1865. ] AND FLUVIATILE MOLLUSCA OF PALESTINE. 533 
21. Heuix Lenticuta, Fér. 
Near the coast. 
22. Henix nummus, Ehrenb. (=H. hedenborgi, Pfr.) 
Very abundant in the Nahr el Kelb, near Beyrout. 
23. Hexix sotirupinis, Bourg. 
Ceele Syria. 
24, Hexix prsana, Mill. 
Plentiful along the coast, to which it is strictly confined. Speci- 
mens from the north are very richly coloured, while from the di- 
strict near Gaza they are blanched and colourless in life. 
25. Hexiix caspitum, Drap. 
On the coast and the hills near it, in the north of Palestine. 
26. Hexix vARIABILIS, Drap. 
Very common on Mount Carmel, and with many variations of 
colours and size. The eastern specimens seem generally to be smaller 
than those of Europe. Probably several of the species not recog- 
nized by us may be referred to varieties of this widely spread and 
most variable shell. M.de Saulcy does not appear to have met 
with it, but perhaps distinguished it under some other name. 
27. Hexrx maritima, Drap. 
Found on the hills along the coast. From the study of a long 
series of intermediate varieties, I should feel disposed to diminish very 
greatly the number of described species of this variable group, 
28. Hexrx caperata, Mont. (= H. langloisiana, Bourg. ?) 
Common near Jerusalem. 
29. HELIx HIEROCHUNTINA, Roth. 
Takes the place of the preceding species in the Jordan valley. It 
may be at once distinguished by its red peristome and flattened spire. 
30. Hexiix TURBINATA, Jan. 
Scarce on the coast. 
31. Hewix apicina, Lam. 
In the north, on the dry rocks near the coast. 
32. HELIx CAMPESTRIS, Ziegl. 
Found on the high plateau of Moab and Eastern Gilead. 
33. HeLrx Protea, Ziegl. 
Common and variable from the coast to the southern deserts. I 
have many specimens corresponding to H. langloisiana of Bour- 
guinat, which appears to be only a strongly marked desert and 
blanched variety of the present species.
