Doydixodon. Messrs. Kner & Steindachner have received 
from the Godelfroy Museum an example from Iquique on the 
west coast of South America, which they describe as a new spe- 
cies, D. fasciatum, Sitzgsber. Ak. Wiss. Wien, liv. p. 358, fig. 2. 
The authors state that Gunther erroneously describes the vomer 
as toothless, and the praeoperculum as entire. Valenciennes^s 
original account in the ^ Voyage of the Venus ^ was not accessible 
to them. — [If the authors had been accurate in their statements, 
they would have added that I had no specimen for examination 
when I formed the diagnosis of Doydixodon, and, consequently, 
that the reproach of incorrectness should have been made to 
Valenciennes, who gave the original description of this fish. 
However, I was on the point of adopting the correction made by 
the Viennese ichthyologists, when I fortunately received from 
the GodefFroy Museum one of the typical specimens of this D, 
fasciatum, and, on examining it I found that, in this case, Valen- 
ciennes was the correct observer. The specimen is of the same 
size as that sent to Vienna. It has no trace of vomerine teeth, 
the entire palate being covered by a soft papillose mucous mem- 
brane ; and, likewise, the praeoperculum is without any indication 
of serrature. The dorsal fin P|, anal are as stated by Messrs. 
Kner and Steindachner. The same numbers are represented in 
Valenciennes's figure, so that those given by him in the text ap- 
pear to be incorrect. The faint cross bands observed by Messrs. 
K. & St. have disappeared, and the specimen is now uniform
