GUDE : LIST OF HELICOID LAND SHELLS. IO3 



vi. ARABIA. 



Like many of the preceeding regions, Arabia has but a scanty 

 molluscan Fauna. The bulk of the HeUcoids show an intimate 

 affinity with the Fauna of Asia minor. One species of Lejmnia found 

 in the south, however, connects this region with Abyssinia.

vii. PERSIA. 



The principal contribution to our knowledge of the Persian Helicoids 

 is by Prof von Martens, who published the malacological results of 

 Prof. Hausknecht's travels in Persia as well as Kurdistan, Mesopo- 

 tamia and Syria. The entire molluscan fauna is essentially palaearctic, 

 no Eastern Asiatic forms having been found. Dr. Westerlund 

 described the material collected in North Persia by Keyserling and 

 Bienert, and Mousson those collected by Dr. Sievers ; Dr. Pohlig 

 published the results of his own travels in North Persia ; Prof. 

 Boettger enumerated the shells procured by Dr. Radde's expedition 

 to Transcaspia and Chorassan, and also those collected by Hans Leder 

 and Otto Herz, while Issel catalogued the shells acquired during the 

 Italian mission to Persia. The most recent additions are by Mr. 

 E. a. Smith from the Urmi district, and Pfarrer Naegele who made 

 considerable collections, the shells being described by himself and by 

 Dr. Kobelt.
