MOLLUSC A. 



In addition to the above total, Mr. McAndrew collected a number of 

 species, which are as yet undescribed, from the Gulf of Suez. These 

 are being dealt with in the current numbers of the Annals and Magazine 

 of Natural History. 



LAND AND FRESH-WATER MOLLUSCA. 



These have been kindly named for me, with the exception of half-a- 

 dozen, by Canon Tristram. The other six I have had determined by 

 Mr. G. B. Sowerby. 



Sinai is poorly supplied with molluscs, and it was not till I reached 

 Petra and crossed the 'Arabah watershed that any variety appeared. 



A good gathering was made amongst drift shells on the margin of the 

 Dead Sea, a little east of the swampy embouchure of the Tufileh river. 

 All were dead and beached, but often in good preservation, being killed 

 the instant they reach the salt sea. These may, I think, be all safely 

 referred to the Ghor es Safieh. The stream comes from the mountains 

 and over rocks immediately into the Gh6r, where it has a quiet course of 

 a few miles. The shells I speak of are too fragile to have travelled, 

 except a very short distance, and are accompanied by other Ghdr de- 

 posits. 



Succinea elegans, Risso. This species (determined by Mr. Sowerby) 

 was very abundant in a dead state in the drift on the south-western edge 

 of the Dead Sea. Canon Tristram does not mention this species as 

 having been found in Palestine. 



Helix joppensis, Roth. Ghdr es Safieh and Judaean plain west of the 

 Ghor. In the Widy 'Arabah, between 'Ay{in Buweirdeh and the Gh6r. 

 Canon Tristram writes me, ' Probably only a variety of H. csespitum, 

 Drap.' It is much larger. It is in his list, but without locality. 



H. syriaca, Ehr. Gaza. 



H. ccsspitum, Drap. Petra and Widy 'Arabah, near the Gh6r. Found 

 in the north of Palestine near the coast. 



H. hierochuntina, Roth. By the Jordan, below Jericho.
