94 Mr. J. Blackwall on new species of Araneidea. 



tei'mediate eyes of both rows describe a trapezoid whose anterior 

 side is the shortest ; and the eyes of each lateral pair, which are 

 rather the largest of the eight, are seated obliquely on a tubercle. 

 The cephalothorax is large, convex, glossy, compressed before, 

 and rounded on the sides, which are marked with furrows con- 

 verging towards an elongated indentation in the medial line ; it 

 is depressed and broadly truncated in front, and of a red-brown 

 colour, the cephalic region, which is much the darkest, having a 

 brownish-black hue. The falces are very powerful, conical, ver- 

 tical, convex in front near the base ; armed with teeth on the 

 inner surface, and of a brownish-black hue. The maxillse are 

 strong, enlarged and rounded at the extremity, and somewhat 

 curved towards the lip : the lip is longer than broad, dilated 

 about the middle, and truncated at the apex; and the sternum 

 is oval and glossy. These parts have a red-brown hue, the 

 sternum being much the palest, particularly in the middle. 

 The legs are robust, provided with hairs and sessile spines, and 

 of a red-brown colour ; the metatarsi of the posterior pair are 

 provided with calaraistra on their superior surface, and each 

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

 curved and pectinated, and the inferior one is inflected near its 

 base ; the first pair the longest, then the fourth, and the third 

 pair the shortest. The palpi resemble the legs in colour, the 

 radial and digital joints being the darkest, and have a curved, 

 pectinated claw at their extremity. The abdomen is oviform, 

 convex above, and projects over the base of the cephalothorax ; 

 it is thinly clothed with hairs, and of a brown colour obscurely 

 freckled with yellowish white, the under part being the palest ; 

 a yellowish-white band extends along the middle of the upper 

 part, about two-thirds of its length,, and an obscure longitudinal 

 line of the same hue occurs on each side of the middle of the 

 under part ; the sexual organs are highly developed, and of a 

 dark reddish-brown colour ; the spinners are eight in number, 

 and, with the exception of those of the inferior pair, which are 

 united throughout their entire length and have a yellowish- 

 white hue, are of a red-brown colour. 



This spider was captui'ed in the Isle of Wight, on the 1st of 

 August 1858, by Frederick Bond, Esq., who gave it to the Rev. 

 0. P. Cambridge; it was forwarded to me for inspection by 

 Mr. R. H. Meade.
