Mr. J. Blackwall on newly discovered species of Araneidea. 175 



loug the upper part of the femora, genua, and tibiae; the an- 

 terior and posterior pairs, which are the longest, are equal in 

 length, and the third pair is the shortest ; each tarsus is termi- 

 nated by two curved claws, below which thei-e is a scopula. The 

 palpi have a yellowish brown hue, the digital joint being the 

 darkest. The cephalo-thorax is nearly quadrilateral, prominent 

 in front, projecting beyond the base of the falces ; it is covered 

 with yellow ish brown and black hairs intermixed, and has some 

 long yellowish ones below the anterior row^ of eyes ; a narrow 

 black line occurs on the margins, immediately above which there 

 is a longitudinal one of a yellowish brown hue. The falces are 

 short, powerful, conical, and vertical ; the maxillae are straight, 

 and enlarged and rounded at the extremity ; and the lip is some- 

 what oval. These parts have a yellowish brown tint, with the 

 exception of the bases of the maxillee and lip, which have a dark 

 brown hue. The sternum is small, oval, and of a brown colour, 

 the margins being much the darkest. The abdomen is oviform, 

 pointed at the spinners, convex above, projecting over the base 

 of the cephalo-thorax j it is densely clothed with short yellowish 

 brown hairs, interspersed with long black ones; a faint red- 

 brown line passes from the spinners along the middle of the 

 upper part, more than half of its length, and then separates into 

 two diverging branches which extend to its anterior extremity and 

 form a very acute angle; these red-brown lines have an obscure, 

 narrow, whitish border, bounded by a faint red-brown parallel 

 line, and an obscure whitish line bisects the angular space com- 

 prised between the diverging branches of the medial line ; on 

 the under part there is an obscure dark band, which tapers gra- 

 dually from the sexual organs to the spinners ; and the branchial 

 opercula have a pale yellow hue. 



It affords me much gratification to connect with this species 

 of Salticus the name of so accomplished a naturalist as the 

 Rev. Leonard Jenyns, M.A., F.L.S. &c., to whose liberality I am 

 indebted for this opportunity of describing the adult female. It 

 was comprised in a collection of spiders made in Cambridge- 

 shire, and obligingly placed at my disposal by Mr. Jenyns in 

 February 1853.
