The type of Angellum cuneatum is numbered 8815 in the Faber 
collection at Chicago University. It is labelled as coming from Rich- 
mond, Indiana, and lithologically appears as though it had come 
from the Whitewater member of the Richmond. The specimen 
has been so strongly carved by some one who desired to clean the 
specimen, that its present form is more manufacutred than natural. 
This is true especially of the part immediately anterior to the beak 
and of that part of the anterior margin where a cast of an anterior 
muscular scar has been carved out in a very unnatural location, far 
below the position which it must have occupied. 
The type evidently is a cast of the interior. The beaks appear 
to have been small and narrow. An angular ridge extends ventrally 
from the beak, in this cast, but disappears at a point slightly more 
than half way from the beak to the ventral margin. Anterior to 
the beak, a small but deep lunule has been carved out, and posterior 
to the beak a high hinge area is seen. It is evident that the greater 
part of the posterior portion of the shell is absent, but traces of con- 
centric striae suggest that the shell was comparatively short. 
There is a possibility of Angellum cuneatum being related to 
Bodmania insuetum, a species also described from the Whitewater 
at Richmond, Indiana, (1894, Miller and Faber, Jour. Cincinnati 
Soc. Nat. Hist., 17, p. 23, pi. 1, figs. 5-7), apparently another Cyrto- 
dontoid form, but the latter appears to have had more prominent 
and inflated beaks, giving it a much more broadly rhombic-cordate 
outline when viewed from the front. The attempted restoration 
of the posterior parts of this type, as shown by figure 3fc on plate 
VII, may be regarded as a wild guess. Q
