Blackwall — S2)idei:s Captured in the Seychelles Islands. 5 



and metatarsi of the first and second pairs ; the fourth pair is the 

 longest, then the third, and the second pair is rather shorter than tlie 

 first ; each tarsus is terminated by two small, curved, minutely pecti- 

 snated claws, below which there is a small scopula. These parts have 

 a brownish-yellow hue, the legs being tinged with brown at the arti- 

 culation of the joints. The palpi are short, lighter coloured than the 

 legs, and the radial and digital joints are well supplied with pale 

 hairs. The abdomen is oviform, convex above, somewhat pointed at 

 the spinners, which are prominent, and is clothed with pale hairs ; 

 the upper part and sides are of a brown colour, the former being- 

 spotted with yellowish- white. A yellowish- white band, which curves 

 round the anterior extremity, and extends along the sides, projects 

 two streaks of the same hue from its inner margin, on each side, the 

 two posterior ones nearly forming a transverse band about a third of 

 its length from the spinners ; the under part is of a yellowish- white 

 -colour, with a transverse brown bar before the spinners ; and the sexual 

 organs, which are minute, have a dark reddish-brown hue. 



The male is smaller and much darker coloured than the female. 

 The palpi have a dark-brown hue, and the humeral joint has a pointed 

 process near its base, on the under side, which is curved downwards ; 

 the digital joint has an oblong oval form ; it is convex above, 

 -densely clothed with whitish hairs, compact at the extremity, with a 

 concavity at the base that comprises the palpal organs, which are 

 neither highly developed nor complex in structure, and are of a dark- 

 brown colour. 



[I feel no doubt but that this spider is the Attus luguhris of 

 Vinson (Araneides des lies de la Eeunion, &c., p. 50, PI. x., fig. 7), and 

 this latter species is certainly identical with the Attus variabilu of 

 the same author. The examples from which Mr. Blackwall's descrip- 

 tions were made have lost colour and lustre considerably, but the abdo- 

 minal pattern is quite distinct in both sexes. The humeral joint of the 

 male palpus (as noticed by Mr. Blackwall) is armed with the pointed 

 protuberance characteristic of the genus Heliophanus.]

 Length of an immature female, ^th of an inch ; length of the 

 cephalothorax, iV ; breadth, -oV ; breadth of the abdomen, -h^ ; length 

 of a posterior leg, -J ; length of a leg of the second pair, -^. 



The cephalothorax is long, broad and quadrate in the cephalic 

 region, immediately behind which it is constricted, and then tapers to 

 its base ; it is glossy, sparingly supplied with hairs, projects a little 

 beyond the base of the falces, and is of a brownish-yellow colour tinged 

 with red, particularly on the posterior half. The eyes are seated on 

 black spots, and the minute intermediate one of each lateral row is 

 nearly equidistant from the eyes constituting its extremities. The
