256 Mr. R. I. Pocock on the Genera and 



since tlie species it contained were araneoides oi Pallas, /atoZ/s, 

 Liclit., congeneric with it, and chelicomis congeneric with 

 setigera. C. Koch was the first to assign to the genus the 

 signiticance it now bears, his action being tantamount to 

 selecting chelicomis as the type. 



I have added the genus Zeria to the list of synonyms 

 of SoJ^^uga under the belief that it was based upon a 

 young specimen of Solpugn. The type persephone from 

 ^Algeria measures only 9 niiUira. long, and is said to differ 

 from b'olpnga in having a pair of ocular setee instead of a 

 cluster ot tliem 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 ot 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. JMarshall, the ocular tubercle 

 has but twosetffi, a further resemblance between this specimen 

 and the Algerian being noticeable in the presence of a distinct 

 long tliird claw on the second, third, and fourth legs and the 

 presence of only three malleoli on each side. Both these 

 characters are, 1 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 tlie second and third have only two, or at most three, 

 instead of four segments. In the British Museum example 

 oi persephone the tarsal segments are as in Solpuga. 



The following species of the genus are represented in the 

 British Museum. 



Solpuga dentatidens (Simon). 



Gcelulia dentatidens (Simon), Aiin. Soc. Ent. Frahce, 1879, p. 115. 



Described from the White Nile. The Museum possesses 

 two male examples from inland of Berbera in iSomaliland 

 {E. Lort Phillij)s). 



Solpuga h'unmpes (L. Dufour). 



Gakodes brunnipes, Dufour, Hist. Nat. Galeodes, p. 52, pi. ii. fig. 6 

 (1861) ; Simon, op. cit. p. 113. 



Of this species, which seems to range from Algeria to 

 Abyssinia, tiie Museum possesses a single female example 

 obtained on the north-eastern shore of Lake Stephanie by 

 Dr. Donaldson Smith.
