FUL1GULINJE.] 



GO 



We first instituted this genus on F. rufina, after having observed the trachea of that species. 

 To this, however, will be added the beautiful species Fuligula caryophylacea. With any 

 anatomical character further than that above given we are unacquainted, not having ever seen the 

 skeleton. 



Affinities. In having bulbs on the tube of the trachea, and also in general form, this bird 

 presents considerable affinity to the Mergansers.
