Hamulus faloatus (Conrad). 



Dentalium jalcatum Conrad, Am. Jour. Conch., V, 44, pi. 1, fig.s. 12, 16, 1869. 

 The type of Conrad'.s genus Falcula, Am. Jour. Conch., VI, 77, 

 where he refers to it as Dentalium? hamatus is truly an error, for in Vol. 

 V he refers to a similar species, D. hamatum Forbes, found in India. 

 The genus is based entirely upon internal casts of a Hamulus, probably 

 H. onyx Mort. Also specimens figured by Whitfield, pi. 20, figs. 16, 17.
