32 BULLETIN OF THE 



Var. Newcombi, HEMPHILL. 



Plate II. Fig. 8. 



Near Ogden, Utah (H. Hemphill). (See ante, p. 30.) 



This variety has numerous separated, rough, heavy, transverse ribs (forty- 

 four on the first whorl of one individual), and two widely separated, revolving 

 bands of color. It varies, as usual in the group, in size and globoseness. Some 

 want the revolving band. 



Var. multicostata, HEMPHILL. 

 Plate II. Fig. 6. 



Box Elder County, Utah (H. Hemphill). 



On one specimen I counted over seventy coarse rib-like striae to the first 

 whorl. There are two revolving bands of chestnut on all the individuals re- 

 ceived from Mr. Hemphill. Two have the denticle on the peristorne. 



Var. Gouldi, HEMPHILL. 

 Plate II. Figs. 5, 16. 



Banks of Bear River, north of Brigham City, Utah (H. Hemphill). (See p. 31.) 

 One individual has sixty-two rough wrinkles on the first whorl. There are 

 two revolving bands of color. The specimen figured (Fig. 16) is the largest sent 

 me by Mr. Hemphill, others being smaller by one half, and some being very 

 much depressed (Fig. 5). Among the thousand specimens collected, none were 

 large. 



Var. albofasciata, HEMPHILL. 



Plate II. Figs. 3, 4. 



Same vicinity as the last. (See p. 31.) 



The body of the whorl is clouded, with a broad, revolving white band at the 

 periphery, and white around the umbilicus. Some individuals are white with 

 two revolving bands of color. On one there are about seventy rough wrinkles 

 to the first whorl. Some have a toothlike process on the peristome (Fig. 4). 

 The variety differs, as usual in the group, in the elevation of the spire and in 

 size.

 subsequent visit.
