Syria and recently recorded by Dr. Annandale from Mesopotamia 
and (ii) B. rubens, a species widely distributed in Italy, Sardinia, 
Greece, Algeria, Syria and probably in Upper Mesopotamia. 
Bithynia badiella, Parreyss. 
1919. Bithynia badiella, Annandale, op. cit., p. 162. 
In addition to the specimens reported on by Dr. Annandale 
there is a shell in the collection made by Dr. C. L. Boulenger from 
the area between Nasiriyeh and Hama Lake, Lower Mesopotamia. 
These specimens agree closely with the specimens from Palestine 
and Syria in the Indian Museum collection. 
Bithynia rubens (Menke). 
1892.. Bithynia rubens, Kobelt, op. cit., pp. 70,71, pl. cxxxvu, fig. 806. 
Specimens of this very variable species collected by Dr. 
Boulenger and Dr. Bowell at Basra agree with Kobelt’s figures and 
with the specimens in the Indian Museum collection from Damas- 
cus. 
Nevill! gave names to a number of well characterized forms 
of the species from various localities and the specimens he marked 
are in the collection of the Indian Museum. As he did not 
describe these forms and some of them have since been described 
by Preston under other names, Nevill’s names will have to be taken 
as nomina nuda only, but the whole question is too complicated to 
be dealt with here. 
Genus Amnicola, Gould and Haldemann. 
Subgenus Alocinma, Annandale and Prashad.

1920. Alocinma, Annandale Rec. Ind. Mus., XIX, pp. 42, 43: 
Dr. Annandale and I recently proposed this subgenus for 
certain Indian and Persian species hitherto assigned to the genera 
Bithynia aud Amnicola, We regarded this subgenus as being of an 
intermediate character between 4 mmnicola s.s. and Pseudamnicola, 
both of which also must be considered as subgenera only. Re- 
cently Dr. Annandale has pointed out that ‘‘ Bythenia ejecta,”’ 
a species described by Mousson from Lower Mesopotamia, also 
belongs to this subgenus. 
Amnicola (Alocinma) ejecta (Mousson). 
1874. Bythinia ejecta, Mousson, op. cit., p. 40. 
A few of the specimens in Dr. Boulenger’s collection from the 
banks of the Euphrates at Nasiriyeh and at Feluja agree with 
Mousson’s description and are, therefore, assigned to his species.
