PREFACE. 



arcuata, Horsf. has been before placed by Mr. Swainson, and on which species he instituted the 



genus; the musk duck ( Carina moschata, Flein.) is placed in the same genus with the common 

 sheldrake (Tadorna) ; the blue-winged teal ( Anas discors, Linn. Cyanopterus discors nobis), the 

 Baikal teal (Anas fonnosa, Linn. Querquedula formosa nobis), and the Java teal (Anas Java- 

 nensis, Lath. Querquedula Javanensis nobis), are all placed in Genus Boschas, Sir. together 

 with the common wild duck. The specific name also of Javanensis is altered to Javanica. 



We have also, since the printing of our generic characters, seen an article in the " Penny 

 Cyclopaedia" (Fuliffulince) relating to a portion of the Anatidce, in which we are informed that the 

 generic appellation of Chauliodus has been pre-occupied : as we find on reference this to have been 

 the case, we venture to propose that of Ktinorhynchus instead, alluding to the comb-like appearance 

 of the lamella? on each side of the bill. 



In the Catalogue of European and American Birds, just published by the Prince of Musignano, 

 the generic name Ckauliodes is altered to Chanlelasmus, Gray, which had priority to our name for 

 the same genus, having been published first; and Fuliyula Americana, Bonap. is altered to 

 Aythya Erythrocephala, Bonap. which genus we do not think a good one ; its true name, there- 

 fore, will be Fuligula Erytltrocephala. 



Brehm's work " Hanbuck der Naturgeschite aller vogel Deutschlands" would have been 

 scarcely worthy of notice, had it not been that some new r genera had been instituted in it, and also 

 the synonyms of Boie, wdiich are valuable, as they forestall many of those given by authors in this 

 country. Looking at the work, however, altogether, it is worse than those of the older authors as 

 regards the creation of false species, five or six species in many instances being made of one.
