Stations 47 and 49 to 56 are all on the north side of the canyon, 

 while stations 48 and 110 to 115 are on the south side. 



Salt Lake City, Utah. 



We did not stop at Salt Lake City to do any collecting in 1916, 

 but have recently received from Mr. L. A. Giddings, of that city, 

 two small lots of Oreohelix strigosa depressa form carnea (Hemph.), 

 one from his Sta. 1, upper slopes of Red Butte Canyon, the other 

 from his Sta. 2, close to the creek in City Creek Canyon. In both 

 lots the spires are much more elevated than usual, but otherwise they 

 correspond with Hemphill's specimens of carnea, of which the type 

 locality is "near Salt Lake, Utah," and which we found in Dry 

 Canyon in 1915. Pilsbry writes that the anatomy is that of depressa. 

 It may be well to say that this form, sent out by Hemphill, is to be 

 found in many cabinets bearing a printed label on which, l)y a 

 typographical error, an o has taken the place of an a, making the name 

 corneus, which should be corrected. We also note another typo- 

 graphical error in Hemphill's printed labels, the i having been omitted 

 from gabbiana. 



CalP^ reported the following species from this locality:

Anodonta nidtalliana Lea. Planorbis trivolvis Say. 



Valvata sincera {^&y). Physa gyrina elliptica Lesi. 



As he placed A. wahlametensis Lea and A. californiensis Lea in the 

 synonymy of A. nutialliana Lea, which of these forms he found 

 "somewhat common in the fresh-water streams near Salt Lake City" 

 is an open question. His L. stagnalis is either appressd or wasatchen- 

 sis. Baker^^ reports L. s. wasatchensis and L. proxima Lea from near 

 Salt Lake City. Yarrow-^ reports L. stagnalis and Valvata sincera 

 from "near Salt Lake City." IngersoU-^ also records V. sincera 

 from here. Probably all these records of V. sincera should be referred
