* I have adopted Mr. Swainson’s generic name of Hematornis in pre- 
ference to the one given by Temminck, which Mr. Strickland thinks should 
be employed, though in a restricted form. M. 'Temminck first noticed his 
division in the letter press of Pl. col. t. 137, under the French name of 
Merles Turdoides, but he did not give a Latin name until t. 380, which was 
published some time afterwards. In the latter place he informs us, that his 
deceased friend Kuhl had given a designation to this group (Pyenonotus) 
from the downiness of the uropygium, but which he proposes should not be 
adopted, as all the species of this subfamily are more or Jess furnished with 
down on that part: he therefore applies the ‘‘more vague term of Jzos,” 
thus showing that these groups are identical; for which reason Temminck’s 
name should at all events be cancelled. 
If this had not been the case, I could not have retained the word Jzos, as 
proposed by Mr. Strickland, because I do not consider it correct for writers 
to restrict genera unless with the original type. All other restrictions must 
necessarily cause difficulties to students, inasmuch as they would have to 
learn whether Jos, for example, is to be looked upon as the genus of the 
original founder, or the restricted one of some modern writer, and applied 
perhaps to birds of very different characters from the proper type.
