4S8 Mr. J. Black wall on newly discovered Spiders 



first pair is much the longest, then the second, and the third 

 pair is the shortest ; each tarsus is terminated by claws of the 

 usual number and structure. The palpi are short, and of a dull 

 yellowish colour ; a long slender bristle projects from the ex- 

 tremity of the cubital joint in front ; the digital joint is oval, 

 convex and hairy externally, concave within, and with this con- 

 cavity the dark brown palpal organs are connected; they are 

 highly developed, prominent, not very complex in structure, 

 subglobose at the base, from which projects a long slender pro- 

 cess, directed obliquely downwards and outwards, whose pointed 

 extremity is curved. The convex sides of the digital joints are 

 directed towards each other. The cephalothorax is compressed 

 before, rounded on the sides, thinly clothed with hairs, convex, 

 glossy, with a shallow indentation in the medial line, and is of 

 a dark brown colour, with a large reddish-brown triangular 

 mark, whose vertex is directed backwards, in the cephalic region. 

 The eyes are seated on black spots on the anterior part of the 

 cephalothorax; the four intermediate ones form a square, the 

 two anterior ones, which are placed on a prominence, being the 

 largest of the eight; the eyes of each lateral pair are seated 

 obliquely on a small tubercle, and are near to each other, but 

 not in contact. The falces are long, conical, vertical, and of a 

 brownish-red colour. The maxillae are straight, and enlarged at 

 the extremity; and the lip has a short, oval form. These organs 

 have a dark brown hue, the apex of the latter being tinged with 

 dull yellow. The sternum is heart-shaped, and of a dull brownish- 

 yellow colour, with dark brown lateral margins. The abdomen 

 has an oblong-oviform figure ; it is somewhat depressed, sparingly 

 clothed with short hairs, glossy, and projects over the base of 

 the cephalothorax ; the upper part is of a yellowish- brown co- 

 lour, with a dark brown band in the middle, which tapers to the 

 spinners, and is somewhat irregular in outline ; the under part 

 has a dark brown hue, with an obscure pale yellow line extend- 

 ing from each branchial operculum to the spinners, and on each 

 side of those organs there are two minute spots of the same 

 colour.

The cephalothorax is compressed before, rounded on the sides, 

 convex, glossy, with a large indentation in the medial line; the 

 falces are conical, vertical, and armed with a few teeth on the 

 inner surface ; the maxillse are short, powerful, obliquely trun-
