^vliere tlie two are united by a transverse bar of the same hue ; 

 two pale brown spots occur behind the posterior pair of eyes, 

 and the whole is clothed with white liairs having a silvery lustre. 

 The fakes are powerful^ conical, vertical, armed with teeth on 

 the inner surface, and of a pale dull-yellow colour, with an ob- 

 scure brown line extending along their inner side, and passing 

 obliquely above their extremity. The maxillse are short, strong, 

 and greatly enlarged and rounded at the extremity ; the lip is 

 semicircular, but somewhat pointed at the apex -, and the ster- 

 num, which is heart-shaped and hairy, has eminences on the 

 sides, opposite to the legs. These parts are of a dark-brown 

 colour; the extremity of the maxillse and the apex of the lip 

 have a brownish-yellow hue ; and a band extending along the 

 middle of the sternum, from each side of which a streak is directed 

 obliquely backwards and outwards, is of a pale dull-yellow co- 

 lour. The legs are long, slender, provided with hairs and a few 

 spines, and are of a dark-brown hue, with broad brownish-yellow 

 annuli ; 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 structure. The palpi are long, of a pale 

 dull-yellow colour, and have a curved, pectinated claw at their 

 extremity. 



Although this spider differs remarkably in form and in some 

 other particulars from Argyopes caudatus (see the 'Annals and 

 Mag. of Nat. Hist.^ ser. 3. vol. xvi. p. 346), yet it possibly may 

 be an immature individual of that species, to which it bears 

 some striking points of resemblance.

The eyes are disposed on the anterior part of the cephalo- 

 thorax in two transverse rows; the four intermediate ones are 

 seated on a protuberance, and form a trapezoid, the two anterior 

 ones, which are nearer to each other than the posterior ones, 

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

 placed apart on a strong tubercle, and are distant from the four 

 intermediate ones. The cephalothorax is large, compressed be- 

 fore, truncated in front, and rounded on the sides, which are 

 marked with furrows converging towards the middle ; the 

 cephalic region, which is greatly elevated above the posterior 

 part, has four conical glossy tubercles disposed in a transverse
