hilli has the last embryonic whorl a trifle concave near the periphery, 

 where yours is only flattened, but the difference is not great. 0. 

 carinifera has the embryonic whorls well rounded throughout, above; 

 it is more depressed and the keel is decidedly pinched out on the last 

 whorl. It may turn out to be another subspecies of hemphilli, 

 but with present collections I hardly think so. I do not know what 

 form Binney identified as hemphilli from Colorado. My comparisons 

 were with the figured type and a young one of the original lot. " 



The Oquirrh Mountains. 



This range extends southward from the southern end of Great 

 Salt Lake. Hemphill visited the west side of the range, 5 and reported 

 a very interesting series of finds, with 0. utahensis at the foot of the 

 mountains, 0. oquirrhensis a short distance up the mountain side, 

 then along the mountain side across a ravine the typical haydeni and 

 gabbiana, and near the summit a few haydeni and two cooperi. We 

 searched the canyons around Tooele without finding any of these 

 forms. Then we proceeded to Garfield and worked southward along 

 the west side of the range for many miles and only found one species, 

 at stations 14 and 15. Material labelled haydeni in Clapp's Hemphill 

 collection does not appear to belong to that species. 



Station 11, cottonwood grove at picnic grounds just within mouth 

 of gulch southeast of Tooele from which gulch the town obtains its 

 water supply. 



Paludesirina longinqua (Gould), abundant in water-cress. 



Pyramidula cronkhitei anthonyi Pils.. 14 specimens. 



Euconulus sp., 1 juvenile. 



Vitrina alaskana Dall, 2 dead shells. 



Zonitoides arborea Say, 3 specimens. 



Pupilla blandi Morse, 1 specimen. 



Station 12, up the canyon a short distance above Station 11, in 

 rock slide, mostly quartzitic sandstone. 



Vitrina alaskana Dall, 3 specimens. 



Pyramidula cronkhitei anthonyi Pils., 3 specimens. 



Vitrea indentata umbilicata (Ckll.), 12 specimens. 



Oreohelix strigosa depressa (Ckll.) common. 



Oreohelix strigosa depressa (Ckll.). 



Sta. 12 (see above) ; Sta. 13, about a mile above Sta. 12, on south 

 side, under mountain maple leaves. These two lots are typical in 



6 Binney's 2nd Suppl. to 5th Vol. Terr. Moll. U. S., pp. 29-34.
