 large variety of Macrocheilus ventricosus, although it is some- 

 what more globose, and the spire is proportionately less prom- 

 inent than usual in that specif s. XV.

Macrochilina ; generic name proposed by Bayle in 1880, 

 Journal de Oonchyliologie, [3] Vol. 1, 19, to be used instead of 

 Macrocheilus, above, because the latter name has been pre- 

 occupied by Hope. (S. A. Miller's Oat. Pal. Foss. Supplement, 

 2d Ed. 1883.) 



Besides the above mentioned, Miller's Oat. refers to more 

 than a dozen other species of this widely distributed and long 

 lived genus of Gasteropod ishells.
