1865, vol. 34, pt. 2, pi. 9, f. 4) in pi. 153, f. 7, and variabilis, 
var. turrita of tile same (do. f. 6) in pi. 153 : f . 6 ; f. 5 of the 
same plate is closely allied to the latter, and perhaps all three 
are abnormal forms of M. baccata. 
1 Compare Gould’s Paludina petrosa (Pr. Bost. N. H. vol. 1, 
p. 144 ; Otia, p. 191) from Birmah. 
2 Pr. Zool. 1852, p. 127. The worn type is very like our 
figure of decussata, but is not that species. 
3 Pr. Zool. 1854, p. 92. 
4 In addition to those indicated A. Dolioides, from S. America, 
has been wrongly referred to Bombay by Beeve, and A. Luzonica 
of Beeve with A. Sumatrensis of Philippi, attributed to Ceylon 
by Dohrn ; these localities have not been confirmed. The A. 
pygmaea of Becluz, from Bombay, if not an immature shell, is 
probably the Amphibola referred to by Blanford as very close to 
his A. Birmana. 
5 Compare the A. hepataria of Beeve (C. Icon. Amp. f. 77). 
6 Conch. Icon. Ampullaria. 
7 Martens assigns to this long-forgotten species the P. fallax 
of Frauenfeld and Beeve (C. Icon. Pal. f. 51), and agrees with 
Morch and Troschel as to the identity, also, of Swainson’s P. 
carinata (Zool. 111. ser. 1, pi. 98) from the Ganges; this last is 
referred by Frauenfeld to Bemossii. The type of Beeve' s mela- 
nostoma (very badly figured) in 0. Icon. Pal. f. 27, is, at most, a 
variety of dissimilis.
