P. d. cincinna/tus. (Lat. cincinnatus, having curly hair.) WHITE-TUFTED CORMORANT.

lateral crests, of a superciliary bundle of long curly filamentous feathers. Larger: size of

30.00 or less; extent 45.00; wing 19.00 or less; tail 6.00 or less; tarsus a little under 2.00; 
but bill as large if not larger; gape nearly 4.00. The plumage is exactly the same. There 
are said to be certain differences in the life-colors of the bills (blue instead of yellow on under 
mandible and edges of upper— Audubon), but none show in my specimens. This is simply 
a localized southern race of dilophus, smaller in general dimensions, with relatively larger bill,
