Mr. Layard, in a letter, states his son shot one Tardus 

 pritzbueri in the New Hebrides ; but he has not forwarded the 

 specimen. 



6. Petrceca siMiLis, G. R. Gr. 

 Tanna. 



7. HiRUNDO TAHITICA, Gm. 



Vate Island. 



8. Myiagra melanura, G. R. Gr. 

 Vate Island. 



This is the local race, representing M. viridinitens and M. 

 Juguieri of the neighbouring groups ; but as they seem always 

 distinguishable, they may claim specific recognition.

This species bears exactly the same relation to its repre- 

 sentative chestnut-breasted Flycatcher in Lifu and Ncav Cale- 

 donia that M. melanura does to the other green-black species. 

 In both New-Hebridean species the tail-feathers are without 

 the white which occupies one third of the length of the outer 

 rectrix in the New -Caledonian, and tips and fringes the Lifu 

 species. The other differences are in all respects analogous 

 in the two sets of species ; but the key of the classification, 

 as shown at a glance, is in the tail-feathers. I have long 

 possessed specimens from Aneiteum -, but I had, without ex- 

 amination, united them with M. caledonica. 



10. Artamus melaleucus (Forst.). 

 Vate Island. 



In all respects identical with the bird of New Caledonia. 



11. Grafcalus cinereus (Forst.). 

 St. Bartholomew's Island. 



Identical with the New-Caledonian bird. There is one 

 specimen, obtained by Mr. Layard, Jun., on Mallicolo Island,
