lines of white hairs; the best-defined of the black markings are four large ones near the middle of the 
upperside, forming nearly a square between the single small posterior and the two anterior eminences, 
The underside is blackish, with a black rather raised spot edged posteriorly with white hairs on each 
side a little behind the genital process; this last is of moderate size, prominent, and has a small epigyne 
connected with it directed downwards and backwards. 
Hab. Mexico, Teapa in Tabasco (H. . A, Smith). 
AMAMRA, Cambridge, 
Amamra gibbifera, sp. n. 
Adult female, length 12 lines. 
Cephalothorax yellow-brown, dark brown in front and on the sides, and clothed with short hairs; elevation of 
the anterior portion of the caput strong, the sides of the occiput rather gibbous. 
Eyes in normal position. The four central eyes are on the front face of the elevation, forming a trapezoid 
broader behind than long; the upper pair are on strong tubercular prominences, wide apart, and much 
the largest of the eight. The lateral pairs are widely removed from the central four, and placed near 
the lower margin of the caput nearly in a straight transverse line with the two fore-central eyes. The 
height of the clypeus is half that of the facial space. ; 
The falces are strong, straight, subconical, a little directed backwards, and similar in colour to the cephalo- 
thorax. 
Legs short, strong, 1, 2, 4, 3, pale yellow in colour, the anterior portion of the femora dark blackish-brown ; 
they are furnished with hairs and a few inconspicuous spines, and the terminal claws spring from a small 
claw-joint. 
The mawille, labium, and sternum are yellow-brown. 
The abdomen is large and much elevated ; on each side of the anterior part above is a strong subconical 
rather divergent prominence, and behind them in the median line is a large roundish hump. ‘The colour 
of the abdomen is yellow-brown, mixed with darker and lighter patches and markings, but not apparently 
forming any very definite or describable pattern ; underside blackish. The spinners are short and compact, 
and the genital aperture is inconspicuous but characteristic in form.

_  Miagrammopes lineatus, sp. n. 
Female (¢mmature), length 14 lines. 
Cephalothorax of normal form, double as long as broad, broadest in front, where it is rounded. Colour dark 
brown, with two subparallel longitudinal pale yellow lines passing between the two middle eyes, and 
leaving a long dark brown stripe between them, broadest in the middle, and finishing off to a point at 
each end, and a broad marginal pale yellow band. 
Eyes in the ordinary position, two forming an oblique line on each side, seated on tubercles, the lower tubercle 
much the largest and round. The interval between the two middle eyes is considerably greater than that 
between the laterals. The eyes nearest the lateral margin of the caput are the largest. 
The legs are moderate in length, 1, 4, 2, 3, those of the third pair very short, the first pair strong and porrected, 
the fourth with a strong calamistrum on the metatarsi. The first three pairs are brown (the first darkest) 
above, yellow-brownish underneath ; the fourth pair pale yellow, the genuze and extremities of. the 
femora and tibie black ; tarsi and metatarsi darkish yellow-brown. 
Falces pale yellowish, with a black spot above near their base towards the outer side. 
Mazxille, labium, and sternum brownish-yellow. 
The abdomen is elongate-oblong, subcylindrical, dark brown above and on the sides, with two longitudinal 
parallel pale yellowish lines, leaving a central longitudinal dark brown band, There is also a longitudinal
