DEFINITIONS

PSEUDONESTOR
(Fringillidae; Ϯ Maui Parrotbill P. xanthophrys) Gr. ψευδος pseudos false; genus Nestor Lesson, 1830, kea; “On behalf of the Hon. WALTER ROTHSCHILD, Mr. E. HARTERT exhibited the type specimens of a new genus and species of Fringilline bird from the Sandwich Islands. Mr. Rothschild proposed for it the name of Pseudonestor xanthophrys.   PSEUDONESTOR, gen. nov.  This genus is nearest allied to Psittacirostra, but differs in the following points:— 1. Male and female are similar in colour and markings, whereas they are quite differently coloured in Psittacirostra.  2. The female is considerably smaller than the male, whereas the sexes are similar in size in Psittacirostra.  3. The principal difference is that, whereas the female of Pseudonestor has a beak similar to that of Psittacirostra though much more curved, the male of Pseudonestor has an enormously hooked bill, much resembling in shape that of a Nestor Parrot, the maxilla being nearly twice the length of the mandible. In Psittacirostra, on the other hand, the bills of the sexes are the same.   PSEUDONESTOR XANTHOPHRYS, sp. nov.” (Rothschild 1893); "Pseudonestor Rothschild, 1893, Bull. Brit. Ornith. Club, 1, p. 35.
