greater relative strength of the coxal and femoral joints of the fore 
legs, it shows an evident affinity to Spiders of the genus Palpimanus 
(Duf.), although differing from them remarkably in the contour of the 
cephalothorax and some other characters. I have placed the genus 
Stenochilus provisionally, though doubtfully, in the family Drassides. 
Fam. AGELENIDES. 
Subfam. Lacnestna* (Cambr.) 
Nov. gen. Cyprpprx (nom. propr.). 
Characters of the Genus.—Cephalothorax oval, broader behind 
than before; caput full and bluff before, sloping forwards and round- 
ing off to the clypeus, which is of considerable height. 
Eyes eight, small, and not differing much in size, situate on the 
fore slope of caput in three transverse lines (2, 2, 4). Those con- 
stituting the first two rows form nearly a square, whose foremost 
side is rather wider than its hinder one; the third row consists of 
four eyes in a very slightly curved line (the curve directed forwards) 
greatly exceeding the other two lines in length; the figure thus 
formed by the eyes is somewhat of a T shape. 
Legs strong and moderately long, their relative length being 
4, 3, 1, 2; between 1 and 2 there is but little difference in length ; 
each tarsus ends with ¢hree curved claws, of which the upper ones 
are the largest, and have some strong pectinations underneath towards 
their base. 
Mazille short, strong, greatly enlarged at their base, curved, and 
inclined towards the /abiwm, which is broader at its apex than at the 
base, its upper half being nearly semicircular. 
Sternum short, broad, and somewhat heart-shaped. 
CypIPPE UNGUICULATA, nov. sp. (Plate XLIV. fig. 2.) 
Male adult, length 43 lines, length of cephalothorax 22 lines. 
The cephalothoraz is much narrower before than behind, but has 
no sudden lateral compression at the caput; its colour is a dark 
shining chestnut-brown ; and it is clothed with a very few fine hairs 
and bristles, chiefly on the caput; the normal furrows and indenta- 
tions are distinct though slight, that at the junction of the caput 
with the thoracic segments being the deepest ; the profile line shows 
a wider depression about the middle; otherwise the surface of the 
cephalothorax is smooth, even, and generally rounded off. 
The eyes form three transverse rows about equidistant from each 
other ; the two foremost of these rows are short, and consist each 
of two eyes; the hinder one is long and consists of four eyes; those 
of the foremost row are the largest, and the two centrals of the 
hinder row the smallest of the eight ; the eyes of the first two rows, 
together with the two hind central eyes, form two nearly straight 
* Subfam. Lachesina comprises the genera Lachesis (Savign.), Storena (Walck.), 
and Cydippe (Cambr.).
