10. Helix saiicta. Bourg. Test. Noviss. Or., p. 15. 



Near Jerusalem. Mousson considers this only a giant variety of 

 H. ccUaria. The differences, however, appear constant, both in colour 

 and convexity. 



11. Helix nitellina. Bourg. Test. Noviss. Or., p. 16. 

 Scarce throughout the country. 



12. Helix protcnsa. Fer. Tabl. Syst., p. 40, No. 207. 

 Nablus. 



13. Helix cellaria. Miill. Verm. Terr, et Fluv. Hist, ii., p. 38. 

 In the north only. 



14. Helix jebusitica. Roth, in Malak. Bl., 1855, p. 24. 



Near Jerusalem, Sarepta, and Nazareth. Easily distinguishable from 

 H. sancta by its less regular and less delicate strlation, and by its much 

 larger umbilicus — and from the following species by its rounded umbilicus 

 and the less rapid increase of its whorls. 



15. Helix cBquata. Mouss. Coq. Bell. Or., p. 16, 55. 

 Only in the north, near the coast. 



16. Helix camelina. Bourg. Test. Noviss. Or., p. 14. 

 Near Nazareth, Jericho, and Jerusalem. 



17. Helix hicrosolyniitana. Bourg. Test. Noviss. Or., p. 13. 

 Not uncommon close to Jerusalem ; not met with elsewhere. 



18. Helix pulchella. Miill. Verm. Terr, et Fluv. Hist, ii., p. 30. 



We found a single specimen of this world-wide species under a stone in 

 the Plain of Acre. 



19. Helix conspurcata. Drap. Tabl. Moll., p. 93. 

 On the coast near Sidon. 



20. Helix erdelii. Roth, in Pfr. Mon. i., p. 205.
