This species is at once distinguishable by the under tail-coverts being black with a slight white margin on each side, and the broad elevated frontal shield, which is divided from the base of the bill by a distinct line * (see fig. 2 ) . It m a y probably be the F. ardesiaca of Tschudi; but it is impossible to state this with certainty, without reference to the original type. It appears to be uncertain whether this species has ever been met with in Chili, although it is called chilensis,-both the specimens described by Hartlaub being from Bolivia, and the only other recorded locality being Ecuador (Fraser) f. Fig. 2. Fulica chilensis. Dr. Schlegel J has united F. chilensis with F. stricklandi (Hartlaub), which is a very different bird, and seems to have thrown back the whole genus into the confusion from which it was rescued by Dr. Hartlaub's admirable memoir. 26.
