tains the name Rhodonyx [Zool. Rec. x. p. 169] for ruhescens, as a dis- 
tinct sub -genus, on account of the form of the shell. 
Pellicula appendiculata (Pfr., as Succinea) is placed by Bland 
& Binney in Ampliihulima., on account of the jaw and radula ; 
Ann. Lyc. N. York, x. p. 343, and P. Ac. Philad. 1874, p. 42, pi. viii. 
fig. 6, genitals, fig. 5. P. Fischer discusses depressa ("Rang) and 
appendiculata (Pfr.), describing the jaw, radula, nervous system, and 
genital organs of the former, and placing both in Amphibulima, as a 
distinct sub-genus, Pellicula. He remarks that this, in the Bulimulida; 
[Orthalicidce']^ is analogous to Homalonyx among the Succineidce \_Elas- 
mognatha'], Tind to Sti'ehelia among the Glandinidce \_Agnatlia7\. J. de

Homalonyx. To this genus belong, from examination of the radula, 
the so-called Amphibulima felina (Guppy), probably not specifically 
distinct from unguis (Fer.), and Succinea, {Pellicula) convexa (Martens).
