Length of the female, ^ths of an inch ; length of the cephalo-thorax, gth, breadth, ^th ;
breadth of the abdomen, gth ; length of a posterior leg, ,th; length of a leg of the second pair, &ths.
The legs are robust, provided with hairs and spines, and of a pale, reddish-brown colour,
with dark-brown annuli ; the fourth pair is the longest, then the third, and the second pair is
the shortest ; each tarsus is terminated by two curved, pectinated claws. The palpi are short,
and resemble the legs in colour. The cephalo-thorax is large, and nearly quadrilateral ; it
slopes abruptly in the posterior part, is prominent in front, and projects beyond the falces ; its
colour is very dark-brown, the region of the eyes being encompassed by a red-brown band,
clothed with red-brown and yellowish-white hairs intermixed, and the interval between the
eyes is supplied with long black and short red-brown hairs. The falces are strong, conical,
gibbous in front, near the base, vertical, and armed with a few teeth on their inner surface ;
these organs and the .maxillae are of a red-brown colour. The lip and sternum, which is oval,
have a dark-brown hue, the former being tipped with yellowish-brown and the latter thinly
clothed with whitish hairs. The abdomen is oviform, somewhat depressed, thickly covered
with hairs, and projects over the base of the cephalo-thorax ; the upper part is of an olive-
brown colour, with a few longitudinal, dark-brown streaks in the medial line, and some oblique
ones of a larger size on each side of it ; the whole is surrounded by an obscure, yellowish-
brown band, below which the sides have a dark-brown hue ; the under part is of a dull,
yellowish-brown colour, with a faint, longitudinal, brown band in the middle ; the branchial
opercula have a dull-yellow hue, and that of the sexual organs is dark, reddish-brown.
The male is smaller than the female, and the relative length of its legs is different, the
third and fourth pairs being equal in length, the first pair a little shorter, and the second pair
the shortest. The red-brown band encompassing the eyes is densely covered with yellowish-
white hairs, and its extremities, which are curved, extend to the posterior part of the cephalo-
thorax. The thighs of the first pair of legs have a black hue, and that of the tibiæ is dark-
brown, the genual joint having a reddish-brown tint. The thighs of the second, third,
and fourth pairs of legs are black, with a greater or less space of a pale, reddish-
brown colour at the base. The humeral joint of the palpi is of a dark-brown hue, the
other joints having a pale, reddish-brown tint ; the radial, which is rather larger than the
cubital joint, projects a long, obtuse, dark-brown apophysis from its extremity, on the outer
sid e ; the digital joint is oval, convex, and hairy externally, concave within, comprising the
palpal organs, which are highly developed, prominent at the upper part, not complex in structure,
and of a dark-brown colour. A broad, irregular, recPbrown band, crossed about one
third of its length above the spinners by a curved, yellowish-white line, extends along the
middle of the upper part of the abdomen j - it is bordered by a black band, and the whole is
surrounded by a yellowish-white one, below which the sides are black, and the under part is
of a dull, yellowish-brown colour. Sometimes the colour of the broad, irregular band extending
along the middle of the upper part of the abdomen is of a yellowish-brown hue, and the
curved, transverse, yellowish-white line is almost obliterated.
The sexes of Salticus coronatus, which is common in the woods of Denbighshire and Caernarvonshire,
differ so greatly in colour, that they have been described as distinct species.
They pair early in June.
Specimens of both sexes have been received from Mr. J. Hardy, who took them in
Scotland.

The attempt to identify the tcAraneus subflavus, oculis smaragdinis, item cui secundum clunes
très virgules crocees,” of Lister (‘De Aran.,’ tit. 33, p. 90), either with the Attus xanthogramma or
the Attus tripunctatus of M. Walckenaer, who has referred it to both (‘ Hist. Nat. des Insect.
Apt.,’ tom. i, pp. 415—418), is attended with difficulty in consequence of the brevity of the
descriptions and the want of specimens to compare with those species. It differs from both
in some particulars, but, on the whole, appears to resemble the former more than the latter.
The following is a summary description, from the Latin of Lister :
This spider is of a medium size, and for the most part of a yellowish colour. The cephalo-
thorax is large, nearly quadrate, very fiat, and broadest in front. In the relative size and
arrangement of its eyes it resembles its congeners, and their colour is emerald-green. The
abdomen is sub-cylindrical and pointed at the posterior extremity ; it has three conspicuous,
saffron-coloured streaks in the medial line of the Upper part, and is whitish underneath. The
male has the first pair of legs robust, hairy, and longer than the rest, the third pair being the
shortest. The digital joints of the palpi are tumid, and mask the falces, which are of a reddish-
black colour.
