Edmondia ovata; pl. XXv1, fig. 13.—At the time the figure 
of this shell and the explanations of the plate were prepared at 
Springfield, being in doubt in regard to its relations to one of 
the Nebraska species, of which there were no specimens or other 
means of comparison at hand, I merely wrote with a pencil, 
provisionally, opposite its number on the explanations of the 
ate, the name Hdmondia ovata, which was also in the same 
way attached to the specimens. The intention was, at the 
time, to make thorough comparjsons with the Nebraska shell 
in preparing the text for the press. As this intended revision 
and preparation of the text was prevented by sickness, how- 
ever, the merely provisional name was, as in some other cases, 
printed as originally written. 
Since the publication of the report, I find, on comparison, 
that this shell is so nearly like the Nebraska form I have 
called #. subtruncata (Paleont. E. Nebr., p. 215, pl. u,, fig. 7), 
that it may be only a variety of the same. It is proportionally 
a little longer, and has its beaks somewhat more distant from 
the anterior end, which is rather more broadly rounded in out- 
line. It may be a distinct species, but I should have hesitated 
to name it as such, had I been able to make the comparisons 
entertained in regard to their identity, at least, with the Ne- 
braska specimens. In the
