THE GREEN HERON.

about 7 inches ; tail, 3 ; tarsus, 2i ; bill, 2%. [G. N. Lawrence, in Am. Lye. N. Y. VII. 1860, p. 271. 

 Mr. Lawrence adds : " It scarcely ditiers 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 

 tlie throat and neck, also a stripe on the side of the head, white ; these parts in brunncsccns are uniform 

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

 smaller ([uills so conspicuous in virescens."] 



Young (No. 33081, Cuba; Dr. Gundlach. ) : Pileum and occipital crest dull black, 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 b\df. Lower parts dull brown, tinged with light ru.sty ; under-surface of wings uniform dull 

 slate. Upper parts dull gicenish brown, the back and scapulars uniform, tlie wings and tail glossed with 

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

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

 2.50 ; culmen, 2.20 ; depth of bill, .45 ; tarsus, 1.85 ; middle toe, 1.70 ; bare part of tibia, .50. 



This is apparently a very distinct s])ecies, differing from its allies, not only in colors, bitt in strongly- 

 marked peculiarities 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.
