brown, the femora and the base of the tibiae being the darkest; each tarsus is terminated by 
two curved, pectinated claws. The palpi are short, and resemble the legs in colour, but are 
somewhat paler. The abdomen is broadest in the middle, corrugated on the sides and at the 
posterior extremity, which is rounded, moderately convex above, and projects a little over the 
base of the cephalo-thorax; short, strong hairs, enlarged at their extremity, are dispersed 
over its superior surface, but are most abundant on the sides; its colour is yellow-brown, the 
sides and under part being much the palest; on the posterior half of the upper part there are 
dark-brown, slightly curved, transverse bars, which diminish in length as they approach the 
spinners, and in the medial line of the anterior part two rows of confluent, dark-brown spots 
form a very acute angle, whose vertex is directed backwards; the sides are marked with dark- 
brown streaks and spots, and from each pale-yellow branchial operculum a row of confluent, 
dark-brown spots passes obliquely to the spinners; the sexual organs have a broad, prominent 
piece, slightly notched at its extremity, connected with their anterior margin, and their 
colour is red-brown. 
The male bears a close resemblance to the female, but it is smaller, darker coloured, and 
its legs are slenderer. Its palpi are short, and the colour of the humeral, radial, and digital 
joints is brown, the humeral joint being the palest, and the cubital joint has a yellowish-brown 
hue ; the radial joint projects a long, curved, pointed, prominent apophysis from its extremity, 
on the outer side, and a strong, obtuse one, notched at its extremity, on the under side ; the 
digital joint is oval, convex and hairy externally, concave within, comprising the palpal organs, 
which are highly developed, not very complex in structure, and of a dark-brown colour, tinged 
with red. 
Specimens of this remarkable Thomisus have been taken in Portland on several occasions, 
by the Rev. O. P. Cambridge.
