ART. 16. BIRDS FROM NORTH CELEBES RILEY. 71 



The birds of this series do not agree with the original description ^^ 

 «or that of Meyer and Wiglesworth.-^ The forehead and flanks are 

 much lighter than the rump and base of tail, which is described as 

 cinnamon-red; the white of the throat is continued back beneath 

 the auriculars in a narrow line; the black on the jugulum is a rather 

 large blotch, not a narrow bar, and the feathers on the lower border 

 of this black blotch are tipped with white, forming a rather large 

 spot. It may well be that this is not true R. teysmanni, which has 

 only been found in south Celebes, until quite recently, while the above 

 series is from the north and north-central part of the island. 

 Meyer ^" has reported it from central Celebes without definite locality. 



A young female not long from the nest, with a short stumpy tail, 

 taken at Toewo Mountain, October 28, resembles the adult, except 

 the colors are lighter and the black jugular spot is lacking, its 

 place being taken by a mouse gray band, washed with buffy. 



The black jugular blotch first appears as a narrow band below 

 the white of the throat and gradually increases in size as the bird 

 ages, the white tips only appearing when it becomes fully adult. The 

 unspotted condition of the young in this genus would seem to indi- 

 cate that it is wrongly placed in the family Muscicapidae, or that 

 the spotted condition of the young is not a family character. 



Nine adult males measure as follows: wing 70-76 (73.5); tail, 

 77-84 (81.6); culmen, 9.5-11.5 (10.7); and four adult females: 

 wing, 66.5-69 (67.4) ; tail, 76-80 (78) ; culmen, 9.5-10 (9.9). 



From the above the female appears to be smaller and is slightly 

 duller in color. 



145. CULICICAPA HELIANTHEA HELIANTHEA (Wallace). 



A good series of both sexes: Paleleh River, xA-ugust 10, 1914 

 Ayermadidi, April 4, 1916 ; Goenoeng Kalabat, April 6 and 10, 1916 

 Toemaratas, July 6-8, 1916; Goenoeng Lehio, January 19, 1917 

 Koelawi, February 23, 1917; Lindoe Trail, February 25, 1917; Rano 

 Liindoe, March 9-14, 1917; Toewo Mountain, Besoa, October 26- 

 November 4, 1917; Rano Rano, December 17, 1917. 



The birds from the north in the above series when compared with 

 a series from the Philippines show the latter to rcipresent a recog- 

 nizable race; the Celebes birds are more yellowish and the Philip- 

 pine specimens have more of a greenish cast to the upper surface; 

 below there seems to be little if any difference. The Celebes series 

 averages a little larger. The name for the Philippine form is, ap- 

 parently, CuUcicapa helianthea panayensis (Sharpe). '^
