1873.] GENERA AND SPECIES OF ARANE1DEA. 121 



diameter or rather more, and they are rather in advance of the 

 straight line formed by the fore lateral eyes : behind the fore 

 centrals, and forming with them a quadrangular figure whose hinder 

 side is considerably longer than its fore side, are the two eyes which 

 form the second row ; these are exceedingly minute and very difficult 

 to see even with a lens ; and behind them are the two eyes forming the 

 third line ; these are rather nearer together than the fore laterals and 

 considerably less in size than those, but a good deal larger than the 

 rest ; the length of the line which they form is more than double of 

 that formed by each lateral pair ; the two eyes of the second row 

 are about equally distant from those of the first and third, and each 

 of them forms the apex of an isosceles triangle with the base formed 

 by the two lateral eyes nearest to them. 



The leys are moderately iong but rather slender ; those of the first 

 and second pairs are much longer than those of the third and fourth, 

 the second being rather the longest, and the third rather the shortest. 

 Their colour is pale yellow, the femora of the first two pairs being 

 tinged with orange-brown, and having a broad longitudinal deep- 

 reddish-brown stripe throughout their length both before and behind. 

 They are furnished with hairs and longish slender spines ; and each 

 tarsus terminates with two claws. The falees are short, strong, ver- 

 tical, and subcorneal in form, and rather darker in colour than the 

 cephalothorax. The palpi are short, slender, and similar to the 

 legs in colour. The maxilla and labium do not differ in form from 

 those of this genus in general ; and their colour, with that of the 

 sternum, is dark yellowish brown. 



The abdomen is of a short oval form, very convex above, and rather 

 broader behind than before, where it projects forwards just enough 

 to fit on to and cover the hind slope of the cephalothorax. It is 

 sparingly clothed with hairs ; and its colour is palish yellow, marked 

 on the upperside with four large black patches, which leave the yellow 

 ground-colour in the form of a cross ; the sides are also each marked 

 with a strong black patch, each patch meeting the other across the 

 underside of the abdomen a little way from the spinners ; the black 

 patches on the upperside vary in extent, in some examples being 

 almost wholly confluent. 



The adult male is rather less in size than the female ; but the first 

 and second pairs of legs are longer, and the femora are suffused with 

 dark reddish yellow-brown, the tibiae also being bright red-brown. 

 The palpi are short, not strong, but of a dark reddish-brown colour, 

 except the cubital joint, which is yellow ; the radial joint is of the 

 same length and strength as the cubital, being broadest in front, and 

 having a not very large bluntish pointed apophysis from its extremity 

 on the underside ; the digital joint is oval, pointed at its extremity, not 

 very large, but exceeding in length that of the radial and cubital to- 

 gether. The palpal organs are neither prominent nor complex, ap- 

 parently consisting of a flattish round corneous lobe, with a pointed 

 black spine issuing from near their inner extremity. The abdomen 

 of the male has the upperside covered with a stoutish coriaceous 

 shining shield clothed with a few small bristles, the sides and hinder
