gers College, but is of still larger size and so characteristic in some of its 
features in which it differs from that one that I have concluded to notice it 
under a separate head, hoping that other specimens may be found to verity 
it. The fragment consists of the principal volution and a portion of the 
next above, the anterior beak having been broken near its upper part. The 
volutions are somewhat rounder than are those of /. Hector, the angu- 
lations being less distinct and the vertical folds more subdued. Both of 
these features, however, might result, at least in part, from the excessive 
flattening of the cast. The spiral lines, however, although the normal 
number possessed by the typical form are present and retain very nearly 
their relative position, are continued over the entire surface, both above and 
below the angulation of the whorl, with two intermediate finer ones between 
each of the principal lines; the finer lines are also continued below and 
upon the anterior beak as far as that portion is preserved. In the prelimi- 
nary examination of the species I had erouped this with the specimens of F. 
(N.) Hector, considering it only as a crushed specimen of that species pre- 
serving the markings ina more perfect condition. But on separating the 
largest individual of that one from the matrix, I find the fine transverse 
lines of growth perfectly preserved, without a vestige of spiral lines on the 
upper surface of the volutions, convincing me that this can scarcely be the 
same species. I therefore indicate it as above. The locality and geological 
position is the same as in that case.

Plate xxiv, Figs. 6, 7. 
Shell small, elongate-oval, or short-fusiform in general outline, spire 
forming one-half of the entire length, the body whorl large and termi- 
nating in a short beak. Volutions extremely ventricose, almost inflated, 
with deeply marked suture lines between them. Apical.angle about 45°. 
Aperture large, broadly ovate and terminating below in a short, narrow 
canal. Volutions crossed by closely arranged, rounded, vertical folds, 
which are confined to the upper two-thirds of their surface, becoming 
obsolete a little below the largest part, and are separated by narrow con- 
cave interspaces; twelve to fourteen of the folds may be counted on each
