36 Mr. J. Blackwall on newly discovered Spiders 



side; the digital joint is oval, with an obtuse, glossy, black 

 process at its base curved outwards ; it is convex and hairy ex- 

 ternally, concave within, comprising the palpal organs, which 

 are highly developed, prominent, complicated in structure, with 

 several obtuse and acute processes at their extremity, the most 

 conspicuous of which is crescent-shaped, and are of a dark red- 

 dish-brown colour intermixed with yellowish-brown. The convex 

 sides of the digital joints are directed towards each other. 



I have much pleasure in connecting the name of that enter- 

 prising traveller and zealous naturalist, John Gray, Esq., of 

 Bolton, with this elegant Epe'ira, which is remarkable for having 

 the fourth pair of legs longer than the second pair. 



Epe'ira astuta.

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 

 rather the largest and darkest of the eight; the eyes of each 

 lateral pair are seated obliquely on a tubercle, and are near to 

 each other, but not in contact. The cephalothorax is compressed 

 before, rounded on the sides, sparingly clothed with whitish 

 hairs, convex, glossy, and has an indentation in the medial line ; 

 the falces are powerful, conical, convex in front, vertical, and 

 armed with a few teeth on the inner surface. These parts have 

 a brownish-red colour, a brown band extending along the middle, 

 and another, of the same hue, above each lateral margin of the 

 former. The maxillae are short, straight, and enlarged and 

 rounded at the extremity; and the lip is semicircular, but some- 

 what pointed at the apex. These organs are of a dark brown 

 colour, their extremities having a yellowish-white hue. The 

 sternum is heart-shaped, with small eminences on the sides, 

 opposite to the legs, and has a reddish-brown hue, with a tinge 

 of yellow in the medial line. The legs are long, provided with 

 hairs and spines, and have a brownish-yellow hue, the extremity 

 of the joints being tinged with brown ; the first pair is the longest, 

 then the fourth, and the third pair is the shortest ; the tarsi are 

 terminated by claws of the usual number and structure. The palpi 

 resemble the legs in colour, and have a curved pectinated claw at 

 their extremity. The abdomen is oviform, moderately hairy, convex 

 above, and projects over the base of the cephalothorax and slightly 

 beyond the spinners ; the upper part is of a yellowish-brown co- 

 lour; a yellowish-white medial band, whose sinuous margins 

 are finely bordered with black, tapers from the anterior to the
