a layer of enamel, inner lip short and heavy. Length of shell, 9.2; 

 of aperture, 2.5; diameter, 3.3 mm. U. S. Nat. Mus. Cat. No. 

 108375. 



Off Georgia, 10 specimens. 



The specimen described by Stimpson and figured by Tryon is 

 young; the brownish bands are not constant in fresh specimens and 

 fade in the cabinet. A description is therefore given of the adult 

 shell, which agrees with specimens identified as M. oleacea from Vine- 

 yard Sound, by Professor Verrill. 



MELANELLA CONOIDEA Kurtz and Stimpson 



Eiilima conoidea Kurtz, and Stimpson, Proc. Boston Soc. Nat. Hist., vol. 4, 

 p. 115.— Tryon, Man., vol. 8, p. 273, pi. 69, fig. 40, 1886. 



Shell small, solid, polished, white, with a blunt apex, slightly bent 

 spire, and about eleven whorls; suture obscure, with an over-glaze; 

 the whorls enlarge rather rapidly; there is no perceptible sculpture; 

 base evenly rounded; aperture short, sublunate, the outer lip simple, 

 flexuous, the body with a layer of enamel, the inner lip thickened. 

 Length of shell, 9.5; of aperture, 2; diameter, 3 mm. U. S. Nat. Mus. 

 Cat. No. 108026. 



Off Fernandina, one specimen; South Carolina, Kurtz. 



This is very much like M. oleacea but the last whorl is not so much 

 expanded, the sides are flatter, and in the adult the carination of the 

 last whorl mentioned by Stimpson, a feature of immaturity, does 

 not appear. 



MELANELLA PENNA, new species 



Shell small, conical, smooth, polished, creamy white with a blunt 

 apex and eight flattened whorls; suture obscure, appressed, lightly 

 over glazed; surface without sculpture; aperture semilunate, outer 

 lip simple, somewhat flexuous, body with a layer of enamel, inner lip 

 slightly concave, with a perceptible umbilical depression behind it, 

 the base evenly rounded. Length of shell, 5.7; of aperture, 1.5; 

 diameter, 2 mm. U. S. Nat. Mus. Cat. No. 108032. 



Off Fernandina, five specimens. 



Tliis species appears to be nearly related to M. gracilis C. B. Adams, 

 1850; not of Jeffreys, 1848. 



MELANELLA RECTIUSCULA Dall 



Eulima {Liostraca) rectiuscula Dall, Trans. Wagner Inst., vol. 3, p. 160, 

 1890. 



Shell small, slender, polished, white, with a swollen blunt nucleus 

 of two whorls and ten subsequent slightly convex whorls; suture dis- 

 tinct, shallow, not glazed over; sculpture only of faint incremen- 

 tal fines; base elongately rounded, imperforate; aperture subovate, 

 outer lip simple, slightly convexly arcuate, inner lip short, slightly
