the Avifauna of New Caledonia. 
Genera common to New Caledonia and Australia, but not 
found in Fiji, 27 (this includes Waders and Sea-birds). 
Genera found in New Caledonia and Fiji not found in Aus¬ 
tralia, 2. 
Genera common to all three countries, 29. 
Genera found only in New Caledonia, 6. 
Genera found only in Fiji, 4. 
Species common to New Caledonia and Australia, but not 
found in Fiji, 33. 
Species common to Fiji and Australia, but not to New 
Caledonia, not one! 
From this analysis it is evident that New Caledonia is 
essentially Australian. We have not materials enough yet 
to institute a proper comparison with the avifauna of the 
New Hebrides and other islands to the northward and east¬ 
ward ; but what little we have shows that it differs considerably 
from ours, and that this is probably the most easterly limit 
of the Australian avifauna. 
XX.— Notes on some Birds collected or observed by Mr. E. 
Leopold C. Layard in the New Hebrides. By Messrs. E. 
L. Layard, and E. L. C. Layard. With Remarks by the 
Bev. Canon Tristram, F.E.S. &c. 
The islands visited by Mr. Leopold Layard during his cruise 
through the New-Hebrides group consisted of Erromango, 
Vate, Ambrym, St. Bartholomew, Santo, Api, and Mallicolo. 
The major part of the collection was formed on Vate (or 
Sandwich Island), in the neighbourhood of Havanna Harbour, 
the time spent on some of the others having been too limited 
to do more than note such birds as were seen and fully 
recognized. The number of species of which examples were 
collected amounts to twenty-five, those seen and noted to 
thirty-eight. In the tabulated list appended the numerals 
indicate the numbers procured, the asterisk that the species 
was observed but not procured. •
