40 BULLETIN OF THE 



identical with the A. depressus of Libassi, which is unknown to me, and with 

 the A. noce J. Sowerby, from the Red Crag of Britain, an opinion which I 

 cannot confirm after careful comparison of specimens. The A. noce is a very 

 ponderous and much larger species, with a much more prominent and hori- 

 zontal fold on the columella, as well as a thickened and striated outer lip.

Habitat. Buzzard's Bay, Mass., to Florida, Cuba, and Santo Domingo, in 

 2-63 fms. Pliocene of Florida. Orbigny's name is preoccupied by Lea for a 

 fossil species (1833), but there is practically no doubt that his shell and 

 Adams's are identical. They vary from pure white to trifasciate with rose or 

 livid brown, usually faint and nebulous. The height of the spire, elevation of 

 the nucleus, and extent of shell covered by the punctate lines, vary in the 

 different specimens. Usually the spire is rather elevated, the nucleus some- 

 what depressed, and the punctate grooves cover about half of the last whorl. 

 There may be one or several subsutural lines, the middle of the whorl is gen- 

 erally smooth and free from lines, and the anterior part crowded. The 

 northern ones are variegated like those from the Antilles, but the latter are 

 more frequently bright colored. The very young, like those figured by 

 Adams and Orbigny, are usually white or translucent. The colors, when 

 banded, are nearly always rather nebulous, and the number of bands never 

 exceeds three, the anterior one most often absent. The shell is always thin, 

 and often nearly translucent. Actceon turritus Watson (Chall. Gastr., p. 628, 

 pi. xlvii. fig. 1) should be compared with this species, though the figures 

 are not very similar ; the locality, Culebra Island, W. I., is suspicious.

This differs from A. delicahis by its stumpier form, coarser and ruder sub- 

 cancellate striation, more prominent fold on the columella, and particularly by
