REMARKS

D E N D R 0 COL APTINJE, 
WITH 
DESCRIPTIONS OE TWO NEW GENERA AND SPECIES. 
By T. C. EYTON, Esq., F.L.S., F.Z.S., &c. 
The above mentioned family of birds lias been very variously clas- 
sified ; by Mr. Swainson they were included among the Certhianat, 
by Mr. Gray they have been made into a separate sub-family, which 
appears to be their natural rank. The latter author, however, has 
suppressed several genera which appear to be distinct, and suffi- 
ciently defined, such as Dendrocops and Dendroplex of Swainson. 
Mons. Lafresnaye, in his admirable papers on the group, con- 
tained in the Revue et Magazin de Zoologie, divided them into eight 
genera, and in a former number of these Contributions I added 
another under the name of Dendrexetastes to these. I propose to 
add two more, Drymornis and Dendrornis. The latter genus com- 
prehends all the straight billed species, classed by Mons. Lafres- 
naye under Nasica, thus restricting that genus to N. longirostris. 
The former genus comprehends Nasica bridgesii , figured in the 
Contributions, and Xiphorkynchus pucker ani, figured in 0. des Murs 
Iconographie Ornithologique. The family contains about sixty well 
defined species, which I propose to divide as follows : 
DENDROCOLAPTES, Herm. 
Bill arcuated, laterally compressed, of moderate length, not 
notched at the tip, strong, the birds of large size, fourth quill- 
feather longest.
