538 MESSRS. SCLATER AND SALVIN ON THE CRACID&. [June 9, 
We were much puzzled as to the difference between this species 
and O. vetula until we had examined the specimens already recorded 
as having been obtained by Mr. le Strange in the vicinity of Mexico ; 
and our American friends appear to have been in equal perplexity 
upon the subject. But upon comparison of examples of the two 
species all doubt vanishes, and the accuracy of Wagler’s views 
becomes at once apparent. The present bird is at once distinguish- 
able from O. vetula by its larger size, its white belly, and especially 
by its very long tail. 
The Smithsonian collection contains two examples of this species, 
obtained by Xantus on the Rio de la Armeria and Tupila River in 
1863.

We have examined a large series of specimens of this Guan, in- 
cluding the types of O. maccalli and O. plumbeiceps. We were at 
first inclined to allow the latter (established by Mr. Gray upoti 
Guatemalan specimens)to be distinct, from its smaller size and from 
the fulvous colouring of the terminations of the rectrices. In 
northern and central Mexican specimens, including the type of O. 
* Next to this species must be inserted a new one, of which a single skin has 
lately come into our possession :—

Hab. Valle Dupar, on south side of the Sierra Nevada of S. Martha, at an 
elevation of 400 feet (Joad).

Obs. Similis O. vetule, sed crisso rufo et rectricum apicibus latius albis distin-

Mr, Joad, F.Z.8., obtained two examples of this Ortalida in December 1863, 
during his expedition in the vicinity of S. Martha. Only one skin was preserved, 
which is now in the collection of Salyin and Godman.
