THE NAUTILUS. 67 



practically equivalent to the old Teuthis Schneider 1784, not 

 of Linngeus 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. 



NOTIS ON A SMALL COLLECTION OF 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."
