506 GEOLOGICAL SURVEY OF THE TERRITORIES. 



If found in any of tlie Pal;i?ozoio rocks, most geologists would refer it 

 to Loxonema of Pliillips. Whether or not the nucleus or apex of its 

 spire was covered as in the typical species of TurboniUa I liave been 

 unable to determine. It is a far larger shell, however, than the species 

 upon which that genus was founded. 



Specifically, this shell seems to be related to TurboniUa SpiJlmani, 

 Conrad. (Jour. Acad. N. S., vol. iv, new series, PI. 40, Fig. L*8,) but its 

 vertical folds or costtc are straighter, less crowded, and less numerous, 

 while its revolving lines are smaller and more numerous. Its aperture 

 also certainly (Utfers in being decidedly more angular above, and proba- 

 bly somewhat so below. It may likewise be compared with tScaluria 

 Mathewsonii., Gabb, from Cretaceous rocks of Calilbrnia, from which it 

 dilfers in having less convex volutions, or less rounded ai)erture, less 

 crowded verti(;al ridges, and more distinct and coarse revolving lines. 



Locality and position. — Coalville, Utah ; from below the lowest heavy 

 bed of coal at that locality. Cretaceous. 



EuLiMA FUNICULA, Meek. 



Shell subterete or elongate-conical; spire regularly tapering from 

 the middle of the body volution to the apex, or with very slightly convex 

 slopes; volutions about twelve, flattened ; last turn not much enlarged, 

 subangular around the middle ; suture merely linear ; aperture ovate or 

 rhombic-subovate ; inner lip slightly thickened and reflected. Surface 

 smooth. 



Length, 0.65 inch ; breadth, 0.20 inch ; divergence of slopes of spire, 

 about llP. 



This shell has much the appearance of a slender Niso, hut it certainly 

 wants the undiilicus seen in that genus; its axis not being in the 

 slightest degree perforated. It is even more like some recent species of 

 IJulimt'lUi, and may possibly have to take the name EnUmcUa funicula 

 when its generic characters can be more clearly determined from the ex- 

 amination of good specimens. The best exami)les 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 columella 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. 



EuLrMA"? criKYSALLis, Meek. 



Shell small, elongatesubconoid, or subfusiform ; spire conical; vo- 

 lutions about eight, flattened nearly to the slope of the spire; suture 

 nearly linear ; aperture subovate ; inner lip a little reflected and mod- 

 erately arched ; outer lii) urdniown ; surface smooth. 



Length about 0.29 inch ; breadth, 0.12 inch. 



I ani by no means sure this is a true EuUma., not having seen any 

 specimens showing very clearly the form of the aperture, or the nature 

 of the outer lii». It has the general aspect of that genus, however, and 

 may be placed there provisionally for the i)resent, until better speci- 

 mens can be obtained for study. It will be at once distinguished 

 from the last, by its less produced spire, less numerous volutions, and 

 proportionally larger body-whorl. 



Locality and position. — Carleton's coal-mine, near Coalville, Utah. 

 Cretaceous.
