163. Mclania rothiana. Mouss. Coq. Rec. Roth., p. 61. 



We obtained several dead specimens of this shell by the Sea of Galilee ; 

 I am more than doubtful of its specific value, believing it to be merely an 

 elongated form of J/, tubcradata ; but M. Lortet, a much better judge, 

 considers it distinct. 



164. Ulclania gcnimnlata. Reeve. Conch. Icon., vol. xii., Melania, 

 pi. xiii., sp. 86. 



In the Nahr el Kelb. Always a deep brown-black, and differing from 

 M. tiibenidata in the absence of the longitudinal ridges and tubercles on 

 the spire. 



165. Melania rnbro-punctata. Tristram. P. Z. S., 1S65, p. 541. 



Long. 21, diam. 5 mill. ; altera 17 long., '^\ diam. 



Lives buried in the sand, in fountains near the Dead Sea. 



Had I not consulted more experienced naturalists than myself, I 

 should have felt disposed to have included this as a delicate and very 

 beautiful variety of the variable HI. tuberadata. The distinctive 

 characters are the extreme smallness of the aperture and the sudden 

 termination of the longitudinal sculpture, which does not extend to the 

 lower whorls. 



166. Melania judaica. Roth. Malak. Bl. ii., p. 53. 



167. Melanopsis biiccino'idea. (Oliv., Voy. I., p. 297.) 



Very abundant in almost all the streams of Palestine, and found sub- 

 fossil in the old marl-deposits by the shores of the Dead Sea. There is a 

 distinct variety peculiar to almost every district. 



Var. A, from the Nahr el Kelb, near Beyrout, is horn-colour, with 

 three dark brown bands. 



Var. B, from streams near Engedi and other streams flowing into the 

 Dead Sea, is much larger than any other specimens I have seen, and may 

 be at once recognised by a compression on the right side of the peristome, 

 near the columella. It is rarely black, but of a rich brown colour, and the 

 inside of the mouth a pale purple. It may be hereafter separated as a 

 distinct species. 



\-dx. C, from the waters of Merom and the Lake of Galilee, is very
