and whose little, biack, oblique eyes could almost see around corners, 
The market places usually offer a number of the more common 
‘species, among which one can often pick out rarer and more desir-

favored as articles of diet. 
ANNOTATED LIST OF THE MOLLUSCA FOUND IN THE VICINITY OF 
CLEARWATER, WRIGHT CO., MINNESOTA. 
BY H. E. SARGENT, WOODVILLE, ALA. 
PART FIRST—LAND SHELLS. 
Having the past summer at our disposal, and needing rest, our 
plans were laid gastronomically to enjoy the fruits of the old home- 
stead garden, the pride of our octogenarian parent ; socially, to re- 
new the acquaintance of relatives and friends of former years, and, 
scientifically, for our own gratification and perhaps that of our 
fellow conchologists, to work up as fully as possible the molluscan 
fauna of the immediate vicinity of our sojourn. The two first de- 
sideratee of the vacation were a pre-eminent success, and our friends 
may be our judges as to the latter. 
Clearwater, Wright Co., Minnesota, is situated on the Clearwater 
River, at its junction with the Mississippi, some 60 miles above the 
famous Falls of St. Anthony. 
The Mississippi, at this point is, at times, deep, rapid and filled 
with loose logs for the Minneapolis saw-mills. At the time of our 
investigations it was shallow, quiet and free from logs, thus greatly 
aiding in our search. Its bed being in the glacial drift, contains but 
little, if any, lime-rock. 
Fine granite is quarried from the outcropping of the Archean 
rocks at St. Cloud, only 15 miles above. 
The several islands which occur at this point are low and densely 
overgrown with willows, elms, vines and rank weeds. 
Being protected from fires, the undergrowth is a perfect tangle of 
‘dead limbs and living weeds. The portions which are overflowed in 
high water are cleared and more open. 
The Clearwater River, a small stream easily crossed dry shod in 
summer, is from 8-10 miles long, and the outlet of Clearwater Lake, 
Except in the most rapid portions, it is muddy under its banks, with 
an occasional muddy slough connected.
