the tergal plates of the abdomen are a shade darker than the 
lateral membrane. 
Ocular tubercle very slightly smaller than in S. ferox; 
structure of mandibles the same. Palpi and legs longer, the 
tibia of palp being distinctly longer than the width of the 
cephalic plate, which is only very slightly wider than the 
tibia or patella of the fourth leg. Spine-armature of legs as 
in ferov; the spine on the posterior side of the lower 
surface of the third tarsal segment of the second and third 
pairs of legs is very generally absent. 
Genital operculum with its posterior border a little more 
convex than in ferox; its two halves distinctly more thickly 
chitinized. 
3- Smaller than female, but with much longer legs (cf: 
measurements) ; the femur, tibia, and protarsus of the palp, 
the femora of the third and fourth legs, and the tibia of the 
fourth as well, lightly infuscate. Jalleoli long. 
Mandibles: teeth numerically the same as in the female, 
the two small ones on the upper jaw which lie between the 
second and third of the large ones are subequal, conical, and 
evenly spaced ; the flagellum has the bulbous portion high 
and black, the distal recurved portion is stout at the base but 
very short, its apex, which is truncate and pubescent, not 
projecting posteriorly beyond the point of origin of the basal 
plece. 
Measurement in millimetres.— 9 . ‘Total length 37; length 
of cephalic plate 7:2, width 10; width of tubercle 2; length 
of mandible 13, of palp 34, its tibia 11 ; protarsus and tarsus 
11°8; fourth leg about 53, its tibia and protarsus about 9°8. 
3. Total length 34; length of cephalic plate 7:5, width 
8:5, of tubercle 2; length of mandible 9°8, of palp 43:5, its 
tibia 14°5 ; protarsus and tarsus 14°2, of fourth leg 63, of its 
tibia 12°8, protarsus 13.

The female, of which the measurements are given above, is 
not by any means the largest in the Museum collection. One 
sent by Miss Woodward from Lake Nyasa has the trunk 
46 millim. long and the cephalic plate 11°5 millim. wide; the 
legs and palps are correspondingly longer, the proportion of 
the segments remaining the same. 
Of all the species that have been hitherto described, this 
new one appears to be most nearly related to S. merope of 
Simon, from Zanzibar. ‘The latter, however, seems to be 
smaller, seeing that the length given for several females is 
only 25 millim.; moreover, the cephalothorax and chelicere
