It is evident from the foregoing discussion that the Council Bluff of Say’s 
and Nicollet’s reports, and all others based upon them, is a Nebraska locality, 
and this is also true of the “Engineer Cantonment,” or “Cantonment.” Where 
reference is made to “Bowyer’s Creek,” “Boyers River,” or Boyer river, the 
locality is on the Iowa side. It is not probable that Say made many excursions 
to the Iowa side of the Missouri river, the broad prairie bottom-lands of that 
side being less inviting than the wooded bluffs of the Nebraska side, and the 
difficulty of crossing the Missouri probably adding an obstacle. His journal, 
copied by James, shows that he did occasionally cross to the Iowa side, and a 
longer trip was taken along the Boyer to the present site of Logan, Iowa.* 
It may seem that the exact location of Council Bluff is not a matter of 
serious moment, but this locality is cited in many scientific papers and is 
therefore of interest to students of plant and animal distribution. In addition 
to the general desirability of accuracy there are two reasons for correcting 
the impression that the Council Bluff of the earlier reports is Council Bluffs, 
Iowa. The two localities are on opposite sides of the Missouri river, and 
hence in different states, and the difference of about 27 miles between them 
is sufficiently great to be of interest in connection with the preparation of 
state lists. Say invariably wrote the name Council Bluff, and most of the 
authors who subsequently copied his record used the same form. But in some 
cases, particularly those of more recent date, an effort was made to supply the 
name of the state or territory, and an error has resulted. Thus Frank C. 
Baker, in a recent work,** cites “Council Bluffs, Iowa,” as the type locality for 
Lymnaea umhrosa Say, a form of Galda elodes (p. 324), and among the locali- 
ties for Qalha elodes appears the following: 'Gown: Missouri River, in the 
vicinity of Council Bluffs, Pottawattamie county (Say).” Say’s original record 
mentions neither county nor state. The only accurate reference of Council 
Bluff to Nebraska which the writer has seen in locality citations of this 
kind appears in W. G. Binney’s report on Land Shells.
