ERRATA. 
(For Serial Numbers of Utterback on The Naiades of Missouri, Vol. IV.) 
Some errors have been due partly to improper and insufficient correc- 
tions of the MS. which originally followed Lindahl’s ‘‘Orthography of the 
Names of Natades,’’—an article that adheres strictly to the International 
Code. Most of the other errors are the typographical mistakes that usually 
escape even the most careful proof-reading.
