Helix protea, Ziegl. Plain of Judaea, at Bir es Sebi, Tell el Milh, etc. ; 

 Gaza. Very variable in colouration, 



H. vestalis, Parr. Gaza. 



H. tuberculosa, Conrad. First found by Professor Hull, and again in 

 two different places by me in the plain of Judaea, between Tell el Milh 

 and Tell Abu Hareireh. A very peculiar trochiform species, with the 

 whorls prettily striated and mitred, giving a spirally laminated appearance. 

 Canon Tristram speaks of it as very rare, and ' the most peculiar and in- 

 teresting Helix in Palestine.' 



H. Ledereri, Pfr. Yebnah, between Gaza and Jaffa. Similarly marked 

 as the last, but thoroughly depressed instead of trochiform. 



H. Seetzeni, Koch. Widy 'Arabah ; Sinai, at Wady Barak ; abundant 

 in Judaea, often covering the stems of Anabasis. 



H. candidissima, Drap., van minuta. Sinai, near 'Akabah ; Widy 

 Ghurundel, in Edom ; Jordan ; Bir es Sebd. 



H. prophetarum, Bourg. Wddy Ghurundel, Edom ; Wady 'Arabah, 



H. Boissieri, Charp. Judaea. A large solid species thinly distributed 

 on rich land between Bir es Sebci and Gaza. 



H.filia, Mouss. Widy 'Arabah, in several places ; Wady Ghurundel, 

 in Edom ; Ghor es Safieh. Canon Tristram found it ' extremely scarce, 

 only in a few localities near the Dead Sea.' 



H. spiriplana, Oliv. Jebel Abu Kosheibeh and Mount Hor ; Wady 

 Ghurundel, in Edom ; and between Jericho and Marsaba. Jerusalem, at 

 the ruins of St. John's Hospital. { = H. guttata, Bourg.)

H. Olivieri, Feruss. Jericho, by the Jordan ; Ghor es Safieh, abun- 

 dant dead amongst drift on the shore of the Dead Sea. Has not, I 

 think, been gathered in Palestine before. 



Helix bcBtica, Rossm. Drift on the shore of the Gulf of 'Akabah. 

 Derived from the Midianitish side. 



Bulimus cadmeus, Pfr. Dead Sea drift ; Widy Ghurundel, and else-
