Mr. Everett sent a fine series, collected in October and November in 

 South Flores from the low country np to 3500 feet. Most of the specimens 

 sexed " ? " by the native hunters are smaller, the wing only about fi" mm., 

 and the markings on the forehead are less distinct. A male nestling is paler, 

 with the forehead and crown uniform buff, without tlie black centres, which 

 give the old bird a striking scaly appearance. The old birds have a bare spot 

 behind the eye. 



*22. Zosterops superciliaris Hartert. 

 (Plate III.) 



? ad. Crown greenish olive, with a dark brown wash. Utmost base of 

 forehead just above the nostrils and lores pale sulphur-yellow ; superciliary line 

 from lores over eyes to end of head sulphnr-yellow. The usual Zosteropine white 

 ring round the eyes conspicuous and broad ; sides of head olive-grey, with a silvery 

 gloss. Rest of upper surface olive-green, brighter green on back and rump. Quills 

 dark brown : inner lining very pale yellow ; onter edges light olive-green. Below 

 sulphur-yellow ; sides of breast, flanks, and thighs with an olive-green wash. Total 

 length about 127 mm. ; wing 67 — 69 ; tail 52 — 53 ; culmen from base of forehead 

 16; exposed part of culmen 12; tarsus 19'9. cj ad. like ?. {Antea, ^i. 172.) 



A series from 3000 to 3500 feet in the hills of South Flores. A young 

 female just out of the nest resembles the old birds, but is duller and less distinctly 

 marked, the yellow superciliary line not developed, the ear-coverts dull olive. 



*23. Zosterops citrinella Bp. 



Two specimens, both marked " c? " by native collectors, have the wings only 

 36 mm., while those from Savu and most from other localities have the wings 

 about 2 mm. longer. A large series of Z. citrinella from Flores might enable tlie 

 " fearful splitter " to separate them subspeciiically. The type is from Timor. 



•24. Zosterops aureifrons Wall. 



A fine series from the low country. This species had been discovered in Flores 

 by Wallace. 



*25. Zosterops unica sp. nov. 



This new Zosterops is evidently nearest to Z. intermedia Wall., but differs con- 

 siderably in its much smaller size and in the bright yellow colour of the lower rump 

 and upper tail-coverts. The tail is pure black. The upperside is also slightly more 

 yellow, and the sides of the body are a little more distinctly washed witli olive. 

 Although only one skin, the sex of which is not determined, from Nauga Hamau is 

 to hand, we need not hesitate in describing this bird as new, the bright yellow spot 

 on the rump and its small size and black tail being striking characters to distinguish 

 it. The beak is darker than in nearly all Z. intermedia before me, and I may say 

 that we have a very large series of it. Total length oi Z. unica about 98 mm. ; wing 

 51 (against 56 to 57 as the smaller measurements of the wings of Z. intermedia): 

 tail 35 ; exposed part of culmen 9 ; tarsus 15. The specimen in spirits mentioned 

 by Buttikofer as coming from Maumeri jirobably belongs to Z. unica.
