76 PROCEEDINGS OF THE ACADEMY OF [Feb., 



marked or uniform. Valvata h. californica here is less highly polished 

 and more loosely coiled than at Sta. 78, Bear Lake. 



Sta. 125, creek and sloughs south of Provo, from one to two miles 

 north of Springville. 



Succinea haydeni W. G. B. Lymncea humilis modicel a Say. 



Paludestrina longinqua (Gld.). Planorbis trivolvis near hinneyi 

 Fluminicola fusca (Hald.). Tryon. 



Valvata humeralis californica Pils. Planorbis ^parvus Say. 



Lymncea proxima Lea. Physa crandalli Baker ? 

 Lymncea stagnalis appressa Say. 



The Planorbis cf. hinneyi here is much smaller than at Sta. 127, 

 the largest measuring only 20.5 mm. in diameter; some as strongly 

 sculptured, but the whorls not so strap-like; some with the nearly 

 circular aperture of horfiii Tryon. Yarrow^^ records Physa eUiptica 

 Lea from Provo, Rush Lake and Virgin River, Utah. To what 

 species his records should be referred we do not know.* CrandalP*^ 

 confines P. eUiptica to the region east of the Mississippi. 



Sta. 126, gulch a mile and a half northeast of Springville. Oreohelix 

 strigosa depressa (Ckll.), a few dead shells found, no live examples 

 obtained. 



Oquirrh Mountains, Utah. 



We spent one rainy day at Bingham. Such investigation as we 

 were able to make in the rain led to the conclusion that it is not good 

 snail territory, though doubtless more extensive and persistent search 

 would result in some finds. 



Sta. 116, rock slides and ledges, chiefly limestone, south and 

 southeast of Garfield, on the ancient lake terraces at the northern end 

 of the range. Oreohelix cooperi (W. G. B.) (?), plentiful in rock slides, 

 but several hours of digging deep into the slides and under the new 

 growth of shrubs failed to produce a single live snail. The dead 

 shells were weathered and scorched, the periostracum and embryonic 

 sculpture destroyed, so we do not feel confident of their identity. 



Sta. 117, gravel pit on one of the lake terraces north of the west 

 edge of Garfield. This pit yielded fossil fresh-water shells of species 

 living now in the region, and added nothing to the fossils recorded 

 from the region by Call. 



Sta. 118, sloughs between the west end of Garfield and the main 

 line of the railroad.
