78 PROCEEDINGS OF THE NATIONAL, MUSEUM. vol.64. 



There are no specimens available for comparison from either the 

 north or the south, but I am provisionally referring the above series 

 to the southern form, as the relationship of other species from the 

 region seem to point in that direction and the specimens before me 

 do not agree with Meyer and Wiglesworth's description or plate 

 (Birds Celebes, 2, 1898, 500, pi. 33) of Media grata recondita. Their 

 plate shows a bird with the greater and middle wing coverts, tertials, 

 and inner secondaries warbler green like the back, while in the speci- 

 mens before me only the lesser wing coverts are warbler green, the 

 rest of the closed wing being mars brown like the tail; the flanks 

 on my birds are also more extensively warbler green. 



The immature is much like the adult, except it is duller, the chest 

 and belly pyrite yellow, duskier on the flanks, with the feathers of 

 the lower parts obscurely edged with dusky, giving these parts a 

 slightly mottled effect in certain lights. Even the wings and tail 

 are only slightly duller than in the adult. They gradually brighten 

 with age as the adult condition is approached. 



Acts much like a starling in the way it climbs about on moss-covered tree 

 trunks and branches ; flight starlinglike. — H. C. R. 



157. AETHOSTOMA CELEBSlNSIS (Strickland). 



A good series of both sexes from : Paleleh River, August 10, 1914 ; 

 Tandjong Tango, August 28, 1914; Kapas Bay, November 19, 1914; 

 Toli Toll, December 1-4, 1914; Likoepang, March 2-9, 1916; Toe- 

 maratas, July 3, 1916; Laboea Sore, November 28, 1916; Goenoeng 

 lichio, January 18, 1917; Koelawi, February 2-23, 1917; Rano Lin- 

 doe, March 21-25, 1917 ; Pinedapa, January 18-February 15, 1918. 



This series shows quite a little individual variation. An ap- 

 parently adult female (No. 249880) from Toemaratas, has the throat 

 light buff and is approached in this respect by a male from Pine- 

 dapa. Some specimens have the flanks strongly buffy brown and 

 this color even extends across the chest in an indistinct band, while in 

 other specimens the flanks are much less strongly marked with buffy 

 brown and the chest is smoky gray; in a few specimens the lower 

 parts are almost entirely white, with the exception of the grayish 

 wash on the sides and buffy under tail-coverts. Judging from an 

 immature male taken at Koelawi, February 2, not long from the nest, 

 having the chest with obscure dusky spots, the specimens with the in- 

 distinct chest bands are probably birds of the year and the birds with 

 the underparts almost entirely white very old adults. The majority 

 of the series have a dark rictal stripe, more or less distinct, but this 

 is practically absent in a number of specimens. The series from 

 central Celebes when compared with northern birds average a little 

 more brownish on the sides and flanks, yet individual specimens from
