and whose little, black, 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- 

 able forms. Eburna japonica and a large Cardium seemed the most 

 favored as articles of diet. 



ANNOTATED LIST OF THE MOLLTTSCA 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- 

 siderata; 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 Clear/water 

 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 Archaean 

 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 hanks, with 

 an occasional muddy slough connected.
