each other than each is from the lateral on its side ; those of each 

 lateral pair are bright pearly white, placed a little obliquely, con- 

 tiguous to each other, and the largest of the eight ; those of the 

 fore central pair are the smallest, and nearly, if not quite, contiguous 

 to each other. 



The legs are rather strong, but not very long ; their relative 

 length is 1, 2, 4, 3 ; they are of a clear pale yellow colour, di- 

 stinctly banded with dark brown and furnished sparingly with hairs 

 and about the usual number of longish black spines. 



The palpi are similar in colour and markings to the legs ; and 

 from the fore extremity on the upperside of each of the cubital and 

 radial joints is a long, strong, black, slightly curved, tapering bristle ; 

 several smaller ones are also on the digital joint. 



The falces are long, rather slender, slightly diverging, and simi- 

 lar to the legs in colour. 



The maxillce, labium, and sternum are dark-coloured, the two 

 former being the lightest. 



The abdomen is of ordinary form, very convex above and project- 

 ing over the base of the cephalothorax ; the ground-colour is of a 

 dark leadenish hue, marked with black patches and markings, the 

 sides and upper surface being pretty thickly and rather symmetri- 

 cally covered with bright white cretaceous spots ; some of these 

 form slightly oblique lines on the hinder part of the sides, and others 

 a sort of horizontal cincture on either side of the fore half ; others, 

 again, form a broken horizontal band along the lower part of each 

 side. The general character and disposition of the abdominal mark- 

 ings bear a near resemblance to that of L. leprosa (Ohl.) ; but the 

 markings and colours of the cephalothorax distinguish it from that 

 species at a glance, as well as the distinctly annulated legs. 



A single example was contained in the St.- Helena collection last 

 received from Mr. Melliss. 



LlNYPHIA TRIFIDIDENS, Sp. D. 



Adult male, length 3 lines. 



This very distinct Spider has the cephalothorax of ordinary form, 

 but rather flattened, and, looked at in profile, it presents a straight 

 line rising gradually from the hinder slope (which is itself very 

 gradual) to the eyes ; its colour is yellow ; a broad, dark brown, 

 well-defined band runs along each side, converging and almost 

 uniting at the hinder slope, and generally meeting in front above 

 the falces ; this band leaves a rather narrow, but distinct, lateral 

 marginal stripe on each side : along the centre of the cephalothorax 

 a tapering dark-brown band runs back from the eyes to the hinder 

 slope, where it ends in a point, and where the junction of the caput 

 and thorax are marked by a strong longitudinal depression. 



The eyes are similar in their relative size and position to those of 

 L. albimaculata : the clypeus is slightly impressed immediately 

 below the eyes, and rather prominent thence to the lower margin ; 

 its height exceeds half that of the facial space. 



The legs are long, tolerably strong ; and their relative length is
