256 Mr. R. I. Pocock on the Genera and 
since the species it contained were araneotdes of Pallas, fatalis, 
Licht., congeneric with it, and chelicornis congeneric with 
setigera. CU. Koch was the first to assign to the genus the 
significance it now bears, his action being tantamount to 
selecting chelicornis as the type. 
I have added the genus Zerta to the list of synonyms 
of Solpuga under the belief that it was based upon a 
young specimen of Solpuga. The type persephone from 
Algeria measures only 9 millim. long, and is said to differ 
from Solpuga in having a pair of ocular sete instead of a 
cluster of them and no spines on the fourth protarsus. But 
in an example in the British Museum from the same country 
and closely resembling the description of the type there are 
spines on the fourth protarsus. Moreover, in an immature 
specimen of what I believe to be Solpuga, sent with many 
other examples of the genus from the Umfuli River in 
Mashunaland by Mr. G. A. K. Marshall, the ocular tubercle 
has but two sete, a further resemblance between this specimen 
and the Algerian being noticeable in the presence of a distinct 
long third claw on the second, third, and fourth legs and the 
presence of only three malleoli on each side. Both these 
characters are, I am persuaded, signs of immaturity. Lastly, 
it may be added that the example from the Umfuli (measuring 
7 millim. in length) has the tarsus of the fourth leg with 
only five, instead of seven, differentiated segments, while 
those of the second and third have only two, or at most three, 
instead of four segments. In the British Museum example 
ot persephone the tarsal segments are as in Solpuga. 
The following species of the genus are represented in the 
British Museum. 
Solpuga dentatidens (Simon). 
Getulia dentatidens (Simon), Ann. Soc. Ent. Frauce, 1879, p. 116. 
Described from the White Nile. The Museum possesses 
two male examples from inland of Berbera in Somaliland 
(£. Lort Phillips). 
Solpuga brunnipes (Li. Dufour). 
Galeodes brunnipes, Dufour, Hist. Nat. Galeodes, p. 52, pl. ii. fig. 6 
(1861) ; Simon, op. et. p. 113. 
Of this species, which seems to range from Aigeria to 
Abyssinia, the Museum possesses a single female example 
obtained on the north-eastern shore of Lake Stephanie by 
Dr. Donaldson Smith.
