25.. The Leeches of the Lake of Tiberias. 
By N. Annanpae, D.Sc., F.A.S.B. 
(Published by permission of the Trustees of the Indian Museum.) 
The Hirudinean fauna of the Lake of Tiberias is a poo 
one and may now be regarded as well known, for three Seperate 
collections from the district have agreed with one another. 
These three collections are (i) that made by Dr. Th. Barrois in 
1890; (ii) that made by Dr. Festa in 1893; and (iii) that made 
y myself in 1912. The two former were described by Prof. 
own collection includes specimens of three et one 
of which was not taken in the immediate vicinity of the lake, 
although doubtless it occurs there. I have found it ache 
to recognize the local form of one common species as a distinct 
race or subspecies. The species are— 
Placobdella catenigera (Moq.-Tand.). 
I found a large specimen under a stone in the stream that 
runs through the Wad-es-Semakh. It was full of blood and 
had probably just left a tortoise, for the species is parasitic on 
aquatic Chelonia. A very young leech possibly of this species 
was found under a stone at the edge of the lake near Mejdal. 
< catenigera is widely distributed in Eastern Europe and 
Western Asia. 
aemopsis sanguisuga (Linn.). 
Several specimens were obtained from ha village fountain 
at Kefr Kenna between Tiberias and Nazareth. The species is 
common in such situations in Palestine nite probably shares 
with Limnatis nilotica' the habit of entering the throats of 
animals and persons who drink incautiously at springs, causing 
thereby great discomfort and even dan . 
Herpobdella (Dina) lineata (O. F. Miiller). : 
This is the only leech at all common in the lake. It is 
discussed in the following note —
