IANTHINA globosa.
Globular Oceanic Snail—middle figures.
I. testâ ventricosâ, basi productâ; aperturâ longiore quam latiore; labio exteriore leviter emarginato.
Shell ventricose, the base lengthened; aperture longer than broad; outer lip slightly emarginate.
The notch, which in I. fragilis extends the whole length of the lip, in this, is very slight, and nearly central. Mr. Dubois has enabled me to figure it from specimens in the greatest perfection; it is much less common than the last.
