94 Mr. R. I. Pocock on some 
Genus GLUVIA. 
Gluvia nigrimanus, sp. n. (PI. IV. fig. 10.) 
&. Colour entirely pale yellow, except for the black ocular 
tubercle, the blackish fangs, and the dense black protarsus 
and tarsus of the palp, this segment, counting them as one, 
being only pale-coloured quite at its proximal and distal 
extremity. 
Carapace with its anterior border lightly concave in the 
middle, owing to the slight forward production of the mem- 
brane of the lateral portion in advance of the buttress which 
supports the mandible. 
Ocular tubercle hairy behind and in front, two of the 
anterior sete longer than the rest. 
Mandibles smooth above at the base, then strongly elevated 
before the base of the fang, armed above and externally with 
stout spiniform hairs and internally above at the base with a 
tuft of short hairs, and distally with a tuft of straight, long, 
thin hairs extending along the inner side of the upper fang 
as far as its apex; the upper fang rising abruptly from its 
base directed outwards and downwards, its upper edge nearly 
straight, only slightly depressed towards the apex, its inner 
edge entirely unarmed, carinate, and very lightly sinuate, the 
vertical area lying between the bases of the two fangs 
unarmed above, but furnished below with an external series 
of four teeth and an internal of three, the upper on each side 
being much larger than the rest, which gradually decrease in 
size ; lower jaw furnished with two teeth only in its proximal 
half, one very large, the other much smaller and situated 
posteriorly on the inner side of the large tooth ; the area in 
tront of the large tooth slightly elevated. 
Palpt longish and slender ; femur and tibia spinous inter- 
nally ; protarsus and tarsus distinctly arcuate, closely hairy, 
but not spined. 
Legs long and slender, 
Measurements in millimetres.—Total length of trunk 24 ; 
width of head 7, length 5; width of tubercle 1; length of 
mandible 9, of palp 26°5, its tibia 9°2, protarsus and tarsus 
8:5; of fourth leg 54. 
Loe. ? (probably Meshed, Afghanistan ; obtained by 
the Afghan Delimitation Commission). 
In colouring and structure of its mandibles this species 
approaches G. magna (Hancock), from Texas; but the 
latter has the upper jaw of the mandible cylindrical, and not 
carinate below; the lower jaw is strongly curved distally,
