96 ARANEIDEA. 
The abdomen is subpentagonal, broad, and well rounded on the sides behind; and with a strongish blunt sub- 
conical prominence at the middle of the posterior extremity ; from the base of the prominence to the 
spinners the hinder slope is abrupt and of rather considerable extent. The upperside and sides are whitish, 
with a broad blackish longitudinal central band above and an oblique blackish stripe near the middle of 
each side. The underside has a central black longitudinal stripe flanked on either side by a white one; 
the white stripes are spotted with dark grey. (Specimens in better condition than the only one as yet 
seen of this species would probably show a more distinct pattern on the abdomen than that above 
described.) The genital aperture is of moderate size and characteristic form.

Tmarus intentus, sp. n. 
Adult male, length 14 lines. 
The cephalothorax is of normal form ; the height of the clypeus is equal to half that of the facial space. The 
cephalothorax is of a yellow-brown colour, marked with deep red-brown and converging whitish lines 
thickening to stripes on the sides of the thorax ; three of these lines run backwards from the middle and 
outer sides of the ocular area, and from their point of convergence at the thoracic junction a broad well- 
defined white band runs to the extremity of the hinder slope, the rest of which is deep red-brown ; several 
minute scattered red-brown tubercles are visible on the upperside, but the spines with which they had 
once probably been surmounted have almost all been broken off. 
The eyes are normal in their general position and relative sizes. The four centrals form a quadrangle whose 
anterior side is much the shortest, the other three sides not differing much. . 
The legs are long, slender, 1, 2, 4, 3. They are of a brownish-yellow colour, spotted longitudinally on the fore 
sides of the femora of the first and seeond pairs with dark grey. The spiny armature has been somewhat 
injured, but there appears to have been three pairs of spines beneath each of the tibize and metatarsi of 
the first and second pairs of legs. 
The palpi are short, slender, and similar in colour to the legs. The radial and cubital joints are very short 
and furnished with bristles ; the former has its outer extremity slightly and obtusely produced. The 
digital joint is small but equal to the radial and cubital joints together in length; the palpal organs 
are simple, and have a tapering black spine curved round their extremity, and another on their inner 
side. 
The falces project forwards; they are moderate in length and strength, yellow-brown; the sides and extre- 
mities white. 
The mawille, labium, and sternum are yellow. 
The abdomen is oblong, very slightly produced in a somewhat segmented caudate form behind ; it is of a dull 
brownish hue suffused on the sides with whitish, and with a longitudinal whitish central band not well 
defined ; the upperside is covered thinly with minute red-brown tubercles, from each of which at one 
time no doubt there issued a long spine-like bristle, but these have almost all been broken off. The 
underside is of a dull brownish hue tinged with yellowish, and marked off from the sides by a longitudinal 
blackish stripe. 
The adult female differs from the male only in being a little larger and of a somewhat more generally yellow- 
brown hue. The legs are, however, shorter. The genital aperture is small and simple, but charac- 
teristic.

The cephalothoraw is of the ordinary form. The height of the clypeus is equal to half that of the facial space. 
The colour is dark yellow-brown, marked with converging yellowish lines, of which those indicating the 
caput (which run backwards a little way from each hind lateral eye), and another running from the
