In the ' Annals of the Lyceum of Nat. Hist, of N. York/ as 

 above cited, I pointed out some differences between the birds 

 received from Panama and C. flavigastra from Cayenne. Others, 

 since received, showing these differences to be constant, I am 

 induced to consider them to be distinct species. 



The specimens from Panama are smaller, the upper plumage 

 is of a rather deeper brown, except the rump, which is greyish 

 white, the yellow of the abdomen is rather paler, and the under 

 tail-coverts whiter. 



Male. Length about 5 inches; wing A\ ; tail 2|. 



Female. Wing 3f inches ; tail 2. 



The wings of two specimens of Cotyle ruficollis sive flaviga- 

 stra *, from Cayenne, measured 4f inches ; the sexes of these are 

 not known. 



Fam. DENDROCOLAPTID^. 



2. Dendrornis nana, sp. nov. 



Head above and hind part of neck dark brown, each feather 

 marked in the centre with a small oval tawny spot, these spots 

 becoming elongated in shape behind the neck ; upper part of 

 back and wing-coverts brownish olive; lower part of back and 

 rump bright rufous; tail deep cinnamon-brown; quills dark 

 cinnamon-red, dusky at their ends; under wing-coverts pale 

 cinnamon ; throat and sides of the neck pale fulvous ; breast and 

 abdomen brownish olive, darker on the sides; marked with 

 elongated fulvous spots on the breast and abdomen, these be- 

 coming nearly obsolete on the lower part of the latter; under

 inmy hst of Eraser's collection, P. Z. S. 18fi0, p. 292, as showing differences 

 from C. ruficollis.— Y.h.S.^
