and those of the anterior row, which is situated immediately above the frontal margin, are 
the smallest and darkest of the eight. The falces are subconical and vertical; and the 
maxillae, which are convex at the base, have an oblique, transverse furrow near their 
extremity, and are curved towards the lip. These organs are of a yellowish-brown colour, 
the falces having a tinge of red. The lip is longer than broad, and rounded at the apex; 
and the sternum is oval and glossy. These parts have a dark-brown hue, the lip being 
rather the paler. The legs are robust, and provided with hairs and sessile spines ; the fourth 
pair is the longest, then the first, the third pair being the shortest, and each tarsus is 
terminated by two curved, pectinated claws; the colour of the coxa? and femora is yellow, 
the extremity of the latter, with the genual joint and tibia of the first and second pairs, 
having a brown-black, and those of the third and fourth pairs a dark-brown hue, and the 
colour of the metatarsi and tarsi of all the legs is red-brown. The palpi are short, and of a 
yellow-brown colour, with the exception of the radial and digital joints, which have a brown 
hue. The abdomen is oviform, somewhat depressed, and projects a little over the base of the 
cephalo-thorax; it is thickly covered with hairs, those at its anterior extremity being the 
longest, and is of a dull-black hue; the colour of the branchial opercula is deep-yellow, 
and that of the sexual organs reddish-brown. 
According to M. Koch, the male has the cephalo-thorax, falces, sternum, and the genual 
and tibial joints of the first and second pairs of legs of a black hue. The cubital and radial 
joints of its palpi, which have a brownish-rust colour, are short, and the latter, which is the 
stronger, has a tooth-like prolongation on its side; the palpal organs have a black hue, 
and are provided with a small, brownish hook. 
The Rev. O. P. Cambridge took an adult female of this small Drassus among the 
sand-hills at Southport, in June, 1859.

The eyes, which are nearly equal in size and pellucid, are disposed on the anterior part 
of the cephalo-thorax in two curved, concentric, transverse rows, whose convexity is directed 
backwards; the four intermediate eyes form a square, the two posterior ones, which are oval 
and very near to each other, being rather the largest of the eight, and each lateral eye of the 
posterior row is seated on a small tubercle. The cephalo-thorax is oval, convex, glossy, 
thinly clothed with hairs, and marked on the sides with slight furrows converging towards a 
narrow indentation in the medial line; it is of a pale, yellowish-brown colour, veined with
