the lateral pairs of eyes is another, shorter, erect, rather slender, 

 bhnit-pointed, somewhat nipple-like eminence. The lower fore corners 

 of the clypeus are prominent. The colour of the cephalothorax is 

 pale whitish straw-colour, marked and clouded iu a somewhat 

 radiated form, on the sides, with brownish yellow ; it is clothed 

 with longish, pale, slender hairs ; and from the middle of the summit 

 of the central ocular eminence issue two longish, black, curved and 

 almost contiguous black bristles. 



The eyes are small ; those of the central group (four in number) 

 form a square on the front of the upper extremity of the middle 

 eminence ; those of each lateral pair are contiguous to each other on 

 the outer side of the summit of the lateral eminences, and are widely 

 removed from the middle group. 



The legs are neither very long nor strong ; those of the first and 

 second pairs differ but little in length, though perhaps the second pair 

 are slightly the longest, and the third pair are the shortest. They 

 are of a straw-yellow colour, semiannulated with brown, and clothed 

 with longish fine hairs. 



The palpi are similar in colour to the legs, and have a single 

 curved pectinated claw at their extremity. 



_ The falces are moderately long and strong, perpendicular, and 

 similar in colour to the palpi. 



The maxillce and labium are like those of A. trispinosa in form, 

 and are similar to the legs in colour. 



The sternum is of a somewhat triangular shape ; it is of a yellow- 

 ish colour, clouded with brownish in the middle, and marked witii a 

 black spot opposite to the basal joints of the second, third, and fourth 

 pairs of legs. 



The abdomen is large, very short, subtriangular, or somewhat heart- 

 shaped, extremely convex above, and projects considerably over the 

 base of the cephalothorax. On the upperside are some not very large, 

 bluntish, conical protuberances ; two of them are in a straight trans- 

 verse line, wide apart towards the fore margins ; the rest, eight in num- 

 ber, are arranged in a somewhat circular group at the posterior ex- 

 tremity. The upperside is of a dull sooty hue, mapped out into rather 

 roundish-angled patches of various forms and sizes, which are divided 

 from each other by clear and intersecting straw-yellow stripes ; 

 most of these patches have a central blackish spot on the fore part ; 

 and from each of the three immediately iu front of each of the two 

 foremost conical protuberances rises a long, erect, somewhat lanceo- 

 late black bristle, there being also several others of the same kind 

 on the sides and hinder part ; the patches above described are almost 

 obsolete on the middle and hinder part of the upperside, which are 

 then of a plain straw-yellow colour. The underside is suffused with 

 yellow-brown ; the hinder slope (?. e. the part between the protu- 

 berances at the hinder extremity and the spinners) and sides are 

 streaked vertically with pale yellow-brown lines. 



An adult female of this Spider was received from Paramatta (Aus- 

 tralia), where it was found by Mr. Barlow, and sent to me by my 

 kind friend Mr. Frederick Bond several years ago. I have also very
