In the adult specimens from New Orleans in spirits the 

 head is dark brown, with irregular white spots on the occi-

 the neck, the lower to the hinder end of the beak, and aa 

 intermediate small pale spot on the tympanum ; these 

 marks all become more obscure on the older specimens.

 colouring and from the same locality, vary a little in the 

 comparative width and form of the lobes of the sternum,
