terior row ; these lines converge towards the posterior extremities 

 of two fine and nearly contiguous lines of the same hue origi- 

 nating immediately behind the intermediate eyes of the anterior 

 row, the four lines presenting the form of a small anchor ; on 

 each side of the medial line of the posterior part of the cephalo- 

 thorax there are several short, oblique, yellowish brown streaks, 

 and the lateral and frontal margins are yellowish white. Falces 

 short, subconical, vertical, and yellowish brown in front, except 

 at the base, which, with the outer side, is dark brown. Maxillse 

 gibbous at the base, inclined towards the lip, convergent at the 

 extremities, and of a pale yellowish brown colour. Lip oval, 

 dark brown, with a yellowish tinge at the apex. Sternum heart- 

 shaped ; it is of a yellowish brown colour, the lateral margins 

 and an obscure, narrow, longitudinal line in the middle being 

 dark brown. Legs long, moderately robust, provided with a few 

 sessile spines ; they are of a yellowish brown colour, with spots 

 and longitudinal streaks of dark brown ; the second pair is the 

 longest, then the first, and the fourth pair is the shortest ; each 

 tarsus is terminated by two curved claws, and has a climbing 

 apparatus on its under side. The palpi are short and resemble 

 the legs in colour. Eyes disposed on the anterior part of the 

 cephalo -thorax in two curved, transverse rows, forming a crescent 

 whose convexity is directed forwards ; the lateral eyes of each row 

 are seated on distinct prominences, and the intermediate eyes of 

 the anterior row, which are nearer to each other than those of 

 the posterior row, are rather the smallest of the eight. Abdomen 

 somewhat depressed, broader in the posterior than in the an- 

 terior region, but rather pointed at the spinners, projecting a 

 little over the base of the cephalo-thorax ; on the upper part and 

 sides it is of a dark olive-brown colour, spotted with numerous 

 irregular, yellowish white spots; those on the sides are the 

 largest, several small ones, forming a row immediately above the 

 spinners, being angulai', with their vertices directed forwards ; 

 the under part is yellowish white, three brown bands extend- 

 ing along the middle and uniting in a point at the base of the 

 inferior pair of spinners ; the sexual organs are of a deep reddish 

 brown colour.
