200 FAUNA AND FLORA OF FALESTINE. 



I So. Neritina syriaca. 



1 8 1. Neritina jordani. Buttler. Sowcrby. Conch. 111., f. 49. 

 Found in the Jordan and its two lakes, Huleh and Galilee, but chiefly 



under the leaves of water-lilies in the Huleh. We never discovered it 

 living in the lower course of the Jordan. 



1 82. Neritina niiefwnii. Bourg. Test. Nov., ]3. 25. 



Abundant in almost every stream and spring throughout the whole of 

 Palestine, east and west. It attains its greatest size in the thermal springs 

 of the Ghor. 



183. Neritina bellardi. Mouss. Coq. Bellardi, p. 52, pi. i., f. 11. 



I have not had the opportunity of examining a type specimen ; but, 

 from the diagnosis, I believe this species to be that which is found in the 

 Jabbok and its affluents. It is certainly different from N. miehonii, as 

 may be at once recognised by an examination of its operculum. 



184. Corbictda saulcyi. Bourg. Moll. Nouv. Litig., p. 315, pi. xlv., 

 f 6—9. 



Long. 36, lat. 35, diam. 16-5 mill. 



This shell is at once distinguished from the next species by the coarse 

 and irregular striations which furrow the whole surface of the valves. 

 These in C. flnniinalis are fine and regular. 



Found in the Jordan. Dead valv-es by the shore of the Lake of 

 Galilee. 



185. Corbicnla JIuniiiialis. Miill. Verm. Fluv. Hist, ii., p. 205. 

 This species is not uncommon in the Jordan and Sea of Galilee. It 



is very variable in size, as may be seen from the measurements of two 

 specimens from the lake. 



Long. 17 — 27, lat. 20 — 28, diam. 16—21 mill. 



1 86. Corbicjila syriaca. Bourg. Locard. INIalac. Lac Tiberiade, 

 p. 29, pi. xxii., f. 22 — 24. 



Long. 19 — 24, lat. 17 — 21, diam. 11 — 16 mill. 



Found sparingly in the Lake of Galilee. Very common in the Lakes 

 of Antioch and Hums.
