ART. 16. BIRDS FROM NORTH CELEBES RILEY. 87 



on the outer web with argu.s brown, but this color not quite reaching the tip ; 

 upper tail-coverts, argus brown ; below buffy brown, lighter on the chin and 

 with a pronounced lemon j'ellow wash on middle of belly ; under tail-coverts 

 ochraceous-tawny ; wings prout's brown, the inner webs of the primaries and 

 outer secondaries fuscous ; under wing-coverts grayish olive with a slight 

 yellowish tinge along the margin of the wing; the reraiges where they rest 

 against the body narrowly bordered with light ochraceous buff. 



The wing and tail in the type specimen are in partial molt. The only female 

 that has an apparently perfect tail has it slightly rounded. 



The two females measure: Wing, 77.5-81; tail, 66.5-69; culmen, 

 12-13.5 mm. 



The two females are much alike above, one is only slightly washed 

 with brussels brown on the back; below the Rano Rano specimen is 

 much lighter with a much more pronounced wash of yellow on the 

 abdomen and the under tail-coverts are lighter. 



The immature male is light below like the Rano Rano female but 

 with the yellow wash on the abdomen very pale and only slightly 

 indicated; above it is more of an olive brown. A few dark feathers 

 are appearing on the pileum and sides of face and a few maliogany 

 red feathers over each shoulder on the back. 



Family ZOSTEROPIDAE. 



SILVER-EYES. 

 169. ZOSTEROPS SARASINORUM Meyer and Wiglesworth. 



Nine males and four females, Goenoeng Kalabat, 1,830 meters, 

 April 7-11, 1916; one male, Toemaratas, July 9, 1916; two males 

 and two females, Toewo Mountain, Besoa, October 26-27, 1917 ; one 

 female, Rano Rano, December 9, 1917. 



In the above series an occasional specimen shows an incipient yel- 

 low streak down the center of the breast. 



Birds from the central mountains (Besoa-Rano) do not seem to 

 diifer from those from the type locality (Kalabat). 



170. ZOSTEROPS INTERMEDIA Wallace. 



A fair series from Koelawi, February ^23, 1917; and Rano Lin- 

 doe, March 4^24, 1917. 



Specimens from south Celebes (the type locality of the species is 

 Macassar) are not available for comparison. The adults from central 

 Celebes do not exactly fit the descriptions consulted, as for instance 

 there is a dusky loral streak in all the specimens examined by me. 

 Two specimens in the United States National Museum from Dodepo 

 Island, Gulf of Tomini, are much lighter above and below with the 

 loral streak less well defined and have larger bills than the series 

 taken by Raven. It may well be that there is more than one form of 

 the species in Celebes.
