270 - ARANEIDBA. 
the tibie and metatarsi annulated with, not all well-defined, black-brown annuli; rather less’ than 
one-half of the femora of the third and fourth pairs is black-brown. 
Palpi short, yellow ; digital joint and palpal bulb dark brown and of large size. Palpel organs highly developed 
and prominent. 
Sternum black-brown, marked with several converging brownish-yellow marks, and three white spots, one at 
each of the anterior corners, and the third (forming a triangle with the others) at the posterior extremity. 
Abdomen of a pale dull luteous hue, marked pretty closely with black, most thickly on each side of the fore 
part and above the tuberculiform prolongation, where it forms a largish transverse oblong patch, including 
several whitish spots in the middle and a short longitudinal central black bar in front; on either side of 
this bar is an oblique diffused white patch. The extremity of the hinder prominence bears a white spot ; 
there are also two very distinct white spots in a transverse line halfway between the oblique white 
patches and the anterior margin, at the middle of which is a small white spot. The underside is black, 
and on the middle of the lateral margins on each side is a small indistinct white point.

AMAMRA, Cambridge. 
Amamra clivosa, sp. n. 
Adult female, length 34 lines. 
This spider is closely allied to A. bituberosa, Camb. (antead, p. 55, t. 3. figg. 11, 11 a—e), but may be at once 
distinguished by the broader cephalothorax and more robust caput, a slight difference in the form of the 
genital aperture, the larger size of the abdominal eminences, as well as in colours and markings. 
The cephalothorax has a deep reddish-brown transverse band at the occiput; the rest of the caput and thorax 
are reddish-yellow-brown, with four rather converging, fine, darker brown lines running from the central 
ocular rectangle to the occiput, and a transverse line of the same colour on each side of the caput, and in 
fact traceable quite over and meeting on the middle of the caput, and the thorax is also marked with 
brown. The ocular area and clypeus are deep reddish-brown; the whole is clothed thinly with short 
- greyish hairs. 
The eyes do not appear to differ much from those of A. bituberosa. 
Falces pale yellow-brown, with the extremities red-brown. 
Legs short, strong, subequal in length, 2, 4, 1, 3, the femora of 1, 2, 4 deep brown, while those of 3 are yellow- 
brown, banded with paler brownish-yellow ; the rest of the legs is dull yellowish, indistinctly annulated 
and marked with darker yellow-brown. They are furnished with not very long nor strong spines and 
coarse grey hairs. 
Mazille and labiwm dark yellow-brown, with pale whitish extremities. 
Sternum dark yellow-brown. . 
Abdomen large, oval; near the fore extremity on the upperside are two strong , somewhat roundly obtuse, 
humps or eminences in a transverse line, with a slight subconical point at the top (rather behind) of 
each. In front of these eminences, nearer to the fore margin in the centre, is a very much smaller 
protuberance, forming a yellowish patch, with a small group of short black bristly hairs in front of it. 
The abdomen is yellow-brown in colour, clothed with short hairs and, thinly, with short black spine-like 
bristles, some of which appear to be‘of a slender lanceolate form. On the hinder part between the 
prominences and the spinuers, and near the former, are two strongish, depressed, dark brown spots in a 
transverse line, with a smaller dark brown spot edged with yellowish behind each; this is followed 
halfway to the spinners by two more, larger, depressed, curved spots of the same cole, and immediately 
behind each of these is a largish, well-defined, somewhat inverted umbrella-shaped, deep black-brown 
- patch, edged with yellowish, and followed to the spinners by two rather converging lines of small 
deep-brown points or spots, five spots in each line. The spinners are short. and compact. The underside 
is for the most part dark brown. ‘The genital aperture and process are of characteristic form, though 
much like those of A. bituberosa.
