X. ASIA MINOR. 



A. MAINLAND. 



Our knowledge of the Mollusca of Asia Minor dates as far back as 

 1839, when a collection of these creatures was made by Dr. Erdl and 

 Dr. Roth, which was described by the latter in " Molluscorum species, 

 Dissertatio Inauguralis." Other contributions were made by Mousson 

 (Coquilles terrestres et fluviatiles recuellies par le Prof. Bellardi, 1854); 

 Pfeiffer, in Malak. Blatter, 1857 ; Issel, in Ann. Mus. Civ. Genova, 

 1877; Naegeli, in Nachrbl. Deutsch. Malak. Gesellsch., 1894; and 

 quite recently by Sturany, in Sitz. Ber. K. Akad. Wiss., 1902, cxi. 



One of the most striking features of the Molluscan fauna of this 

 region is the number of species of Zo?ntes, which further south are 

 replaced by the genus Leucochroa. 



The occurrence of Vitrina conoidea, Mart., on Mount Olympus 

 in Asia Minor, as recorded by Bourguignat, '^' and confirmed by 

 Sturany '"' is certainly remarkable. The shell was originally dis- 

 covered in Tuikestan, and if the Olympus specimens are correctly 

 identified, the species may be assumed to exist in other places in the 

 intervening countries ; for the absence of intercourse would discount- 

 enance the theory of introduction to the one place or the other.
