1 86 FAUNA AND FLORA OF PALESTINE. 



6i. Helix filia. Mouss. Coq. Voy. Roth., 1861, p. 26. 



This beautiful desert species has strong affinities both with H.pro- 

 phciarnin and H. boissieri. It is extremely scarce, and is found only in a 

 few localities near the Dead Sea. 



62. Helix cariosa. Oliv. Voy. ii., p. 221, pi. 31, f. 4. 

 E.xtremely abundant in the mountain districts of Western Palestine ; 



not observed in the east. The three varieties, (i) amphicyrta, (2) nazar- 

 ensis, (3) ci'assocariita, are easily recognisable. The third is the prevail- 

 ing type in the north, distinguished by its depressed spire and broad 

 flattened keel. About Nazareth it gives way to the second variety, 

 rounder, with the keel more compressed, but still the spire depressed. 

 Specimens about Jerusalem and Carmel partake of the character of the 

 first variety, with elevated spire ; while at Hebron, the southern limit we 

 observed for this shell, the northern form crassocarina reappears un- 

 changed in the slightest particulars. 



63. Helix guttata. Oliv. Voy. ii., p. 334. 

 Dead Sea. 



64. Helix eremophila. Boiss. Reeve. Conch. Ic, vii., No. 956. 

 Southern Desert. 



65. Helix ccssareana. Parr. Mouss. Coq. Or., p. 34, 44. 

 Abundant in the plain of Sharon and about the Sea of Galilee. The 



specimens from Gennesaret are much larger and more richly marked than 

 those from Judaea. 



66. Helix spiriplana. Oliv. Voy. Lev. i., p. 415, pi. 17, f. 7. 

 (^ — H. guttata, Bourg.) 



Generally distributed, but not numerous, in the higher grounds of 

 Southern Palestine, and not found in the same localities as the preceding. 



67. Helix viasadcr. Tristram. P. Z. S., 1865, p. 535. 



Diam. maj. 30, min. 25, alt. 14 mill. 

 Apert. diam. maj. 13, min. 11 mill. 



Found on Sebbeh, the ancient Masada, and the most barren and sterile 

 mountains from thence to Jebel Usdum, the salt-mountain. The deep and
