XXV.—On the Genera and Species of Tropical African 
_ Arachnida of the Order Solifugee, with Notes upon the 
Taxonomy and Habits of the Group. By R. I. Pocock, 
of the British Museum of Natural History. 
THE Ethiopian Region, or that part of Africa which lies to 
the south of the Sahara, is singularly poor in genera of 
Solifuge. Two at most, namely Hexisopus and Ceroma, are 
peculiar. The others are common to the Mediterranean district 
of the Palearctic, but of these only Solpuga can claim to 
be regarded as typically Ethiopian, since the rest are to be 
looked upon as emigrants southwards from the desert tracts of 
Egypt and Nubia to physically similar areas in the countries 
of the Somali and Masai. This dearth of genera, however, is 
largely counterbalanced by richness in the number of species 
of the genus Solpuga, which spreads from Somaliland and the 
Congo over the whole of South Africa, including Cape Colony. 
It is with some of the species of this genus that have recently 
come to hand that this paper largely deals. The notes con- 
cerning habits have been principally collected from the material 
on this subject kindly supplied by Mr. G. A. K. Marshall. 
The African genera may be classified according to the 
following table. Most of the genera not represented in the 
Ethiopian Region will, I suspect, fall into the Solpugine of 
the family Solpugide, though, perhaps, a few subfamilies in 
addition to the two here recognized will have to be ultimately 
established.
