at twenty fathoms (one hundred and twenty feet) below

The geographical range of this bird in the north is very 

 similar to that of the Cormorant ; both go as far as Green- 

 land, but the Cormorant goes also to the eastward, and is 

 found at the Caspian Sea and in India, where the Green 

 species is not seen, but has been brought from South 

 Africa by Dr. Andrew Smith. 



In the adult bird the bill is dusky black, the base of the 

 under mandible and the naked skin about the gape yel- 

 lowish-green ; the irides green ; the head crested in the 

 spring ; the crown, neck, breast, and all the under surface 

 of the body a uniform rich dark green ; back and wing- 

 coverts dark green, each feather with a narrow, but darker 

 margin ; wing and tail-feathers black ; legs, toes, and 

 their membranes black. The whole length of the male 

 is twenty-seven inches ; of the wing from the wrist ten 

 inches and three-quarters. 



Young birds have the upper plumage brown, tinted 

 with green ; the under surface brownish-ash, mingled with 

 white.
