places, and at no point is it shallow. The width, on the other 
hand, is but a few hundred yards except at Wiscasset, where it is 
three quarters of a mile wide. The river is famous for its scallops, 
Pecten magellanicus Gmelin, these occur for the most part in the 
lower part of the river. 
It was frequently reported to me that oysters were to be found 
“up river” four or five miles. I am sorry to say I had but one day 
“up river;” that trip, however, revealed the fact that a very nar- 
row spot known as the Falls, separated an upper basin from the 
main part of the river. Here in the warmer waters oysters do 
occur, but very few and far between. With the oysters I found a 
few of the old companions noticed in Northumberland Straits, and 
abounding south of Cape Cod. 
As a whole this river is rich in specimens, and the cold and warm 
water species are by no means distant neighbors. Some forms are 
dwarfed, some like Bullinella alba, are colored probably by 
iron to a darker shade than the normal. I believe that more spe- 
cies may be added to the list by a more careful search above the 
place dredged. I give the list of those found by me in the area 
extending four or five miles each way from Wiscassett.
