of the same hue parallel to each lateral margin. The falces are 

 powerful^ conical_, vertical^ armed with teeth on the inner sur- 

 face, and are of a yellow-brown colour tinged with red at the 

 extremity. The maxilla? are short, straight, and broadly rounded 

 at the extremity; and the lip is semicircular, but somewhat 

 pointed at the apex. These parts are of a dark-brown colour, 

 that of their extremities being yellowish-white. The sternum is 

 heart-shaped, pointed at the extremity, and has prominences on 

 the sides, opposite to the legs ; it is clothed with hoary hairs, 

 and has a yellowish-brown hue, the medial line being the palest. 

 The legs are robust, provided with hairs and spines, and are of 

 a brown colour, with annuli of a darker hue ; the first pair is 

 the longest, then the second, and the third pair is the shortest; 

 the tarsi are terminated by claws of the usual number and struc- 

 ture. The palpi resemble the legs in colour, and have a curved, 

 pectinated claw at their extremity. The figure of the abdomen 

 is [somewhat quadrilateral, but the sides are rounded, and the 

 anterior is broader than the posterior extremity ; it is clothed 

 with short hairs, projects over the base of the cephalothorax, 

 and has two prominent tubercles on each side, and two large, 

 parallel, obtuse ones situated above the spinners; the upper 

 part, on which there are numerous circular glossy convexities, 

 of various dimensions, in bas-relief, is of a yellowish-brown 

 colour, an obscure, strongly dentated, yellowish-white line pass- 

 ing from each anterior tubercle to the two obtuse posterior tu- 

 bercles ; the lower part of each side is strongly tinged with dull 

 yellow, and the under part has a dark-brown hue mingled with 

 dull yellow, and a curved yellow band on each side : the sexual 

 organs are well developed, and of a dark-brown hue tinged with 

 red ; their anterior margin is semicircular, and below it there 

 are two glossy protuberances placed transversely ; the branchial 

 opercula are of a pale brown colour, and on each side of the 

 spinners there are three dark-brown triangular spots, which are 

 united at their bases. 



Three females of Epe'ira dorsuosa, two of which were adult 

 and the other immature, were comprised in the collection. This 

 species differs from the Epe'ira opuntia of Dufour (see Walcke- 

 naer's 'Hist. Nat. des Insect. Apt.' tom. ii. p, 140), to which it 

 is closely allied, in various particulars, and may readily be dis- 

 tinguished from it by the glossy convexities on the upper part 

 of its abdomen.
