12 REV. O, PICKARD-CAMBRIDGH ON EXOTIC SPIDERS. [Jan. 15, 
Gen. nov. Trrvs. 
Cephalothorax elongate-oval, rounded behind, broadly and a 
little roundly truncate before; lateral marginal impressions at the 
eaput gradual but distinct ; upper surface "strongly convex ; from 
the fore part of the caput to the hinder slope the rise is strong, a 
little curved and even, with a very slight dip at the thoracic 
junction. The sides of the cephalothorax project over the bases of 
the legs, making them appear to be articulated on the same plane 
as the sternum. ‘The thoracic indentation is very minute, and the 
other normal ones obsolete; hinder slope steep; height of the 
clypeus, which projects, is half that of the facial space, its fore 
margin overhanging the base of the falces. 
Eyes moderate and not greatly unequal in size; in two trans- 
verse curved rows; the hinder row considerably longest, its eyes 
are very nearly equally separated, and the convexity of its curve 1s 
directed forwards, while that of the anterior row is backwards. 
The hind-lateral eyes are larger than the hind-centrals and are 
placed outside a strong tubercle ; those of the anterior row on a 
well-marked transverse prominence or ridge. The fore-centrals 
are very nearly if not quite of equal size, the interval between 
them being about double that which separates each from the fore- 
lateral eye on its side. The central quadrangle is slightly broader 
than long, and its anterior side shortest. 
Legs short, rather slender, 4, 1, 2, 3; the femora strongly 
clavate or tumid at their posterior end, furnished with hairs and 
spies ; two pairs of these are beneath the metatarsi and three 
pairs beneath tibiz of the first pair. Tarsi end with 2 claws. 
Palpi (Q). The digital joint is double the length of the radial, 
rather claviform, and ending with a very minute, slightly curved 
single claw. 
Fulces moderate in length, powerful, subconical. 
Mawille rather short, strong, straight, but inclined to the 
labium ; rounded at their outer extremity, and a little impressed 
and obliquely truncate at their inner extremity. 
Labium short, broader than jong, narrowest at the apex, the 
onter corners of which are rounded, and the middle a little im- 
pressed. 
Sternum longer than broad, oval, slightly hollow-truncate in 
front, bluntish pointed behind, and its margins strongly indented 
by the basal joints of the legs. From the hinder end a chitinous 
plate runs between the coxe of the fourth pair of legs and 
spreading out behind them joins in with the upperside of the 
cephalothorax. 
Abdomen short, broad, its upper surface covered with a strong 
kind of agearnllosts coriaceous shield furnished with plumose and 
other hairs; sides, especially backwards, protuberant and tumid, 
these parts connected behind by transverse rug or folds, in the 
midst of which the spinners are placed and almost hidden in a 
circular cavity.
