Stenogyra dtcollata is very abundant. The curious H.uautiliformis 

 (section Drepanosto)na) is found in the Italian Lake District. 

 Sicily has many forms pecuhar to itself, especially a group of very 

 strongly costate Clausiliae, C. syracusana, Gro/imamnana, now 

 made into a subgenus under the name of Siciliaj'ia. Corsica and 

 Sardinia have already yielded some distinct forms, and will 

 probably produce more when better explored. Even the small 

 islands, like Malta, Lampedusa, etc., have distinct species. Malta 

 has^ amongst others. Helix (Iberus) i>ieiife/is:s, H. ( Xerophila) 

 vieda, Clausilia oscitans, delicatcs and inamotica, and Cydostomus 

 vielitensis. In Lampedusa is found Clausilia Lampedusa;. 



C. The Hispano-Algerian Division. Possibly the Spanish Penin- 

 sula and Africa would be better separated, but there are so many 

 species, especially amongst the Macularia common to both, that 

 we are unwilling to multiply divisions for the present. In this 

 we have the direct opposite of the i\ustro-Turkish Division. 

 Clausilia and Buliminus are almost absent, whilst Macularia 

 is in immense numbers, 24 species out of 31. Leucochroa is 

 represented by several curious forms, especially in Morocco 

 (L. turcica, Mogadorensis, degejierans, &c.) Fruticicola, so abundant 

 in the rest of Europe, is comparatively scarce here, doubtless on 

 account of the dry climate and scarcity of deciduous trees. Cam- 

 pylcea and Pomatia also are almost absent. Xerophila, on the 

 contrary, is fairly represented. A large number of species oiCionella 

 (especially of the subgenera Azcca, Ferussacia, and Acicula, have 

 been described from Algeria, but it is doubtful how many are good 

 species. Witli regard to the Cyclostoi/iidce, this Division is 

 remarkable for possessing the only tv/o species of Leonia, niauiil- 

 la/is, common to Spain and Algeria, and scrobiculata, lately dis- 

 covered in Morocco, and the only Luropean Tudora, T. ferrugi/ica, 

 found in the Balearic Islands and at Gibraltar. A speciality of 

 this fauna, caused doubtless by the dry climate, is the prevalence 

 of white calcareous shells.
