mella, and may possibly have to take the name Eulimella funicnla, 

 when its generic characters can be more clearly determined from the 

 examination of good specimens. The best examples I have seen do not 

 show the extreme apex of the spire, or very clearly the form of the 

 aperture. So far as can be determined, however, its columnella does 

 not seem to present the straightness seen in Eulimella, I know of no 

 closely allied Cretaceous species. 



" Locality and position. — Cretaceous at Coalville, Utah." 

 Some specimens from the north fork of Virgin river were described 

 by Dr. C. A. White, who afterward added the following note on the 

 species : 



"The examples described and illustrated by me (loc. cit.) were pub- 

 lished before I had seen either Mr. Meek's types or his drawings, having 

 access only to his published descriptions. Subsequently comparison 

 raises a doubt as to their specific identity, but they are evidently con- 

 generic. My examples were more robust than Mr. Meek's, with a 

 wider apical angle. It is possible that neither of these forms should 

 be referred to Eulimella^ but they certainly agree more nearly with the 

 characteristics of that genus than with any other, so far as they are 

 yet known."

Original description: 



" Shell elongate-conical; volutions ten or eleven, moderately convex; 

 last one not much produced below, rounded, or sometimes obscurely sub- 

 angular around the middle; suture well defined; aperture rhombic- 

 suboval, being angular above and apparently a little so below; inner 

 lip slightly thickened, rather deeply arched, a little reflected, and closely 

 appressed below ; outer lip thin . Surface ornamented by rather strong, 

 simple, regular, nearly or quite straight vertical ridges, crossed by reg- 

 ularly disposed revolving lines (about ten or eleven of the ridges and 

 five or six of the revolving lines being seen on each volution of the 

 spire), while only the revolving lines are continued below the middle 

 of the body volution. 



" Length of a large specimen, 1 inch; breadth, 0.40 inch; angle of 

 spire, from 20° to 25°. 



" None of the specimens of this species yet seen are quite perfectly 

 preserved at the base of the aperture. Some of them look as if there 

 had been a slight angularity there, while others, differing in no other 

 respect, present appearances that leave room for doubt on this point. 

 In some of its characters this shell reminds one of the fresh- water Go-
