Zonites minusculus, Binvey. 
Universally distributed. . 
Zonites milium, Morssr. 
Not actually received from the Central Province, but no doubt existing there, 
as it has been found over the Eastern and Californian Provinces. Probably a 
universally distributed species. 
Zonites fulvus, Drar. 
A universally distributed species, received from numerous localities in Utah, 
Nevada, and Colorado. 
Vitrina Pfeifferi, Newc. 
A species of the California Province. I have received it also from Logan 
Cafion, Weber Cafion, St. George, and Salt Lake City, Utah; Austin and 
White Pine, Nevada: White Bird Creek, Idaho. (Hemphill.) 
Patula solitaria, Say. 
Plate I. Fig. 10. 
A species of the interior region of the Eastern Province. I have received 
it also from White Bird Creek, Idaho; Walla Walla, Washington Territory ; 
Weston, Oregon (Hemphill); in addition to the localities given in Vol. V. 
These last two points are about twenty-five miles apart, at the foot of the Blue 
Mountains, one hundred and fifty miles from the Dalles. 
The specimen figured, which is unusually elevated, is from Salmon River 
Mountains, Idaho (Hemphill). A uniformly brown specimen with narrow 
white band was also found. 
One of the most unlooked for and interesting facts in the geographical distri- 
bution of our land shells is the westward range of P. solitaria, reaching through 
the Central Province into the Pacific Province to within a few miles of the 
Pacific Ocean. (See extracts from Mr. Hemphill’s letter on pp. 27, 28.) 
Patula strigosa, GouLp. 
Plate II. 
This is the most variable species found in North America. The original 
specimen (see Pl. XX VI. a), found on or near the Pacific Coast at Puget Sound 
by the naturalists of the Wilkes Exploring Expedition, is large, almost discoidal, 
with widely open umbilicus. It could not possibly occur to me that there were 
any relations between it and the small, globose, narrowly umbilicated, highly
