any specimen showing very clearly the form of the aperture or the 
nature of the outer lip. It has the general aspect of that genus, how- 
ever, and:may be placed there provisionally for the present until better 
specimens can be obtained for study. It will be at once distinguished 
from the last* by a less produced spire, less numerous volutions, and 
proportionally larger body-whorl.

Among a considerable number of examples of the Hulima? funicula 
of Meek, which have been collected from the marine Cretaceous strata 
both at Coalville and at the North Fork of Virgin River, Utah, are 
some which indicate a nearer relation to Hulimella than to Hulima. I 
have, consequently, in other writings,t referred that species provision- 
ally to the former rather than to the latter genus. The two species 
from the estuary beds at Coalville, described and figured in this article, 
seem to be congeneric with H. funicula, and I therefore refer these 
also to Hulimella, with similar doubt. 
EULIMELLA? INCONSPICUA Meek.

_ “Shell small, conoid-subovate ; spire conical; volutions eight or nine, 
a little convex, compactly coiled; suture distinct; aperture apparently 
- subovate; surface smooth. 
“Length 0.17 inch; breadth 0.07 inch; spire with straight slope 
that diverges at an angle of about 22°. 
“This is another form that I only refer with great doubt to Hulima, 
the specimen not being in a condition to show the exact form and nature 
of the aperture. It will be readily distinguished from the last by its 
- more convex volutions, proportionally shorter spire, and more expanded 
body-whorl. It is probably not a Hulima.

This also is one of the species embraced in the estuary fauna of the 
Cretaceous strata at Coalville, the only known examples of which were 
discovered by Mr. Meek. It seems to be a true Valvata, and as such its 
discovery adds another fact to those already known concerning the 
early differentiation of certain molluscan types which characterize more 
recent fossil, as well as existing, fresh-water faunz. The following is Mr. 
Meek’s description : 
“Shell small, depressed stibglobose, or subdiscoidal; spire depressed ; 
volutions three and a half, rounded, suture deep; umbilicus compara-
