In our paper on Mr. Whitely’s birds read before this Society on 
the 11th of March last, we have referred this bird to the species 
described by Tschudi as Merganetta leucogenys. Having, however, 
more recently made a re-investigation of the group, we have con- 
vinced ourselves that Tschudi’s bird is, so far as can be decided by 
his figure and description, inseparable from the Merganetta colum- 
biana of New Granada, and that the present species must be regarded 
as undescribed, being equally distinct from the New-Granadan 
form, and from the Chilian Merganetta armata. From the former 
it differs in its larger size, and black breast and flanks, which 
are only relieved by some brownish marks in the middle of the belly. 
In the New-Granadan bird, which is well represented in Des Murs’s 
‘Iconographie’ (tab. vi.), the whole abdomen is white, sparingly 
striped with narrow blackish markings, and the bill is narrower 
and much less elevated than in this species. Merganetta armata, 
of which an excellent figure will be found in Gray and Mitchell’s 
‘Genera of Birds,’ resembles the present bird in having a black 
breast ; but the edges of the scapularies are white instead of rufous, 
and the throat and fore neck are black, instead of being pure 
white as in its two northern allies. It would seem, therefore, that 
our new species occupies an intermediate position as regards the 
differential characters of the male, just as it does in geographical 
range, between the two known species. As regards the female, our 
specimen does not appear to differ in colour from the corresponding 
sex of Merganetta armata (Des Murs, Icon. t. xlvii.). We are not 
yet acquainted with the female of MW, leucoyenys ; but in all proba- 
bility it would also bear a similar dress. 
The male bird now described was shot and skinned by Mr. Turner, 
a friend of Mr. Whitely’s, near Tinta. We have therefore acceded 
to Mr. Whitely’s request to call it, if new, after his friend’s name. 
The female was obtained by Mr. Whitely himself in the same neigh- 
bourhood.
