*) Species similar to /Z. Bromnii Gray, but the shell is larger, thicker, 
less globose, with the incision as deep but much narrower.and linear; the 
produced columella is grooved with a broad shallow furrow, while in 47. 
Bromnü it has a deeply impressed line. — 'The form and size are inter- 
mediate between H. maxima and H. Bromniü. (Adams l. c.)
