1892 ] ON A COLLECTION OF BIRDS FROM TONGOA. 



5 



3 lihipidura, (n. sp.?). 



1 Specimen. 



Leiigth of wiug 80 mm.; the tail is wanting, and the spe- 

 cimen difficult to identify; Dr. Ogilvie Grant, of the British Mu- 

 seum, has examined the specimen, and expresses the opinion, 

 that it probably belongs to a new species. 



It comes rather near Rh. verreauxi, Marie 1870, from New 

 Caledonia, 1 but differs in having no white tips to the wing- 

 coverts; the white margin of the breast-feathers are much wider, 

 the black basal parts of these feathers, so conspicuous in R. 

 verreauxi, being almost hidden. 



4. Myiagra perspicillata, G. E, Gray 1859, 

 var. tannensis, (Tristr. 1879). 



Myiagra tannaensis, Tristr. Ibis 1879, p. 192 (1879). 



Myiagra perspicillata tannaensis, Wiglesworth, Av. Polyn. p. 23 (1891). 



4 Specimens. 



A. Male, nearly adult. 



Greenish black above (some feathers more greyish, like 

 those of the female); head and throat black with steel-greenish 

 gloss; a fe w orange rufous feathers still remain on the sides 

 of the breast. Rest of under surface whitish, very faintly tinged 

 with orange. 



B. Young male (testes small, but distinct). 



The back dark greenish grey, the head a little darker, than 

 the back; throat and fore-neck orange rufous; abdomen whitish, 

 sides of the body rufous. 



Evidently the blackthroated male (adult) and the red- 

 throated (young male) belong to the same species, the black- 

 throated still having some of the orange feathers (of the young 

 stage) remaining on the sides of the throat.
