36 REV. O. p. CAMBRIDGE ON NEW ARANEIDEA. [Feb. 5, 



height of the clypeus being half that of the facial space. The fore 

 central pair of eyes are separated from each other by 2 diameters' 

 interval and from the fore laterals by 1^ diameters; the latter are 

 largest of the eight, and (looked at from in front) form a curved row 

 whose convexity is directed upwards ; the hind lateral and hind cen- 

 tral eye, on each side, are contiguous to each other in a transverse 

 line, the four forming the ends of a very nearly straight row, rather 

 longer than anterior row, the hind centrals being the largest. The 

 centre of the ocular area, and reaching to a little way behind it, is 

 furnished with strong bristly hairs directed forward. 



The legs are short, very strong, 4, 1,3, 2, similar in colour to the 

 cephalothorax, furnished with hairs, and numerous short strong spines 

 near the sides of the tarsi and metatarsi of the first and second 

 pairs ; these spines, however, are very difficult to see, owing to the 

 density of the hairs on those parts ; there is, however, no scopula, 

 and the superior tarsal claws are (apparently) devoid of denticula- 

 tions. 



The /rt/ces are massive and about | of the length of the caput. 

 They are similar in colour to the cephalothorax and densely clothed 

 with short hairs excepting a large patch near the base in front, and 

 near their extremities are numerous short tooth-like spines. 



The palpi are similar in colour and armature to the anterior 



The maxillcB are strong, subcylindrical, with a strong prominent 

 conical point at the extremity on the inner side ; at the base on the 

 inner side of each maxilla is a short curved row of several dentiform 

 spines similar to some others at the apex of the labium. 



The labium is small, about equal in length and breadth at the 

 base, which is transversely curved, the convexity of the curve directed 

 backwards ; the base fits into a corresponding hollow in the sternum 

 on a kind of inverted subconical base marked in the sternum by a 

 distinct indentation. It is roundish-pointed at the apex, where 

 there are five short dentiform black spines. 



The sternum is large, triangular, a little broader at the base or 

 hinder end than long ; the base, however, being rather angulate, and 

 not rectilinear. It is similar in colour to the thorax, the labium 

 being of a deeper hue. 



The abdomen is short-oval, very convex, of a mouse-colour, clothed 

 with very short hairs. The spinners are short ; the superior pair 

 strong, and 3-jointed ; the inferior pair are much smaller and con- 

 sist of one joint only. A little way in front of the inferior spinners 

 are two small transverse slits or openings, doubtless the orifices of 

 tracheal organs. 



Two of these spiders, received from Natal along with their trap- 

 door nests, lived for some time in the Gardens of this Society ; 

 one is still living there ; the other died, and its remains, from which 

 the above description has been made, were sent to me by Mr. 

 Arthur Thomson along with a rough sketch of the upper part of 

 the nest, the lid of which (of the cork type) can just be covered 

 with a penny -piece.
