Blackwall — Spiders captwed in the Seychelles Islands. 17 



The figure and description of this handsome species given by 

 il. Yinson are those of a young male, whose palpal organs -were not 

 developed, and which probably had to undergo its final ecdysis before 

 it arrived at maturity. 



As the female, though larger than the male, resembles it in colour, 

 I shall here briefly offer a few remarks upon it relative to such 

 particulars as have been omitted by AT. Yinson. The eyes are seated 

 on black spots, and the posterior ones of the lateral pairs are the 

 smallest of the eight. The maxillse are enlarged and somewhat 

 rounded at the extremity, and of a brownish-yellow colour. The lip 

 is semicircular, and slightly pointed at the apex ; and the sternum is 

 heart-shaped, with eminences on the side, opposite to the legs. These 

 parts have a brown colour ; the base of the lip, which is the darkest, 

 is tinged with red, and its apes has a brownish-yellow hue ; a 

 yellowish-white line, that tapers to its extremity, extends along the 

 middle of the sternum. The first and second pairs of legs are marked 

 with brown at the extremity of the joints, on the under side, and the 

 fourth pair is longer than the second. The abdomen has a brown 

 band, streaked longitudinally with dull yellow, extending along each 

 side, and the yellowish-white medial band on the upper part comprises 

 an obscure, pale-brown, longitudinal line : the branchial opercula 

 have a brown hue, and there is in connexion with the sexual organs a 

 prominent curved process, directed backwards, which is of a red- 

 brovm colour, its extremity being much the darkest.

The abdomen has a large conical protuberance situated near the 

 middle of the upper part, high above the spinners, which has an 

 obtuse prominence on each side of its extremity ; it is broader in tlie 

 middle than at the anterior part, which projects a little over the base 

 of the cephalothorax ; a black band, bordered by a white line, extends 

 along the middle of the upper part to the base of the conical pro- 

 tuberance, which is black in fi'ont, with a white spot on each side, 

 and of a yellowish-white colour, mingled with black, in its posterior 

 region, the apices of its terminal prominences having a yellowish- 

 white hue, and there are a few white spots at the base of the spinners; 

 the sides have a triangular form, and their colour is black, with pale 

 reddish and yellowish-broAvn intermixed, an angular wliitish mark, 

 whose lower limb is the longer, and whose vertex is directed back- 

 wards and downwards, being situated at the extremity of each ; the
