Calcutta. 

 Asiatic Society of Bengal, July 2.— F. F. Laidlaw : 



Noteonthedragonfliesof Syria and the Jordan Valley. 

 The dragonflies of Syria and the Jordan Valley are 

 still imperfectly known, but at least two geographical 

 elements may be distinguished among "them- a 

 Mediterranean element, and a tropical one, African 

 in its main features, but also showing certain affini- 

 ties with the Oriental fauna.— Dr. N. Annandale and 

 S. W. Kemp : The Crustacea Decapoda of the Lake 

 of Tiberias. Three species of Decapoda are known' 

 from the Lake of Tiberias and its immediate vicinity, 

 viz. the crab Potamon potamios, and the prawns 

 Atyaephyra desmarestii and Typhlocaris galilea. The 

 last occurs only in one small isolated pool, and is 

 remarkable on account of its degenerate eyes and 

 uniform white coloration, as well as for certain struc- 

 tural characters which separate it from all other 

 Caridea.
