VOLUTA Magorum. 
TAB. CCXC.—Fig. 3. 
Spec. Cuar. Ovato-fusiform, obtuse, costated, 
obscurely striated, with many plaits upon the 
columella. 
Syn. Voluta Magorum. Brocchi, II. 307, ¢. 4, 
ee: 
Tne spire of this Volute is longer, more oval, and 
blunter than that of V. costata; it has besides, 12 nar- 
rower and less prominent ribs in place of 9. The striz 
are conspicuous and distant about the base, but the 
principal character is the number of plaits upon the 
columella, which rise to the top of the left lip; the 
lower ones are large and terminate bluntly, while the 
upper ones are small and irregularly interrupted. 
The general outline of this shell is rounder than in 
V. costata, so that it might be distinguished even m 
imperfect specimens. I am not certain that I am 
correct in considering it the same as Brocchi’s V. Ma- 
gorum, the plaits on the columella of which differ some- 
what, according to the figure, and it is described as 
smooth: the state of preservation is also said to be 
different, as it appears to be changed into spar, so it 
probably belongs to another formation. I have not 
seen a Specimen. ‘The one before us was kindly sent to 
me from Barton, by the Rev. Mr. Bingley ; it is the 
only one I have seen.
