nine types. After examining them Dr. Gadow comes to tlie 

 conclusion that Loxioides and Psittacirostra are Fringilline 

 forms, and that Acrulocercus and Chatoptila belong to the 

 Meliphagidse, whilst the genera Drepanis, Vestiaria, Hima- 

 tione, Loxops, Clirysomitridops , Oreomijza, and Hemignatlms 

 present common characters which enable them to be dis- 

 tinguished as constituting a peculiar Hawaiian family — 

 Drepanididae. This last-stated fact has been guessed at before, 

 but now rests on solid grounds. Three plates arc well 

 devoted to the illustration of Dr. Gadow's anatomical 

 researches. 



It may perhaps be as well to point out that Lichtenstein^s 

 'Verzeichniss' (referred to under Psittacirostra psittacea, p. 2) 

 is a list of duplicates. It is consequently no argument that 

 because species are not included in it they were therefore 

 " presumably not in the Berlin Museum in 1823 " — only 

 that there were no duplicates of them in the Berlin Museum 

 at that date. 



XIII. — Letters, Extracts, Notices, and Obituary. 



The following letters have been addressed to the Editor of 

 ' The Ibis ' :—

 August 21st, 1801. 



Sir, — It is only just now that I have discovered a mis- 

 print in my paper, " Field-Notes on the Birds of Celebes/^ in 

 'The Ibis' for 1879 (ser. 4, vol. iii. p. 130), which I am 

 bound to correct, as it might mislead other naturalists. I 

 there say, under the head of Criniger aureus, that I discovered 

 this bird on the highest summit of the chief island of the 

 Togian group, in the Gulf of Tomini, ''about 6000 feet 

 above the sea." It ought to be " about 1000 feet " ! 

 If such a high mountain existed on one of the islands of this 

 group, it might induce some one to go there for a successful 

 collection-trip. Now I will not say that it would not be well 

 to go there for that purpose, but at any rate a mountain
