VOLUTA costata. 
TAB, CCXC.— Figs. 1, 2, and 4. 
Spec. Cuar. Ovato- fusiform, acute, costated, 
striated, with about three plaits upon the co- 
lumella. 
Syn. Voluta costata. Brander, f. 45. 
Anove twice as long as wide, with nine coste upon 
each whorl; the coste are broad and obtuse, a little 
swelled at their upper ends: they are crossed by strie 
that are least conspicuous about the middle of the body. 
The beak is short and very little curved: the columella 
is furnished with three folds, of which the lowest is 
much the largest: the mouth is very oblong, it has both 
lips smooth. The length of the spire is liable to va- 
riation ; it generally consists of seven turns. 
This is not a very common shell. ‘The specimen, 
fig. 4, enriches the select cabinet of Miss Dent; it is 
the largest I have seen, and has the mouth well pre- 
served. Fig. 1 represents a specimen in the possession 
of Miss Salisbury ; the strize upon the surface are re- 
markably neat. For the shorter variety, fig. 2, Tam 
indebted to the kindness of Miss Dent: all are from 
Barton.
