TERRESTRIAL AND FLUITATILE MOLLUSC A. 189 



82. Biilinuts labrosns. Oliv. \'oy. Lev. ii. 222, p. 31, f. 10. 



The finest and most characteristic shell of Palestine. It is found 

 generally concealed in small fissures of the limestone rocks, sometimes 

 under stones, throughout the whole of Western Palestine, as far as the 

 edge of the Ghor or Jordan valley, but not beyond. It is most abundant 

 near the coast, where it attains its greatest size. A very small variety is 

 found in the southern wilderness. 



83. Bttlimus carnciis. Pfr. Phil. Abbild. ii., pi. 4, f. 5. 



This beautiful shell takes the place of the preceding species in the 

 basin of the Dead Sea towards the south ; but we never found it north of 

 Engedi, nor on the east side. It is most plentiful about the famed rock 

 of Masada, the modern Sebbeh. We brought a considerable number 

 home alive, which are now depositing their eggs, and feeding on succulent 

 plants. It is impossible, after observing a large series, to have any hesi- 

 tation in separating B. cariicns specifically from B. labrosus. The elon- 

 gated form, the mouth proportionally less than half the size of the other 

 species, and circular instead of being extended towards the right, the 

 solidity of the peristome, and the callosity largely extended over the last 

 whorl, at once distinguish every specimen ; nor have I ever detected any 

 intermediate forms. 



The typical B. carneus of Dr. Pfeiffer is from Lycia. I have not been 

 able to compare my specimens with the type, though they appear to 

 coincide exactly with the diagnosis and the figure. It is possible that our 

 Dea Sea species may be distinct. 



84. Bulimus alepi. Fer. Prodr., p. 41 8. 



Generally difflised, but scarce in number of individuals. Collected 

 near Jerusalem and by the Dead Sea. 



85. Bitlimiis syriacus. Pfr. Symb. iii., p. 88. 

 Extremely abundant in certain localities of the Lebanon. 



86. Bulimus sidoniensis. Charp. Reeve. Conch. Ic, v., pi. Ixiii., 

 No. 433. 



In the plain of Phoenicia and the neighbouring hills.
