soot-coloured lines, and has narrow, black, lateral margins. The falces are powerful, conical, 
and rather prominent; the maxillae are convex at the base, obliquely depressed in the middle, 
enlarged at the extremity, and curved towards the lip, which is oval; and the sternum 
is broad, glossy, and heart-shaped, with small eminences on the sides, opposite to the legs. 
These parts are of a brown colour, the lip and margins of the sternum being the darkest, and 
the maxillae, which are slightly tinged with yellow, being much the palest. The legs are 
robust, provided with hairs, sessile spines, and hair-like papillae on the inferior surface of the 
tarsi, and have a pale, yellow-brown hue; the fourth pair is the longest, then the first, and 
the third pair is the shortest; each tarsus is terminated by two curved, pectinated claws. 
The palpi resemble the legs in colour, with the exception of the radial and digital joints, 
which have a brown hue; the humeral joint is curved towards the cephalo-thorax; the radial 
joint projects from its extremity, towards the outer side, a strong apophysis, whose enlarged 
and depressed termination applies to the superior surface of the digital joint. This last joint 
is oval, convex and hairy externally, concave within, comprising the palpal organs, which are 
highly developed, moderately complex in structure, with a depressed, slightly curved process 
towards the inner side, which is directed downwards, and are of a red-brown colour. The 
abdomen is oviform, convex above, and projects a little over the base of the cephalo-thorax; 
it is of a brownish-black colour, but is clothed with glossy, reddish hairs, and has some long, 
black hairs at its anterior extremity; on each side of the medial line of the anterior region of 
the upper part there are three minute, pale spots, disposed in pairs; to these spots succeeds 
a series of curved, transverse lines of the same hue, which have their convexity directed 
forwards, and diminish in extent as they approach the spinners; a faint, longitudinal, whitish 
line occurs on each side of the middle of the under part, and the branchial opercula and 
spinners have a pale, yellow-brown hue. The light-coloured spots and lines are little 
conspicuous except when the spider is submerged^ in spirit, and then the colour and lustre of 
the reddish hairs disappear. 
An adult female of this species has not yet been discovered; individuals which, judging 
from their dimensions, must nearly have arrived at maturity, differ from the male in colour 
solely in being paler. 
Specimens of Drassus clavator were received from the Rev. 0. P. Cambridge, who took 
an adult male on the sand-hills at Southport, in the spring of 1859, and immature females 
under stones in Portland, in the autumn of the same year.
