140 THE NAUTILUS. 



of specimens of the variety I call Utahensis. (See p. 33. ) This 

 has the form of HemphillL but is destitute of the revolving ridges 

 of Haydeni. The specimens were all constant in sculpturing, 

 but varied very much in size and somewhat in form." 



According to labels sent out with specimens at the time, Mr. 

 Hemphill considered utahensis to be a variety of hemphilli Nc., 

 but this does not appear in the printed account. 



On page 33 of the same work (Second Supplement to Vol. V, 

 T. M. ), Binney gives the following account : 



" Var. UTAHENSIS, Hemphill. 



" For locality, see ante p. 30. This is a rough, coarse, cari- 

 nated strigosa, figured in Terr. Moll., V, p. 158, fig. 66. The 

 peristome is sometimes continuous by a heavy raised callus, 

 connecting its terminations. It is sometimes smaller and more 

 elevated." 



It appears from both of these extracts that the type locality of 

 var. utahensis is the Oquirrh Mountains, in Utah, west of Salt 

 Lake City. The diagnosis of the form given in Hemphill' s 

 letter leaves much to be desired. Even with the type locality, 

 the form could hardly be recognized with certainty without 

 specimens from the author. Yet in the absence of any com- 

 peting name for the same form, we may accept Hemphill's 

 notes as a description, since they are accurate as far as they go. 



Binney, while reiterating Hemphill's locality, introduced con- 

 fusion by referring to fig. 66 of Terr. Moll. V (same cut was 

 reprinted as fig. 154, in Man. Amer. Land Shells), and adding 

 characters from the shell that cut represents. This fig. 66 was 

 originally published in Land and Fresh- Water Shells of N. A., 

 part I, p. 78, figs. 135, 137, with the note, "It is sometimes 

 strongly carinated, and the peristome is sometimes made con- 

 tinuous by the heavy, raised callus connecting its extremities." 

 At this time (1869) no shells Avere known from the Oquirrh 

 Mountains. The figures in question were drawn from a shell 

 from the Big Horn Mts., in northern central Wyoming, collected 

 by the geologist F. V. Hayden. This shell was collected in 

 quantity, and there are specimens from the same source (and 

 also received through Binney) in the collections of the Academy 

 of Natural Sciences, the National Museum, and the American
