50 Transactions. — Zoology. 



The abdomen is ovoid, pointed posteriorly, resembles the cephalothorax 

 in colour and pattern ; the ventral surface is black, sparingly clothed with 

 short white hairs. The vulva consists of a large, narrow, somewhat circular 

 yellowish-brown hood, clothed with hairs, in the centre there is a somewhat 

 quadrate protuberance, of the same hue, with dark fovese at the anterior 

 extremity. 



Mountains above the Otira Gorge, Westland, A.T.TJ. 



Salticus compactus, sp. n. PI. xi., fig. 18. 



Length of a mature female 4 mm. 



The cephalothorax has a dull brownish-black colour, finely rugulose, 

 furnished with a few light hairs ; it is rounded posteriorly as far as the 

 hind-lateral eyes, from whence it is moderately constricted forwards ; 

 truncate in front ; the lateral margins are abrupt, slightly inclined inwards ; 

 the profile line ascends abruptly from the thoracic junction, then slopes 

 across the caput, forming a somewhat obtuse angle, with the hind-lateral 

 eye placed on the anterior side of the apex. The clypeus is clothed with 

 strong white hairs directed centrally, in height it equals the diameter of one 

 of the fore-lateral eyes. 



The ocular area is remarkably large, extending over the greater portion 

 of the cepahlothorax, whose greatest diameter is between the hind-lateral 

 eyes, intersecting the faint medial fovea ; the small intermediate eyes are 

 placed nearest to the fore-laterals ; the anterior row are fringed with orange- 

 coloured hairs on the lower side. 



The legs are moderately long, 1,4, 2, 3 ; the first pair is the most 

 robust, and does not differ much from the fourth in length ; the femoral 

 joints have a dark mahogany hue, the other joints a reddish amber colour, 

 palest at the extremities ; the armature consists of a few lightish hairs, fine 

 bristles, and spines, which are normal. 



The palpi have the lighter tints of the legs, and are furnished with 

 bristles and hairs. 



The falces are vertical, flat, rounded at the apices, armed with strong 

 teeth, bright chocolate brown, rugulose. 



The maxilla are broad, rounded, inclined towards the lip, which is semi- 

 circular ; these parts are dark brown, with light slightly recurved apices. 



Sternum ovate, posterior end broadest, black, furnished with a few coarse 

 ligbt hairs. 



The abdomen is a broad oval, convex, projects over the cephalothorax ; 

 dull black, finely rugulose, obscurely marked with oblique brown streaks, very 

 sparingly furnished with light hairs. The ventral surface has a lightish 

 hue, and is more thickly clothed. The vulva consists of a reddish brown, 

 moderately wide, nearly circular hood, the ends on the posterior side curved 

 inwardly, nearly dividing the crimson brown concave portions.
