to prevent'the propagation of many errors which are observable 
throughout the pages before me, but also to enter my feeble pro- 
test against the efforts of any individual to stand on ground which 
is already occupied—to redescribe, under new generic and spe- 
cific names, genera and species which have been known and 
acknowledged by scientific men. 
Previous to presenting you these rough notes, I would sinaiai 
I have endeavored to persuade another, possessing more leisure 
and much more accurate knowledge of many of the fluviatile

save such as should actuate every naturalist, I shall be most happy, 
if I have unintentionally wronged him, to do him full justice—

There is undoubtedly much valuable fnfortnation in the volume 
before us; prepared as it is by one who ina manner represents 
the zoologists of the state of New York, it cannot be otherwise. 
It is not my purpose to dwell upon its merits ; they will undoubt-

point out to you some of its defects. And as I have been ena-
