the Avifauna of New Caledonia. 267 



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 

 Rev. Canon Tristram, F.R.S. &c. 



The islands visited by Mr. Leopold Layard during his cruise 

 through the New-Hebrides group consisted of Erromaugo, 

 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.
