result was that au open shallow nest was constructed, in \^"hich 

 altogether nine eggs have been deposited. We believe that the 

 birds are all females and have all laid eggs in the same nest. They 

 have occasionally sat upon them, but not in a regular manner. 



The eggs are of a dull white colour, with rather a rough texture, 

 and A\-ithout spots of any kind. Eeferring to Layard and Sharpe's 

 ' Birds of South Africa,' p. 552, 1 find it stated that the eggs 

 of this Coly are sometimes streaked, but those laid in the Gardens 

 are perfectly uniform, as will be seen on inspection. 



The Hon. Walter Eothschild exhibited a series of the Parrots of 

 the genus Cyanorhamplms, and made the following remarks : — 



In vol, XX. of the ' Catalogue of Birds in the British Museum ' 

 Count Salvadori enumerates fourteen species of this genus and 

 mentions a fifteenth species, C. hochstetteri (Eeisch.). 



Having a very fair series of most of these birds, and findingthem 

 terribly confused in many of the larger collections, I have thought it 

 might be interesting to exhibit examples of a rare species alive and 

 a good series of those others of which I possess skins. I also have 

 to describe a new form which has hitherto been confounded with 

 C. auriceps (Kuhl). This form differs, it is true, in most respects 

 very slightly from the typical C. auriceps of New Zealand ; 

 but in this genus the birds from the different islands are always 

 constant forms, and therefore I feel justified in separating the 

 Chatham Island bird, and I have much pleasure in naming it after 

 my friend Mr. H. O. Forbes. 



CrAJfOBHAMPHUS FORBESI, Sp. UOV. 



Similar to C. auriceps (Kuhl), but larger and with the crimson 

 band in front of the yellow crown much narrower. The band of 

 crimson in C. auricejjs also reaches the eye, and in some specimens 

 there is also a crimson patch behind the eye, while in my new 

 species there is always a clear space between the crimson band and 

 the eye. 



Hab. Chatham Islands. 



Types in Mus. W. Eothschild. 



From the large number of specimens I have from the Auckland 

 Islands, the Chatham Islands, and both the North and South Islands 

 of New Zealand, I have come to the conclusion that Cyanorhamphus 

 aucklandicus, Bp., and C. rouieyi (Buller), are only synonyms 

 of C. novo? ::ert?«*ifZ?Vp (Sparrm. ); for the specimens from all parts 

 vary in size so much that no two can be found entirely identical in 

 measurements, and no constant dillVrences in colour can be detected. 



Of doubtful species there still remain C. hochstetteri and C. 

 erythrotis, which I think Mr. Forbes was quite right in provisionally 

 uniting under the name of C. erythrotis, for, except the two 

 in the British Museum, we have as yet no authentic specin)ens 

 from the Macquaries. The material from Antipodes Island, I 

 think, is not sufficient to settle the point finally ; and therefore
