Show 1893.] HON. W. ROTHSCHILD ON THE GENUS CYANORHAMPHUS. 529 result was that an open shallow nest was constructed, in which altogether nine eggs have been deposited. W e 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 without spots of any kind. Referring to Layard and Sharpe's ' Birds of South Africa,' p. 552, I 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 Rothschild exhibited a series of the Parrots of the genus Cyanorhamphus, 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, G. hochstetteri (Reisch.). 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 N e w 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. CYANORHAMPHUS EORBESI, sp. nov. 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. auriceps also reaches the eye, and in some specimens there is also a crimson patch behind the eye, while in m y new species there is always a clear space between the crimson band and the eye. Hab. Chatham Islands. Types in Mus. W . Rothschild. From the large number of specimens I have from the Auckland Islands, the Chatham Islands, and both the North and South Islands of N e w Zealand, I have come to the conclusion that Cyanorhamphus aucklanclicus, Bp., and C. rowleyi (Buller), are only synonyms of C. novae zealandice (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 differences in colour can be detected. Of doubtful species there still remain 0. hochstetteri and C. erythrotis, which I think M r . Forbes was quite right in provisionally uniting under the name of C. erythrotis, for, except the two in the British Museum, w e have as yet no authentic specimens from the Macquaries. The material from Antipodes Island, I think, is not sufficient to settle the point finally ; and therefore |
