liowever (lilTcront; space round eye brownisli-black with 

 rieh green shades ; surrounding of bill brownish, near it 

 begins a wich» biif(ish-bay band that passes nnder the eye 

 and auricular region, ending at abont half on the sides 

 of neck, near llie auricukir region, where it diminishes, 

 is observed a greenish-black streak which is spread a 

 little in Ihe band; before the bill a bnffish-while mark 

 which snrronnds, as far as nnder the eye, the wide buf- 

 fish-bay band; the latter slightly resembles the design. 

 that the cf üf Teal has in that region ; throat and neck 

 reddish-brown and glossy underneath ; the wide buffish- 

 bay band is almost enclosed by a frame on one si<le by 

 the dark colonr of cheek and neck, and on the other by

 dark tint ends the neck is partly enframed by a buffish-
