Obs. The beak is more tumid and the under mandible more de- 

 veloped in this well-marked type than in any other of the Tanagrina, 

 and it has hence been referred to the genus Pyrrhula. The mar- 

 ginal notch, however, together with the blue and silky plumage, and 

 the geographical distribution, sufficiently prove the true place of this 

 bird to be among the Tanagers, and in the vicinity of Tanagra, Lin. 

 (restr.), and Calospiza, Gray {Aglaia, Sw.).

 The genus Brachylophus, as denned by Mr. Swainson, includes 

 three very distinct groups : first, the Green Woodpeckers, which had 

 previously been named Gecinus by Boie; secondly, the crimson- 

 winged species, miniatus, puniceus, and mentalis, to which I propose 

 to restrict Swainson's name Brachylophus; and thirdly, the short- 

 thumbed Woodpeckers, which are here characterized.
