last whorl, mentioned by some of the authors quoted above. Hervier (Journ. de Conch. 1899, 

 p. 326) considers this to be one of the leading characters for distinguishing this species from 

 the preceding one, though Kiener makes no mention of them and Hervier (1. c. p. 320) says 

 to have received specimens without nodules. Kobelt (1. c.) inclines to the opinion that both 

 species ought to be united.

The specimen from Stat. 50 is very young, one from Stat. 282 very fine with a brown 

 epidermis. Tryon nor Kobelt quote a book where Pease should have published his description, 

 if it be a MSS. name, Tryon should be quoted as author, as Pace (Proc. Mal. Soc. Lond. 

 Vol. V, p. 106) has done. The original specimens were from the Paumatos-isles; the species 

 has also been recorded from the Feejee-isles.

The specimen from Stat. 60 is marbled, that from Stat. 53 white, both with redbrown 

 spiral lines. Though the riblets of the upper whorls are wanting, they sufficiently agree in other 

 respects with the descriptions and figures. Von Martens (Moll. Mauritius, p. 228) emits the 

 opinion that this species should be identical with Kiener's Pleurotoma nitida and locates it in 

 Dapliuclla. I have foliowed the opinion of the majority of authors in placing it in Columbella, 

 the name nitida, if belonging to this species, can have no priority, on account of Col. nitida Lam. 

 from the West-Indies.

Shell oblong-ovate, with moderately acuminate spire, yellowish-white, with a narrow

 aperture, forming on last whorl a peripheral zone, moreover there are a few spots of the same 

 colour near the base. Whorls 8, of which about 3 form a smooth nucleus ; postnuclear whorls
