Dolomedes ornatus. PL II, fig. 19. 
Dolomedes ornatus, Blackw., Annals and Mag. of Nat. Hist., third series, vol. iii, p. 91. 
Length of the female, ^th of an inch; length of the cephalo-thorax, 5 ’ 5 th, breadth, Ath; 
breadth of the abdomen, ~th; length of a posterior leg, ±th; length of a leg of the third 
pair, |th. 
The eyes are seated on black spots on the sides and in front of the anterior part of the 
cephalo-thorax; the four anterior ones are minute, and form a straight, transverse row, the 
lateral ones, each of which is placed on a minute tubercle, being rather the smallest; the 
other four are large, and describe a trapezoid whose posterior side is much the longest; the 
posterior eyes of the trapezoid are seated on tubercles, and the anterior ones are the largest 
of the eight. The cephalo-thorax is convex, glossy, compressed before, rounded on the sides, 
and has a slight indentation in the medial line; a broad, brownish-red band, -which tapers to 
its posterior extremity, extends along the middle, and on each side of it there is a longitudinal 
brown band, which decreases in breadth to the lateral eye of the posterior row; the sides 
have a pale, dull-yellow hue, that of the lateral margins is black, and a blackish spot occurs 
on the frontal margin, below each lateral eye of the anterior row. The falces are conical, 
vertical, and armed with a few teeth on the inner surface; the maxillae are short, somewhat 
enlarged and rounded at the extremity, and slightly inclined towards the lip. These organs 
have a pale, dull yellowish hue ; a blackish streak extends along the former, and appears like a 
continuation of the spot on the frontal margin of the cephalo-thorax. The lip is nearly 
quadrate, and of a yellowish-brown colour, the sides being much the darkest. The sternum 
is heart-shaped, and of a pale, dull-yellow hue, with broad, brownish-black lateral margins. 
The legs are moderately long, provided with hairs and fine spines, and are of a pale-yellowish 
hue, with minute black spots; the fourth pair is rather the longest, the first and second pairs 
are equal in length, and the third pair is the shortest; 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 palpi resemble the legs in colour, and have a small, curved, pectinated claw at 
their extremity. The abdomen is oviform, thinly clothed with hairs, convex above, and 
projects over the base of the cephalo-thorax ; the upper part is of a yellowish-brown colour; 
at its anterior part there are four short, longitudinal streaks, the exterior ones of which increase 
in breadth to their posterior extremity; to these succeed three large spots placed trans¬ 
versely, the intermediate one being in advance of the other two; and between the latter and 
the spinners there is a series of short, transverse bars, somewhat enlarged at their extremities, 
which decrease in length to the coccyx; these streaks, spots, and bars have a brown hue; 
the sides and under part are of a pale-yellowish colour; the former are slightly tinged with 
brown, and a longitudinal, brownish-black band occurs on each side of the medial line of the 
latter ; these hands converge to the spinners, where they meet. 
The Rev. 0. P. Cambridge took two young females of this species, at Lyndhurst, in the 
New Forest, Hampshire, in September, 1858.
