* There is much intricacy with respect to the subdivision of M. lUiger's 

 genus Nectarinia. I have adopted Mr. Swainson's suggestion of applying 

 Nectarinia to the Honey-suckers of America, and Cinnyris to those of the Old 

 World. This mode will answer for the present : but a complete revision 

 of the group is much wanting. I do not feel quite satisfied respecting the 

 situation of M. Vieillot's genus Furnarius. 



f This extensive and extraordinary family is at present in much confusion. 

 I hope shortly with Dr. Horsfield's assistance to place it in some order. We 

 have just characterized several distinct forms belonging to it, in the Linnean 

 Society's Collection.
