It is remarked in the description (0. c.) of this spider that the falces have along their 
outer surface a series of impressed punctures or minute pock-marks, forming part of a 
stridulating-apparatus ; but more recent examination under microscopic power shows 
this to have been incorrect: what appeared to be impressed markings are numerous 
minute granulations, which, under certain conditions of light and position, seemed to 
be impressed instead of elevated. Probably these granulations, which have among 
them a few larger denticule, have (in connection with those on the inner side of the 
humeral joints of the palpi) a stridulating function. 
CAREPALXIS, L. Koch; Cambridge. 
Carepalxis rotunda, sp. n. 
Adult female, length 21 lines. 
Cephalothoraw short; caput of large size, the occipital portion considerably and obtusely elevated, with a sub- 
conical eminence at each corner of the ridge-like top of the elevation. The height of the clypeus is rather 
less than half that of the facial space, or about two diameters of the fore-central eyes. The colour of the 
thorax is brownish-yellow, that of the caput dark reddish-brown, the top ridge and subconical eminences 
dull yellowish. The caput is clothed with short, coarse, whitish hairs. 
Eyes normal; the four centrals form a quadrangle broader than long, and its anterior side considerably shorter 
than the posterior. Each of these four eyes is seated on a roundish tubercular prominence, the posterior 
prominences considerably the largest and bearing the larger of the eyes; those of each lateral pair are a 
long way removed from the central group, they are seated on small tubercular eminences, contiguous 
to each other and near the fore corners of the clypeus. 
Legs short, 1, 2, 4, 3, moderately strong, pale yellowish, the fore part of the femora and the genus dull olive- 
yellowish-brown, the other joints indistinctly annulated with dusky yellow-brown; they are furnished 
chiefly with hairs, the spines few and weak. 
Palpi yellowish, indistinctly annulated with dusky yellow-brown. 
Falces strong, straight, subconical. Colour yellow-brown. 
Mazille and labium normal, of a dusky brownish colour. 
Sternum small, heart-shaped; its posterior extremity between the coxe of the fourth pair of legs, which are 
here nearly touching each other. Colour dull yellowish, somewhat suffused with whitish. 
Abdomen large, circular, projecting greatly over the thorax, looked at in profile almost hemispherical; towards 
the fore extremity near the margin on each side is a small subconical eminence, behind which are two 
others of a smaller size in a longitudinal line, scarcely visible above the general level. It is of a dull 
pale brownish hue, thickly covered with whitish, but presenting a fairly well-defined pattern. At the 
middle of the fore extremity are three short, white, parallel, longitudinal lines or stripes, the central one 
trifid at its posterior extremity ; on the hinder part is a tapering, angulated, dark brown marking, and 
on each side is a well-defined longitudinal black wavy or subangulated line running from the fore end to 
the spinners ; a broad, longitudinal, dark brown band occupies the middle of the underside, four white spots 
surround the spinners, and two others of larger size are in a transverse line in front of them. The genital 
aperture is small and inconspicuous.
