to refer them to the var. conulus described by Professor yon Martens,’ 
but that shell is more elevated in the spire; and the differences 
between the present shell and G. Hophinsi are sufficient, in my 
opinion, to warrant its being considered a separate species. No trace 
of spirals can be detected in G. Fulton, and although 1 mm. less in 
diameter than @. Hopkins¢, it possesses one whorl more; it is also 
more conoid in the spire, and the whorls are flattened above ; the 
acute exserted keel runs up the earlier whorls margining the suture, 
a feature totally wanting in G. Hopkinst.

‘Shell narrowly umbilicated, trochoid, thin, solid, corneous, very 
finely striated, minutely granulated above and decussated with spiral 
lines below the periphery. Spire conical, slightly globose; suture 
margined, apex obtuse. Whorls 9, flattened above, a little swollen 
below, increasing slowly and regularly, the last not descending 
anteriorly, and scarcely dilated towards the mouth, with an acute 
pinched keel at the periphery, which is continued upwards above 
the suture. Aperture oblique, subquadrate; peristome thin, acute, 
slightly thickened, its margins distant, upper nearly straight, a little 
reflected, forming an angle! with the basal margin, cae is arcuate 
and well reflected; columellar margin dilated above .and partly 
covering the narrow umbilicus.”

Type in my collection. 
G. procera resembles G. eximia, Mdff., but is larger and wider at 
the base, the keel is more prominent and pinched, and the umbilicus is 
narrower; the surface is minutely granulated above and spirally 
striated below, features which are lacking i in G. eximia. G. phonica, 
G. eximia, and G. procera form a group ‘of which G. phonica is the 
smallest and @. procera the largest. Mr. Ponsonby possesses a specimen 
similar to the type. The species is now figured for the first time. 
Fig. 24 shows the granulated surface of the last whorl behind the 
peristome (enlarged).
