THE NAUTILUS. iM fae 
The next day we left the main river and followed a slough that led 
us into three large lakes that run to the foot of the mountains. The 
banks are ten to twenty feet high and perpendicular. Near the water 
was a stratum of shells (Macoma inconspicua Brod.), about four inches 
thick. This locality is about 100 miles from the Aphroon mouth of’ the 
Yukon. 
Atan Indian camp below Holy Cross Mission I saw the right valve 
of an Anodonta used as a spoon by an old squaw. She could not under- 
stand, or would not, so I could not learn where it was found. She also 
prized it so highly that, though offered a good trade, she would not. 
part with it. It was the size and color of our Anodonta oregonensis. 
We made an early camp at Point Romanoff, which is about half way 
from the mouth of the river to St. Michael’s,on the Arctic Ocean. 
Here I had to make use of the same expedient that I used before to: 
“stand off”’ the mosquitves, and found on the drift wood on the beach 
specimens of Conulus fudvus alaskensis Pils. and Pupa decora Gould. 
After entering the canal that connects the Arctic Ocean with Norton’s 
Sound I found the small ponds that are common on the trundra full of 
Limnexa palustris Miull., most of them of large size. I also found a 
small bivalve very plentiful that was new to me, and I collected a 
large number of them ; but, alas! they belong to the Crustaceans and 
the other fellows are enjoying them. 
I did not find any marine shells at St Michael’s, but when we stopped 
at Unalaska, on the Aleutian Islands, I had a low tide to work on, and 
on the rock spit near the dock collected and recognized the following 
species: 
Purpura lima Mart: 
Buccinum fischerianum Morch. 
Volutharpa ampullacea Midd. 
Margarita helicina Fabr. 
Margarita albula Gould. 
Littorina sitchana Phil. 
Tritonium oregonense Redf. 
Kulima sp. 
Acmzxa patina Esch. 
Pecten sp., dead shell. 
Sazicava ruaosa I. 
Saxidomus squalidus, 
Modiola modiolus Lam. 
Mytilus edulis 1.
