504 MR. D. G. ELLIOT ON THE GENUS PTILOPUS. [May 7, 



1853. Jaccuinot and Pucheran, 'Voyage au Pole Sud'(text). 

 Young of Pt. luteovirens described as Pt. felicice. 



1854. Bonaparte, in the ' Comptes Rendus.' 



In a paper contributed to this Journal, Bonaparte divided the 

 then known species of Ptilopus into various genera as follows : — 

 Leucotreron, Cyanotreron, Rhamphiculus, Omeotreron, Kurutreron, 

 Thouarsitreron, Lamprotreron, Iotreron, and Ohryscena. These 

 are founded mainly upon the coloration of plumage (a dangerous 

 character (?) always), and in this case not particularly well selected. 

 In the case of Rhamphiculus and Omeotreron, the former is created 

 for the young (!), and the latter for the adult (!), of Ptilopus occipi- 

 talis ; and in Cyanotreron is placed the female (!) of Ptilopus su- 

 perbus, while the male (!) of the same species is made the type of the 

 genus Lamprotreron. In Omeotreron, also, is placed the young of 

 Pt. luteovirens, while the adult is the type of the genus Chryscena ! 

 It does not appear to me necessary, or even advisable, to adopt any 

 of this author's genera for this group. 



1854. Bonaparte, in the 'Comptes Rendus.' 



The young of Pt. occipitalis is called Pt. batilda, and Pt. apicalis 

 is first described. Species 32. 



1855. DesMurs and Prevost, 'Voyage de la Venus.' 



Pt. mercieri and Pt. temminckii first described. Species 34. 



1855. Bonaparte, in the ' Comptes Rendus.' 



Pt. leclancheri described as Trerolcema leclancheri. Species 35. 



1856. Gray, 'List Birds British Museum.' 



Among the members of this genus here recorded Pt. greyi is 

 named but not described. Species 36. 



1856. Gould, ' Proceedings of the Zoological Society of London.' 

 Pt. eugenics from the Solomon Islands described. Species 37. 



1857. Bonaparte, 'Conspectus Generum Avium.' 



In this publication this author made a subfamily of this group, 

 and divided it into the genera proposed by him in the ' Comptes 

 Rendus' three years previously. Pt. xanthogaster, Wagl., is called 

 diademata, after Temminck ; Drepanoptila holosericea is placed 

 in the genus Lamprotreron with superba and porphyreus ! In Pti- 

 lopus are purpuratus, Wagl., as porphyraceus, Forst., ex Tonga- 

 Tabou ; regina, Swains., as swainsoni, Gould ; Pt. ewingii, Gould, 

 from Timor, is separated as fiavicollis, after Gray ; Pt. coralen- 

 sis, Peale, redescribed as viridissimus ; the species ex Vanikoro (!) 

 (errore) called purpuratus, Wagl. [this bird comes from Balaou, 

 not Vanikoro, and was afterwards named bonapartei by Gray] ; 

 Pt. roseicapillus, mercieri, fasciatus, Peale (as clemcntince, Hombr. & 

 Jacq.); perousii, Peale (as marice, Hombr. & Jacq.); pulchellus and 

 apicalis. Cyanotreron has cyanovirens (= superbus, Temm., $) 

 and monachus, Temm. Iotreron contains viridis, Linn., melano- 

 cephalus, Gmel., rivoli, Prev. & Knip, iogaster, Temm., and nana,
