Buthus eminit, POCOCK. 
Ann. Mag. Nat. Hist. (6), vi. p. 98, 1890. 
Locality, near Aimola in the Boran country, 3,000 ft. and several 
specimens without locality. 
Buthus polystictus, POCOCK. 
Ann. Mag. Nat. Hist. (6), xviii. 1896, p. 178, Pl. XI. fig. 1. 
Locality, Turfa, in Somaliland; Shebeli River, and west of 
Shebeli River, previously recorded from the Goolis Mountains, 
inland of Berbera. 
Parabuthus heterurus, sp. n. 
Closely allied to the species inhabiting the countries bordering 
the Red Sea, e. g., /zosoma, huntert, and granimanus, but differing 
from these three in having the 5th segment of the tail yellow and 
not infuscate, while the 4th segment and the vesicle are normally 
deeply infuscate. A tendency towards the paleness of the seg- 
ment is very visible in some specimens of granzmanus, but from the 
latter heterurus may be recognized by having the hands smooth, 
punctured, and not granular. In having the hands smooth and 
punctured, the species lies close to “osoma and huntert; but, apart 
from the coloring of the 5th caudal segment, it may be recognized 
from the former by its longer, narrower tail. In the latter respect 
it approaches Auntert, but the tail segments are broader and the 
digits are not basally toothed. 
The typical examples present the following measurements : — 
2 Total length about 90 mm.; length of carapace, 9.5 mm. ; 
of tail, 50 mm. ; width of Ist and 4th segments, 6.5 mm.; length of 
Ist, 6.3) mim, of 4th, 3.5) mm. 
d Total length, 85 mm.; length of carapace, 8.8 mm.; of 
tail, 52 mm.; width of Ist and 4th segments, 6.5 mm.; length of 
Ist, 6.5 mm.; “of 4th, Om: 
Locality, Hargesa, 5,000 ft. and Silul, in Somaliland; Shebeli 
River, TYPES; and from pools of water to the west of Shebeli 
River, 15.12.94. 
Parabuthus sp. 
A single male example from the Shebeli River (24.8.94) resem- 
bles the preceding, but has the 5th caudal segment infuscate, and 
both it and the 4th very weakly keeled below. Without further 
specimens it is difficult to form an estimate of the value of these 
characteristics.
