circular form, and there is scarcely any elevation in front of the 

 thoracic indentation. The profile line of the cephalothorax forms 

 an almost even curve in front of the thoracic indentation ; the 

 eyes occupy a rather broader transverse area, but their general 

 position and relative size are very similar to those of C. thoracica. 

 The legs are not quite so strong ; the metatarsi of the two 

 anterior pairs are longer, the tarsi narrower and more cylindrical : 

 those of C. thoracica being broader and of an oval form, and the 

 metatarsi and tibiae equal in length, while in the present species 

 the metatarsi are longer than the tibiae. In the present species 

 also the colour of the tarsi and metatarsi of the first two pairs 

 is a clear yellow, and the spines beneath the tibiae and meta- 

 tarsi differ a little in number and strength. The vertical spine in 

 front of the fore-central eyes is closer to them than in C. thoracica, 

 and the spine-like bristles on the abdomen are tapering in form and 

 less coarse. The bristles at the apex of the labium are several of 

 them dentiform.

It is possible that this spider may be only a small example of the 

 last species, C. affinis. It agrees with that spider in the cephalo- 

 thorax being longer than broad, and it has no elevation in front 

 of the thoracic indentation. The eye-area, however, appears to be 

 shorter in its transverse measurement and broader from back to 

 front, and the surface granulations, from the eye area to the hinder 

 extremity, are almost obsolete along a broad tapering central band ; 

 and the space between the lateral pair of eyes on each side is much 

 larger than in either of the foregoing species. The colour of the legs 

 is a uniform dull yellow-brown, excepting the femora, w r hich are of a 

 darker hue. At the apex of the labium are some longer tapering 

 bristly hairs, and behind them several small short dentiform spines. 



The armature of the two first pairs of legs is very like that of 

 the other species, the tarsi are more like those of C. thoracica, and 

 the form and structure of the palpi do not appear to present any 

 reliable difference. The abdomen is covered pretty thickly with 

 short curved strongish mostly slightly tapering spine-like hairs. 



I have thought it best, at any rate for the present, to record this 

 as a distinct species, though a longer series of the group can alone 

 determine whether it may not belong to a species in which there is a
