PSITTIROSTRA PSITTACEA DEPPEIROTHSCH.
(Plate 4, Fig. 3.)
- Psittirostra olivacea Rothschild, Avifauna of Laysan p. 193 (1900—Oahu, ex Lichtenstein nomen nudum & M.S.)
- Psittirostra psittacea deppei Rothschild, Bull. B.O.C. XV. p. 45 (1905—new name for the above, the name olivacea being preoccupied by Ranzani).
Psittirostra Psittacea Psittacea is still one of the commoner birds on most of the Hawaiian Islands, except Oahu, where it was formerly replaced by a closely allied form, P. p. deppei, distinguishable by slightly smaller dimensions, more whitish abdomen in the male, and somewhat more olivaceous upperside. Specimens have been collected on Oahu by Prof. Behn and Herr Deppe, and besides a pair in my collection, I only know of examples in the museums of Berlin and Vienna. There is no trace left of this species in Oahu, and in spite of great efforts Mr. Palmer and all other recent collectors did not come across it. This form has thus shared the fate of Hemignathus ellisianus, Heterorhynchus lucidus, Moho apicalis and Phaeornis oahensis, which have all disappeared from Oahu, while Loxops rufa may still exist in a few pairs, or has possibly followed suit already.
