It is probable that the Sphcerium and the Fluminicola may be 

 found in favorable situations all along the stream, and the former 

 was noted as a fossil in the alluvial banks of the river at several 

 places. 



Sta. 2, south side of Harkness Canyon, at the springs near a great 

 white cliff plainly visible from McCammon. The large, heavy- 

 shelled Oreohelix strigosa depressa (Ckll.), noted for this station in 

 our former report, occurs in limestone slides on a steep slope almost 

 concealed by a heavy cover of conifers, with an undergrowth of 

 mountain maples and various shrubs. A conifer forest is^ an unusual 

 habitat for such a fine colony of Oreohelix. In the bottomland 

 below the slides ' we found dead shells of Thysanophora ingersolli 

 (Bland) plentiful in fine drift wood, and a short distance down the 

 canyon we obtained Euconulus fulvus alaskensis Pils., Zonitoides 

 •arhorea (Say), Vitrina alaskana Dall and Vallonia cydopliorella Ancey. 



Sta. 65, east side of gulch coming into Harkness Canyon from the 

 north, above Sta. 2. Large Oreohelix strigosa depressa (Ckll.) 

 abundant, in more open, cleaner slides than at Sta. 2, with few trees 

 and much less shrubbery and herbage. 



Sta. 66, Goodenough Canyon, on east side of a mountain range 

 about five miles west of McCammon. We drove to the end of the 

 road up the canyon, then walked a mile further. Found no lime- 

 stone, no good rock slides and no Oreohelix, but under leaves and 

 sticks we obtained the following : 



Zonitoides arhorea (Say). Euconulus fulvus alaskensis Pils. 



Pyramidula cronkhitei anthonyi Punctum n. sp. 



Pils. Vertigo modesta parietalis 



Vitrina alaskana Dall. (Ancey). 

 Thysanophora ingersolli (Bland) . 



Bear Lake Valley Idaho and Utah. 



Bear Lake, at an altitude of 5,925 feet, is about nineteen miles 

 long (north to south) and from six to eight miles in width, bisected 

 by the Utah-Idaho boundary line. It is bounded on the east, west 

 and south by mountains, but the broad valley extends to the north- 

 ward beyond Montpelier to Bennington, thus giving the valley a 

 length of forty miles, drained by the Bear River, which flows into 

 Great Salt Lake. In the Geologic Atlas of the United States (United 

 States Geo'-Ogical Survey) the region is covered by the Montpelier 

 (Idaho) and Randolph (Utah) Quadrangle sheets. We did not visit 

 the eastern or southern shores of the lake, but spent half a day at
