ZOSTEROPS ALBOGULARIS (Gould). 



1 1 ^IIITE-BREA STED ZOSTEEOPS. 

 fJlHIS is one of the two species of the genus Zosterops which is peculiar to Norfolk Island. 



Except in the colouring-, there is no material difference between this bird and others of the 

 same genus. As with the others, the plumage of the sexes is alike. 



All the upper surface and wing-coverts are olive-green, with a strong tinge of chestnut on 



the back ; the wings and tail, brown, with a margin of green ; a zone of white surrounds the eye, 



and is bounded in its turn by black ; the throat, chest, and centre of the abdomen, white ; flanks, 

 pale chestnut; irides, brown; bill and legs, lead-coloured. 



Total length, 5| inches; bill, § inch; wings, 3 inches; tail, 1\ inches; tarsi, 1 inch. 



Habitat : Norfolk Island. 



ZOSTEROPS TENUIROSTRIS (Gould). 



SLENDER-BILLED ZOSTEROPS. 



NEXT to Zosterops Strenuus, this is the largest species of the genus. The length of the bill, and 

 greater slenderness and elegance of shape than its congeners, have suggested the specific name 

 of " Tenuirostris " as most suitable. 



Like the White-breasted Zosterops, this is an inhabitant of Norfolk Island. 



Very little is known of the habits of this bird, and it is therefore impossible to say if they 

 are the same as those of other members of the same uenus. 



The head, all the upper surface and wing-coverts, olive-green, with a tinge of dark brown on 



the back ; wing and tail feathers, brown, bordered with green ; throat, yellow, with a patch of red in 



the centre ; abdomen, pale yellow ; bill and legs, light brown ; eye surrounded by a zone of white, 

 which is bounded by blackish-brown. 



The sexes are alike in plumage. 



Total length, 5| inches; bill, f inch; wing, 2| inches; tail, 2| inches; tarsi, f inch.
