Although not quite adult, yet the very distinct markings and 

 colours of this Spider leave me no doubt whatever about its being 

 (as far as I am aware) undescribed. In form and structure there is 

 no marked departure from the ordinary generic type ; the sides of 

 the thoracic portion of the cephalothorax are deep black-brown, the 

 margins being yellowish ; the caput is yellow ; a continuation of this 

 colour, in a tapering or wedge-shaped form, runs backwards from the 

 occiput to the hinder slope of the thorax ; and a deep blackish-brown 

 band runs back from the hind central eyes, tapering to a point at the 

 central indentation where the thoracic segments converge. The 

 clypeus has two brownish maculse near its lower margin, one on 

 either side of the central point : the height of the clypeus equals 

 half that of the facial space ; it is a little impressed transversely 

 immediately below the eyes, from the slight prominence of the ocular 

 area. The eyes are in the ordinary position, on greyish-black 

 tubercular spots, and not very unequal in size ; those of the hiuder 

 row are not quite equally separated, the centrals being further from
