SALTICID/E. 
at its anterior extremity, there is a short, longitudinal streak, composed of white hairs, which 
is not very conspicuous. 
An adult male of this minute Salticus is in the extensive collection of British Arcineidea 
belonging to Francis Walker, Esq., of Arno’s Grove, Southgate, Middlesex, in which locality 
it w'as taken in May, 1848. Mr. Walker has very liberally permitted descriptions to be made 
and published of any species comprised in his collection which were suspected to be unknown 
to arachnologists.

Length of the female, ^th of an inch ; length of the cephalo-thorax, rath, breadth, ^th; 
breadth of the abdomen, ^th; length of a posterior leg, T 3 5 ths; length of a leg of the second 
pair, jth. 
The legs are of a pale, reddish-brown hue, marked with brownish-black annuli; the fourth 
pair is the longest, then the third, and the second pair is the shortest; each tarsus is termi¬ 
nated by two long, curved, slightly pectinated claws. The palpi are short, and of a yellowish- 
white colour, with the exception of the axillary joint and the base of the humeral joint, which 
have a dark-brown hue. The cephalo-thorax is nearly quadrilateral; it slopes abruptly in the 
posterior region, and is prominent in front, projecting beyond the falces; its colour is very 
dark-brown, a longitudinal line of whitish hairs extending above each lateral margin; the 
upper part is covered with yellowish-brown and whitish hairs, a short line of the latter 
occurring in the middle, behind the posterior eyes. The falces are vertical, and armed with a 
few small teeth on the inner surface ; the maxillae are greatly enlarged at the extremity ; the 
lip is somewhat pointed, and the sternum is oval. These parts are of a very dark-brown 
colour, the extremities of the maxillae and lip being much the palest. The abdomen is ovi¬ 
form, projecting over the base of the cephalo-thorax ; it is of a brown colour, and is clothed 
with yellowish-brown, reddish-brown, and yellowish-white hairs intermixed; some whitish 
hairs occur in front, and a few of the same hue form a spot immediately above the spinners : 
in the middle of the anterior part there are two small, obscure, yellowish-white, concentric 
arcs of circles, to which succeeds a series of angular lines of the same colour, whose vertices 
are directed forwards ; the first two lines of the series are the most extensive, the extremities 
of the second being reflected and in contact with the first; the sides are of a brown colour 
blended with yellowish-white, and a broad, reddish-brown band extends along the middle of 
the under part; the superior spinners are of a dark-brown hue, and the other two pairs have 
a reddish-brown tint; the colour of the branchial opercula is pale-brown. 
The male greatly resembles the female, but it is rather smaller and darker coloured, and
