86 Mr. R. I. Pocock on some 
are said to be a more or less obscure olivaceous brown, and 
the tibia of the palp lightly infuscate above. I can find no 
other satisfactory differentia] characters. The male of merope 
is undescribed. 
I have only seen two males of my species, one from Lake 
Nyasa and the other from Zomba. The former is dry, and 
I have consequently been compelled to take my measure- 
ments from the latter, which differs in having the femora and 
tibie of the legs more distinctly fuscous. The flagellum of 
the male of this species seems to resemble in its shortness that 
of S. niassa of Karsch, which is presumably from nearly the 
same locality. In S. néassa, however, the flagellum is rather 
longer, distally pointed, and dentate near the base. 
Solpuga Keyserlingii, sp. n. (Pl. IV. fig. 5.) 
Colour. Head, mandibles, palpi, and legs flavous; free 
thoracic segments and abdomen fusco-olivaceous. 
Head flattish, nearly as long as wide, tubercle large. 
Legs and palpi long, the latter normally robust, with its 
tibial segment as long as the tarsus and protarsus and nearly 
twice the width of the head; tibia of fourth leg a little shorter 
than that of the palpus. 
Mandibles with the internal ridges about twice as long as 
in S. paludicola. ‘The terminal fang long, curved, pointed, 
slender, with only one small tooth just in front of the third 
large fang. Flagellum with its basal part low and short, the 
recurved part rather short, not extending half across the 
distance between its point of origin and the base of the upper 
surface of the mandible ; slender throughout, but gradually 
pointed towards the apex, which is sinuate. 
Measurements in millimetres.—Length of trunk 28, of head 
6°5; width of head 7:5, of ocular tubercle 2; length of man- 
dible 10°5, of palp 438, its tibia 13°55; of protarsus and tarsus 
13°8 ; of fourth leg 62, its tibia 12°4, protarsus 11:9. 
Loe. ? A single male example belonging to the late 
Count Keyserling’s collection. 
Apart from the very obvious distinctions between this 
species and the preceding two which is supplied by the form 
of the flagellum, it may be recognized easily from the male of 
S. ferox by the greater length of its legs and palpi, relatively 
longer head, wider ocular tubercle, longer mandible, &c. In 
length of palpi and legs it more resembles S. paludicola ; but 
although the head is actually narrower in Keyserlingit, the 
ocular tubercle is the same size and the mandible distinctly 
longer, owing to the greater length of its terminal fang.
