187. Cyrciia crassula. Mouss. Reeve. Conch. Icon. Cyrena, 

 sp. 72. 



Adonis river. Litany river, etc. Jaffa.

 Wady Kadisha, Lebanon. 



189. Uuio tenuinalis. Bourg. Voy. Mer Morte, p. ;6, pi. 3, f. 4. 

 This is the common Uuio of the Lake of GaHlee, and I found it also 



in the Litany (Leontes) river. The Uuio jordaiu'iiis, Bourg., seems to 

 be only a thinner and shorter variety of U. terininalis. I have obtained 

 so many intermediate specimens that it appears to be impossible to 

 separate the two. U. ici inijialis also seems to be identical with the 

 U. digiiatiis, Lea, from the Tigris, as I find on comparison of type 

 specimens in Mr. Cuming's collection. 



190. Unio dclcsserti. Bourg. \^oy. Mer Morte, Moll., p. "]•]. 



In the Zerka or Crocodile river, in the Plain of Sharon. Found by 

 M. de Saulcy near Jaffa, in the same plain. 



191. Unio micJionii. Bourg. Voy. Mer Morte, p. 74. 



In the Zerka or Crocodile river. Figured by Bourguinat from the 

 neighbouring streams of Jaffa. Appears to be but a variety of the 

 U. marginalisy Lamarck, a variable species found in India, Mauritius, 

 and China. 



192. Unio saulcyi. Bourg. Voy. Mer Morte, p. 74, pi. iii., 

 f. 1-3- 



From the Kishon. Found by M. de Saulcy in the streams near Jaffa. 

 This species is very like U. luosalensis, Lea, from the Tigris, if indeed it 

 be not the same species. 



193. Unio simonis. Tristram. P. Z. S., 1865, p. 544. 



Long. 66, lat. 44, diam. 32 mill. 



This shell is found in the Jordan, the Sea of Galilee (where it reaches 

 its greatest dimensions), the Orontes, and the Leontes (Litany). Its 

 rotundity, thickness, solidity, and the brilliant rosy tint of its nacreous
