DEFINITIONS

DYSMORODREPANIS
‡ (Fringillidae; Ϯ Lanai Hookbill D. munroi) Gr. δυσμορος dusmoros  ill-fated  < δυσ- dus-  hard, bad; μορος moros  fate; genus Drepanis Temminck, 1820, mamo; "DYSMORODREPANIS, gen. nov.  Nearest to Psittacirostra, but distinguished primarily by the form of the beak. Maxilla strongly decurved, compressed so as to be cariniform, and extending beyond the mandible for a distance equal to one-third (or more) of its full length. The nostril is subreniform, the lower margin of the operculum being rounded; numerous antrorse pale setiform feathers project over it from the base, and a few black setæ, longer than these, reach right to the apex. Seen in profile the mandible has its upper and lower margin subparallel on the basal part, but before the middle of its length they curve strongly upwards. The tip alone is received in the maxilla, about midway between its apex and the nostril, so that for most of the length of the mandible there is a free space between its edge and that of the maxilla and no co-adaptation at all.  ...  Dysmorodrepanis munroi, sp. n.  ...  When I collected on Lanai in 1893 and subsequently the forest was in a deplorable condition, being rapidly destroyed by countless wild goats, and it was also full of wild pigs and cats that had run wild. The latter, as I have elsewhere recorded, were destroying native birds wholesale" (Perkins 1919); "Dysmorodrepanis Perkins, 1919, Ann. Mag. Nat. Hist., ser. 9, 3, p. 251. Type, by monotypy, Dysmorodrepanis munroi Perkins." (Greenway in Peters, 1968, XIV, p. 101). The Lanai Hookbill, known from only one specimen collected in 1913, was for long treated as an aberration or hybrid.
Var. Desmodrepanis.
