Asiatic Society of Bengal, April 1.—A. d’Orchymont : 
Hydrophilidz from the Lake of Tiberias. The hydro- 
philid beetles are represented in Dr. Annandale’s col- 
lection by sixteen specimens, including examples of 
six species.—M. S. Ramaswami: Note on leaf-variation 
in Heptapleurum venulosum, Seem. This paper illus- 
trates the remarkably wide range of leaf-variability in 
the above species. The author shows that the method 
used in ‘‘ The Flora of British India” for differentiat- 
ing between the two sections of the subgenus Euhepta- 
pleurum, namely, the simply digitate or twice digitate 
character of the leaves, is incorrect so far as this 
species is concerned.—Dr. W. M. Tattersall: Amphi- 
poda and Isopoda from the Lake of Tiberias. Three 
species of Amphipoda and three of Isopoda are in- 
cluded in Dr. Annandale’s collection. It seems prob- 
able, on comparing these with the collections made 
by Barrois and by Festa, that the complete fauna of 
the Lake of Tiberias is now known, so far as the 
aquatic and semi-aquatic representatives of the two 
groups are concerned. Of the species in the collec- 
tion, one Amphipod, G. syriacus, and one Isopod, 
A. soxalis, are endemic and have not’so far been found 
outside Syria. The remaining species are distinctly 
‘* Mediterranean ’’ in character, though one (Orchestea 
platensis) is known also from the Atlantic coasts of 
America.
