BULIMULUS. 239 
Species of Leptomerus, B. limneoides, Fér., and of two other allied species, B. frater- 
culus, Fér., and B. sepulcralis, Poey [described by Binney, Ann. Lyceum N. York, x. 
BP 847 (1873), xi. p. 186, t. 16, figg. A, B (1875), and by Dr. Pfeffer, in Strebel’s 
Beitr. Mex. Land- und Siissw.-Conch. v. p. 56, t. 13. fig. 1], exhibit the distinctive 
character of this genus. As regards Peroneus, the radula of the Mexican and 
Californian species, as well as that of the typical species from Chili and Bolivia, has 
net yet been examined so far as I know; one S.-American species, however, B. fama- 
tinus, Doring, from the Argentine Republic, which may belong to this subgenus, has 
the radula and jaw of Bulimulus, according to the description given by Déring, Boletin 
de la Acad. de Cordoba, iii. p. 64 (1879).
