 Mr. Lawrence adds : " It scarcely lUffers from B. virescens, of which it is a remarkable representative, 

 but unmistakably distinct. The plumage generally is darker than in virescens. In the appearance of their 

 upper parts the two species closely resemble each other, but virescens has the chin and a central line down 

 the throat and neck, also a stripe on the side of the head, wdiite ; these parts in hninncscens are uniform 

 in color, with no trace of white. This species is also without the light edgings to the wing-coverts and 

 smaller quills so conspicuous in virescens."] 



Young (No. 33081, Cuba; Dr. Gundlach. ): rileuni and occipital crest dull blade, with a slight 

 bottle-green gloss ; rest of head and neck dull ferruginous, the malar and post-ocular regions streaked 

 with black, the central line of the throat and foreneck with indistinct dusky streaks and narrower ones 

 of light bufJ'. Lower parts dull brown, tinged with light rusty ; undcr-surface of wings uniform dull 

 slate. Upper parts dull greenish bi-own, the back and scapulars uniform, the wings and tail glossed with 

 bottle-green, all the coverts bordered with ferruginous ; primary-coverts and piimaries uniform slate with- 

 out trace of whitish tips; secondaries and tail uniform dark metallic bottle-green. Wing, 6.40; tiul, 

 2.50 ; culmen, 2.20 ; depth of hill, .45 ; tarsu.s, 1.85 ; middle toe, 1.70 ; bare part of tibia, .50. 



This is apparently a very distinct species, differing from its allies, not only in colors, but in strongly- 

 marked peeuliaiities of form. We have never seen the adult, the only specimen in the National Museum 

 being an excellently mounted full-grown young bird of the year, presented by Dr. Gundlach.
