Mr. Gould informs me that he has recently examined specimens 
of this bird killed near Bogota. Its occurrence as far south as Nica- 
ragua a already been noticed by Prince Bonaparte. (Notes Orn.

This duck seems to extend from the most southern portions of the 
South American continent into Texas and as far north as Louisiana : 
see Cassin’s Illustrations, pt. 3. pl. 15. Ihave a female from Bogota, 
and the MM. Verreaux have received examples of the same bird 
from Santa Martha.

2. On some New Species or BirpDs COLLECTED BY Mr. 
M‘Gitiivray. By Jonun Govutn, F.R.S. etc. 
In exhibiting a portion of the first collection of birds which has 
been sent to this country by Mr. John M‘Gillivray, the naturalist 
attached to H. M. surveying ship ‘ Herald,’ Captain Denham, I have 
to remark, that it comprises several species of especial interest, 
particularly some obtained on the Isle of Pines, and on Lord 
Howe’s Island. It also comprises a new form among the Twr- 
dide or Thrushes, from that isolated spot the island of Tristan 
d’Acunha, which presents a union of the characters of the genera 
Turdus, Chameza and Oreocincla. This new bird I propose to 
characterize under the generic and specific appellations of Nesocichla 
eremita. Among the birds from Lord Howe’s Island is a singular 
species of Merula or Blackbird, nearly allied in form to, but very 
different in colour from, the Merula nestor of Norfolk Island; to 
this species the specific name of vinitincta is assigned. From the 
same island are two distinct species of Zosterops, entirely new to 
science. They differ from any other species of the’ genus which has 
come under my notice, one of them being a very large bird for a 
Zosterops, and the other a much smaller species, being nearly allied 
to, but distinct from, the Australian Zosterops dorsalis: to these
