Solifugee in the British Museum. 87 
Of the previously described species, which are unknown to 
me, it perhaps approaches the Algerian S. aciculata in the 
structure of its mandibles. The latter, however, has the 
basal portion of the flagellum very high, the terminal portion 
more elevated in consequence, and the terminal fang of the 
upper jaw short. It may also be allied to S. Schweinfurthi 
of Karsch. 
Solpuga Monteiri, sp.n. (Pl. IV. fig. 6.) 
?. Colour entirely pale except for indications of blackness 
upon the cephalic plate. 
Allied to female of ferox, but with legs and palpi rela- 
tively shorter and stouter ; cephalic plate equalling in width 
the length of the tibia of the palp, tibia of palp equalling the 
protarsus and tarsus taken together; the latter clothed below 
with soft hairs and not presenting those short, erect, truncate 
hairs which are observable in 9. ferox. 
3g. Head and mandibles infuscate above; head about as 
wide as long, its anterior border produced forwards, tubercle 
large. Mandibles with the internal ridges longish, as in 
S. Keyserlingiti ; terminal fang of the upper jaw rather short, 
slightly curved at the apex, the two anterior teeth well 
developed and sharp, followed by two minute and separated 
denticles ; flagellum with its basal portion low, mostly pale ; 
distal portion, which begins to take its backward curve on a 
level with the second tooth of the upper jaw, very long and 
slender, projecting backwards past the ocular tubercle, slightly 
sinuate in its distal third. Palpe longish and robust (cf. 
measurements). 
Measurements in millimetres. — Adult ?. Total length 
(abdomen small) 33; width of head 12, length 9; width of 
tubercle 2°5; length of mandible 16:5, of palp 38, its tibia 12, 
protarsus and tarsus 12°2; length of fourth leg 56, of tibia 
10:5, of protarsus 10. 
3. Total length 30, of head 7, width of head 7, width of 
tubercle 2; length of mandible 10; palp 36, its tibia 11:5, 
protarsus and tarsus 11°3; of fourth leg 52°5, its tibia 10. 
Loc. Delagoa Bay (Mrs. Monteiro). 
A third specimen, a female measuring, with distended 
abdomen, 33 millim., but with the head about 7:8 millim. 
wide, has the palpi relatively longer, the tibia being 8°5, and 
therefore noticeably longer than the width of the head; the 
latter, too, is distinctly fuscous above; moreover, the free 
thoracic segments and the abdominal dorsal plates are lightly 
infuscate,
