The specimen was procured by Mr. Townsend 
on the Columbia river. 
I am obliged to confess that I should not have 
ventured to publish this species as distinct from the 
preceding, on my own responsibility. The discri- 
minating eye of Dr. Richardson, however, who has 
studied this genus more carefully than I have had 
an opportunity of doing, may have detected marks 
of difference which I have not been able to discover. 
As the species, however, will be given under the 
above name, I have found it necessary to indicate 
it here.
