234 Mr. J. Blackwall on newly discovered species of Araneidea. 



each tarsus is terminated by three claws; the two superior ones 

 are curved, and the inferior one is inflected near its base. These 

 parts are of a brownish-yellow colour, the sternum, base of the 

 lip, and tibise of the first and second pairs of legs being the 

 brownest. The eyes are seated on black spots ; the four inter- 

 mediate ones form a trapezoid, the anterior pair, which consti- 

 tutes its shortest side, being the smallest of the eight ; those of 

 each lateral pair are placed obliquely on a small tubercle and are 

 almost in contact. The palpi have a brownish-yellow hue, the 

 digital joint being the brownest ; the cubital and radial joints 

 are short: the latter, which is the larger, is prominent at its 

 extremity, in front, and has several long bristles at its base ; the 

 digital joint is oval, with a long, conical, hornhke process at its 

 base, whose pointed termination extends to the extremity of the 

 cubital joint, and is provided with one or two long bristles ; it is 

 convex and hairy externally, concave within, comprising the 

 palpal organs, which are highly developed, prominent, compli- 

 cated in structure, with a small, black, curved, pointed spine at 

 the base, on the outer side, and are of a yellowish-brown colour. 

 The abdomen is oviform, convex above, and projects a little over 

 the base of the cephalo-thorax ; it is thinly clothed with hairs, 

 and of a dark, dull brown hue, that of the spinners being pale 

 yellowish-brown. 



This remarkable spider was discovered among moss growing 

 under trees in a wood on the northern slope of Gallt y Rhyg, in 

 the autumn of 1854.

The eyes are seated on black spots, the anterior pair of the 

 four intermediate ones forming the trapezoid, which are near to 

 each other, being the smallest and darkest of the eight. The 

 cephalo-thorax is oval, convex, glossy, with slight furrows on the 

 sides, which converge towards an indentation in the medial line : 

 the falces are powerful, conical, vertical, and armed with a few 

 teeth on the inner surface : the maxillae are enlarged at the 

 extremity, and inclined towards the lip, which is semicircular 

 and prominent at the apex : the sternum is broad, heart-shaped, 

 convex and glossy : the legs, which are moderately long, are pro- 

 vided with hairs and a few fine spines ; the fourth pair is slightly 

 longer than the first, which surpasses the second, and the third 

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

 the two superior ones are curved and pectinated, and the inferior 

 one is inflected near its base. These parts are of a pale yellow-
