(Cacatuidae; Ϯ Long-billed Black Cockatoo Z. baudinii) Etymology undiscovered; perhaps an eponym; Gregory Mathews’s manuscripts, referred to by Richmond 1917, indicate that Zanda is an Australian aboriginal name (cf. Old Persian zanda beautiful girl) (see zanda); "ZANDA, gen. nov. Differs from Calyptorhynchus in its very flat, narrow bill and different wing-formuli—3rd, 4th, and 5th longest and subequal, 1st shorter than 5th. Type, Calyptorhynchus baudini tenuirostris Mathews." (Mathews 1913).
