THE NAUTILUS. 67 
practically equivalent to the old Teuthis Schneider 1784, not 
of Linnzus 1766, which is a genus of fishes. 
It has recently been called to my attention that Acroteuthis 
in this sense is itself invalid by reason of the existence of a 
prior usage of the same name in connection with a fossil 
genus of the same group of mollusks, a fact which had escaped 
my notice because of an almost complete lack from my library 
of the literature of cephalopod paleontology. 
To remedy this unfortunate situation, I would suggest that 
the name Acruroteuthis be adopted as a substitute for Acro- 
teuthis Berry 1913. 
NOTES ON A SMALL COLLECTION UF SHELLS FROM ALASKA.* 
BY FRANK C. BAKER. 
A small collection of Alaska mollusks has recently been given 
to the Museum of Natural History which is of considerable in- 
terest. It was collected by Dr. Henry B. Ward, head of the 
Department of Zoology, University of Illinois, while engaged in 
survey work for the United States Bureau of Fisheries. The 
shells were collected incidentally during the months of July and 
August. The two bodies of water from which the material was 
collected are in the Copper River drainage and their location is 
thus described by Dr. Ward: 
‘*The two lakes referred to as the locations from which the 
mollusks came are both in the drainage of the Copper River. 
Long Lake lies just off the Chitina River, which is the main 
tributary of the Copper River. The lake is right alongside the 
Copper River and the Northwestern Railway track, and is some- 
thing like 150 miles from Cordova. 
‘‘Saint Anne Lake empties into Lake Klutina, which in turn 
empties through the Klutina River into the Copper River. This 
is on the west side of the drainage basin, about 250 miles from 
‘the Long Lake locality.”’
