorax ; the sides and ventral surface are darker ; two 

 broad yellowish bands converge from above the branchial opercular round 

 to the spinners, which are pale brown. Tbe vulva consists of a prominent, 

 short, broadly-tapering, wrinkled, reddish process, with a large orifice at 

 the extremity. 



Karaka, Auckland, A.T.U. 



Salticus alpinus, sp. n. PI. xi., fig. 16. 



Length of an adult female 6 mm., and of an adult male 7 mm. 



The cephalothorax is somewhat quadrilateral, rounded posteriorly ; 

 moderately depressed above ; it is a dull black ; sparingly clothed with pale 

 yellow, coppery-yellow, and black hairs, forming a tabby-like pattern ; the 

 profile line ascends with a moderate curve from the thoracic junction, 

 sloping off anteriorly at the caput ; medial fovea shallow. The clypeus is 

 furnished with long white hairs, and its height is about half the diameter of 

 the fore -lateral eyes. 



The ocular area is nearly as long as broad ; fore- and hind-lateral eyes 

 equal ; small intermediate eyes equidistant between them. 



The legs are moderately robust, relative length, 4, 1, 2, 3, fourth and 

 first nearly equal ; they are tinted with light brown and black annul i, 

 clothed with black and white hairs ; the armature of the first and second 

 pairs consists of the usual double row of six spines on the inferior surface 

 of the tibiae, and of four on the metatarsi ; the femoral joints of the third 

 and fourth pair have two long bristle-like spines on the superior surface ; 

 one spine on the tibiae, six at the end of the metatarsi ; claws strong, curved, 

 pectinated. 



The palpi have a fulvous tinge, and are clothed with white hairs. 



Thefalces are vertical, convex, moderately broad, pale brown. 



The maxilla; are broad, obliquely truncated, inclined towards the lip, 

 which is semicircular, pointed ; these parts have a light brown colour. 



The sternum is oval, black. 



The abdomen is oval, rises with an inward curve from the pedicle, is 

 pointed posteriorly ; in colour and markings it resembles the cephalothorax, 

 but it is more thickly clothed with hair; the under side is light brown, 

 sparingly furnished with short light hairs ; a prominent medial ridge 

 extends from the genital organ to the spinnerets, which are moderately 

 long. The vulva is a simple hood-like, greenish-brown prominence, con- 

 cave within.
