286 SMITHSONIAN MISCELI.ANEOUS COLLECTIONS VOL. 52 



sets of this periodical in the Library of Congress and the National 

 Museum are incomplete, the idea can not here be verified or dis- 

 proved. A supplementary account may be given later. As Zolot- 

 nitsky, who must have been acquainted with the two articles, made 

 no comments on them, none are called for here. It is to be hoped 

 that some American institution (the New York Aquarium, for in- 

 stance) may be sufficiently enterprising to import some fishes and 

 enable us to confirm or correct the published observations.
