Inliaculus, Schaufuss, in Patel’s Cataloge imd Systeme, p. 15, substituted 
as subgeneric name for Lia, Alb, 
Cylindrclla. 11. Crosse & P. Fischer have examined numerous preparations 
of the jaw and radula of species of this genus, and state that Cylindrclla and 
Macroceramus agree in having a very thin jaw, folded obliquely, and a radula 
with very oblique rows of teeth, which have the shape of ‘‘ palmettos.” They 
distinguish, according to the number of lateral and marginal teeth, four sec- 
tions of the genus Cylindrclla, of which C. bahamensis (Pfr.), elliotii (Poey), 
rosea (Pfr.), and maugeri (Wood) are the types. Journ. Conch, xvii. pp.
