facial space. The colour of the cephalothorax is a deep reddish 

 brown ; the surface is finely rugulose, and furnished with a few coarse 

 hairs. 



The eyes are placed in two transverse and about equally curved 

 rows, forming a long narrow oval figure, occupying the whole 

 width of the fore part of the caput ; those of the fore-central pair 

 are the largest, and are seated on a tubercular prominence, being also 

 very nearly contiguous to each other ; those of each lateral pair (which 

 are rather widely removed from the four central eyes) are seated 

 on a strongish tubercle ; those of the hind-central pair form a line 

 rather longer than the fore-centrals, and are separated from each 

 other by a little more than a diameter's interval, an interval of 

 about 1^ diameter also separating each from the hind-lateral eye on 

 its side. 



The legs are very slender ; their relative length 1, 2, 4, 3 ; those 

 of the first pair very long, of the second pair rather shorter; those 

 of the third and fourth pairs very much shorter. They are fur- 

 nished with fine hairs, and each has three slender spine-like bristles. 

 Those of the two first pairs are of a reddish yellow-brown colour, 

 the two hinder pairs being pale dull yellowish, broadly annulated 

 with dark brown. 



The palpi are slender, of a pale whitish-yellow hue, excepting the 

 fore part of the radial and the digital joint, which are reddish 

 brown. 



The falces are strong, rather lighter-coloured than the cephalo- 

 thorax, a little divergent at their extremities, prominent at their 

 base in front, and furnished with very fine tubercles or granulations 

 on their outer sides. 



The maxillce are of normal form, and of a dark-brown colour ; 

 the labium is rather darker ; and the sternum is similar in colour to 

 the falces. 



The abdomen, looked at from above, is of an oval form, broadest 

 in front, and obtuse behind: in profile it is triangular. On the 

 upperside it is black, with a central longitudinal yellowish-white 

 stripe ; terminating short of the extremity in a triangular form, on 

 each side of this, but shorter than it, is a narrower longitudinal 

 curved stripe of the same hue ; and following each curved stripe are 

 two other short oblique stripes of the same colour and in the same 

 longitudinal line. The sides are reddish, marked obscurely with 

 several oblique pale stripes ; the underside between the spinners and 

 the extreme point of the abdomen is black, with a short longitudinal 

 pale stripe just beneath the point. Spinners short, of a pale whitish- 

 brown hue, and deeply imbedded in a circular kind of cavity at the 

 lower angle of the abdomen. The genital aperture has a small 

 slender, cylindrical, pale prominent process connected with it. 



A single example of this pretty species was contained in Mr. 

 Atkinson's New-Zealand collection,
