260 Mr. R. I. Pocock on the Genera and 
3 .—Resembling female in colour, but with smaller head, 
much longer legs, &c.; the head-plate only a little more than 
half the length of the tibia of the palp and one third less 
than the length of the tibia or protarsus of the fourth leg. 
Protarsus of palp scopulate beneath ; palp longer than third 
leg, its tibia considerably longer than the tibia or protarsus 
of fourth leg. 
Mandible with dentition much resembling that of the 
female, though the teeth are smaller and the upper fang less 
strongly curved distally ; the flagellum with its basal part 
rising into a high crest with upright posterior border, rounded 
extremity, and convex anterior border; the distal portion 
short, curving upwards and backwards at a point on a level 
with the second tooth of the upper fang, and passing a little 
beyond the posterior border of the upstanding basal lamella, 
becoming gradually attenuated at the tip. 
Measurements in millimetres — 9. Total length (including 
mandibles) 56, length of mandible 15; width of head 11 ; 
length of palp 39, of first leg 32, of second leg 30, of third 
leg 38, of fourth leg 58; tibia of palp 12, protarsus and tarsus 
13 ; tibia and protarsus of fourth leg 11-5. 
3. Total length 54, length of mandible 11; width of head 
9°5; length of palp 50, of first leg 39, of second leg 36, of 
third leg 46, of fourth leg 67; tibia of palp 17, protarsus and 
tarsus 15°5; tibia and protarsus of fourth leg 13°5. 
Loc. Gadzima, on the Umfuli River (4200 feet alt.), in 
Mashonaland. An adult male and female sent by Mr. G. A. K. 
Marshall. 
I have great pleasure in dedicating this species to Mr. James 
ffolliott Darling, whose labours as a collector have added 
considerably to our knowledge of the natural history of 
Mashonaland. 
Solpuga sericea, sp.n. (Fig. 4.) 
Colour, when dry, of a greyish tint, owing to the clothing 
of white, yellow, or greyish-white hairs on the limbs and 
body, the limbs, especially the posterior pair, being furnished 
in addition with long silky white sete; in alcohol the head 
and mandibles are of an ochre-yellow, the mandible adorned 
with three black stripes, whilst on the head the tubercle is 
black and there is a black patch on each side, from whence a 
black curved line passes back to the middle point on the 
posterior margin of the head, this point being joined to the 
tubercle by a fainter median longitudinal line; the terga of 
the abdomen are black, but its sides are broadly white;
