Avill now return to the Austro-Tuikish Division. In the genus 

 Helix the section Carthusiajia is principally found here, and 

 Cauipylcca, though also tolerably abundant in Italy, has more 

 representatives here than elsewhere. Levantina is exclusively 

 found in Abia Minor and Cyprus, and Poinatia may be considered 

 as chiefly Austro-Turkish. The only Pala^arctic species of 

 Tanatellina occur near Jerusalem. Xerophila, though well repre- 

 sented here, is perhaps more of a western subgenus, and Iberus 

 and Macularia are almost absent. On the other hand, of the true 

 Zonites all but one (Z. algirus) are peculiar to this Division, and 

 Mesomphix (subgenus of Hyalina) has some fine forms m the 

 Caucasus. 



Central Asia is as yet imperfectly known, and it is doubtful 

 where the boundary between the Northern and Mediterranean 

 Regions should be fixed. Our knowledge of it is principally 

 derived from V. Martens' " Fedtschenko's Reise in Turkestan," 

 which, notwithstanding its German title, is unfortunately printed 

 in the Russian language, so that only the Latin diagnoses, list of 

 species, and the plates are available for the vast majority of 

 European naturalists. The presence of the Palaeotropical and 

 Australasian genus Alacrochlamys is remarkable, as is also that of a 

 species of Cyclotus. There are 5 species of Buliminus. Along 

 Vvith these are many northern forms, Hyalina nitida and fulva, 

 Helix costata, Cionella lubrica, etc. 



B. The Italian Division (including the South of France). This 

 may be considered as occupying an intermediate position between 

 the others. The genus Clausilia, so abundant in the Austro- 

 Turkish Division, is, as we have seen, well, but not commonly, 

 represented. Buliminus has but few species. The s.g. Canipyltea 

 is abundant, and we now come upon many of the foi ms character- 

 istic of the western portion of the Mediterranean, Macularia for 

 instance. Iberus belongs almost exclusively to this Division.
