118 DE. J. E. T. AITCHISON ON THE ZOOLOGY OF 



One specimen, taken between Hari-rud valley and Meshed. 



This Scorpion appears to have a very wide range. The localities hitherto known for 

 it are Sicily (Karsch), Nubia (Simon), Caucasus (L. Koch). And in addition to the 

 specimen now recorded from Afghanistan, the British Museum possesses others from 

 Egypt and Baghdad. 



The width of the tail of this species varies considerably with the size of the individual, 

 being narrower in small, wider in large specimens. 



Solpugidea. 



8. Galeodes araneoides (Pallas). 



Galcodes araneoides, Pallas, Spicil. Zool. ix. p. 37, pi. in. figg. 7, 8, 9 (1772) ; Simon, Ann. Soc. Ent. 

 Fr. (5), ix. p. 99 (1879). 



A single specimen (male) between Boznak and Shahad. 



According to Simon this species ranges from Persia and the Caucasus through Egypt 

 to Nubia and Algeria. 



[This Spider was caught at Boznak on the 5th June, 1885, in the branches of a bush. 

 Its size and the remarkahle appendages, shaped like small mushrooms, situated in a row 

 along the lower surface of its posterior pair of legs, drew attention to it. — J. E. T. A.]

 timate, which is smaller and placed slightly on the inner side. The posterior internal 

 series consists of two larger teeth in front, between which there may or may not be a 

 smaller accessory tooth and one behind. The posterior border of the digit is furnished 

 with one, two, or even three minute teeth. The inner surface of each chelicera is fur- 

 nished with hairs interspersed with spines. 



Maxillary palp testaceous, the tarsus and the proximal portion of the metatarsus only 

 being rufous. The whole limb bearing longer and shorter pale-coloured hairs ; the meta- 

 tarsus armed beneath with spines in addition to the hairs ; tarsus not armed with spines. 

 Eirst pair of feet testaceous, hairy ; metatarsus furnished with darker hairs ; tarsus 

 rufous. Tibiae of second and third feet armed above distally with a single spiniform 

 tooth ; metatarsi of the same feet armed above with a series consisting of five, sis, or
