Bulinine | 
Shell ovate or oblong, sinistral, Physa-shaped or narrowly elongate, turreted, 
frequently scalariform. 
This subfamily includes practically all Ethiopian species that were 
formerly regarded as Physxe. They differ from the true Physide, 
however, in the structure of the radula, which is asin Planorbis. In 
addition, the animal lacks the digitations of the mantle possessed by the 
Holarctic Physx, and has a pseudobranch. 
The subfamily Bulinine appears to be restricted at present to 
Australia, Oceania, New Guinea, Celebes, Japan, India, the Ethiopian 
and Malagasy Regions, the Mediterranean Subregion as far east as 
Mesopotamia, and the Antilles. Platyphysa Fischer (1883, ‘Manuel de 
Conchyl.,’ p. 510) was proposed as a group of Bulinus for Physa prin- 
sepit Sowerby, a large-sized form from the Eocene of India; its correct 
place in classification 1s uncertain, but it may equally well be one of 
the Physidee. 
The following are the genera and subgenera at —— recognized 
among the Bulinine. 
Bulinus O. F. Miller. With Pyrgophysa Crosse, Ameria H. Adams, Glyptophysa 
Crosse, Physastra Tapparone-Canefri, and Isidorella Tate as subgenera, some of 
which may prove untenable upon further study. The African species appear all to 
belong to Bulinus proper and to Pyrgophysa. See p. 135.
