Adult and immature males of this singular Drassus were 
captured in the Island of Teneriffe.

Clotho Paivant, n. sp.

inch; length of the cephalothorax <2 go, breadth 5; bre adth of

The ae hens is reniform, convex, glossy, with a large 
indentation in the medial line, and is of a dark-brown colour, 
the margins being rather the palest. The eyes are disposed 
on the anterior part of the cephalothorax, high above the frontal 
margin; three on each side describe a curve whose convexity 
is directed outwards, the posterior one being the smallest, and 
two, situated transversely between the curves, are much the 
largest of the eight. The falces are slender, subconical, and 
ver ‘tical ; the maxillz are ver y convex near the base, depressed, 
oval, and somewhat pointed at the extremity, and ’ereatly i in- 
clined towards the lip, which is triangular and pointed at the 
apex; the sternum is flat and reniform. ‘These parts are of a 
dark-brown hue, the extremity of the falces and the apex of 
the lip, which are the palest, having a tinge of red. The legs 
are strong, hairy, nearly equal in length, the third pair being 
slightly the shortest, and are somewhat paler than the cephalo- 
thorax; each tarsus is terminated by three claws; the two 
superior ones are curved and minutely pectinated, and the in- 
ferior one is inflected near its base. The palpi, which are 
robust and hairy, resemble the legs in colour; they mask the 
falces, and have a curved claw at their extremity. The abdo- 
men is oviform, glossy, sparingly clothed with short hairs, 
and projects over the base of the cephalothorax ; it is of a dull- 
brown colour, the under part being the palest, and has an ob- 
scure yellowish-white oval zone on the upper part, whose 
inner margin projects a point on each side into the intermediate 
brown space, near its middle; the superior spinners are tri- 
articulate, and have the spinning-tubes distributed on the in- 
ferior surface of their long terminal joint; they are directed 
upwards, and are curved towards the anus, which is oval and 
is encompassed by a dense fringe of long hairs, except at its 
posterior extremity: the sexual organs are nearly circular, 
and have a reddish-brown hue. 
The male is smaller than the female, and the colour of its 
cephalothorax, falces, maxilla, lip, sternum, legs, and palpi is 
ellowish-brown. ‘The abdomen is of a dark-brown hue
