338 ON THE GENUS PTILOPUS. 



Duke-of-York Island and on the adjoining parts of New Ireland and New 

 Britain, was one specimen of this bird. I am indebted to Mr. Sclater for 

 the use of a rough proof of the paper read by him at the meeting of the 

 Zoological Society, February 20th, 1877, in which he alludes to this 

 specimen thus : — 



''CEdirhinus insolitus*. 



'' Ptilopus imolituSy ScUegel^ Ned. Tijdschr. i. p. 61, pi. iii. fig. 3. 



^^ Ptilopus humeralis jobiensis (monstr/r), Schlegel, Mus. P.-B. Columbce, p. 16. 



'' CEdirhinus globifer, Cab. et Eeich. Journ. f. Orn. ]876, p. 326. 



" One example of this remarkable Pigeon, from Duke-of-York Island, 

 obtained in October 1875. Schlegel originally described his specimen, with 

 which mine appears to agree in all essential particulars, as from ' New 

 Caledonia,' but subsequently came to the strange conclusion that it was 

 only a monstrous variety of Ptilopus jobiensis ! 



" There can be, to my mind, no doubt of the validity of the species, 

 which I agree with Hrn. Cabanis and Reichenow should even constitute the 

 type of a new genus, readily recognizable by the hard bony protuberance on 

 its forehead. 



"Dr. Hiisker obtained the specimen described by the last-named 

 author in New Ireland, during the voyage of the ^ Gazelle.' " 



In 'The Ibis,' April 1877 (4th ser. vol. i. p. 239), we find that this 

 German expedition conveyed the astronomers of that nation to Kerguelen's 

 Land, for the observation of the Transit of Venus in December 1875, when 

 Dr. Hiisker, the medical officer in charge, obtained in the above-named 

 island, and in other places visited during the voyage round the world (Fiji 

 Islands, New Ireland, New Hanover, Timor, and New Guinea), 143 species 

 of birds, which are enumerated by Messrs. Cabanis and Reichenow f. 



* Drepanoptila insolitus, G. E. Gray^ Hand-list of Birds^ vol. ii. p. 227. no. 9157 (1870).
