The sternum is oval, nearly black. 
The abdomen is oval, finely rugulose, transversely marked with indistinet 
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 opereular round 
to the spinners, which are pale brown. The 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, 8, fourth and 
first nearly equal; they are tinted with light brown and black annuli, 
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 tibiæ, 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 tibiæ, six at the end of the metatarsi ; claws strong, curved, 
pectinated. 
The palpi have a fulvous tinge, and are clothed with white hairs. 
The falces are vertical, convex, moderately broad, pale brown. 
The mazille are broad, obliquely truncated, inclined towards the lip, 
which is semicircular, pointed ; these parts have a light brown eolour. 
The sternum is oval, black. 
The abdomen is oval, rises with an inward eurve from the pediele, 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.
