Sore, November 19, 1916; Koelawi, January 27-28, 1917; llano 

 Lindoe, March 5-19, 1917; Tamboe, June 13, 1917; Gimpoe, August 

 3-23, 1917; Toare, September 20-23, 1917; Pinedapa, January 13 and 

 February 8, 1918. 



There appears to be no constant differences in birds from the 

 north and the north-central mountainous country. 



Two immature specimens, male and female, from Manembo Nembo, 

 June 23 (249789-790), in worn abraded plumage, with short crests, 

 have the scapulars, lesser wingcoverts, tips of the remiges, occiput, 

 ear-coverts, and a central band down the rump cinnamon-brown; 

 the backs have begun to acquire the shining bluish black of the 

 adults; the chin blackish; the crest has begun to develop slightly; 

 the male has the chest spotted with brownish, the female not; the 

 breasts have a brownish cast ; the tails are much as in the adults, ex- 

 cept the feathers are tipped with brownish. Another stage of the 

 immature is much like the adult, except only the chin is black, there 

 is a band of black spots across the chest, and the white on the hind 

 neck is less developed. Still another stage of immature has no black 

 on the chin whatever and no chain of black spots across the chest 

 and evidently represents an older stage than the above, as they were 

 taken later in the year (Gimpoe, August 10, 252556-252257). 



195. ENODES ERYTHROPHRYS ERYTHROPHRYS (Temminck). 



A good series of both sexes from Goenoeng Kalabat, 1,700 meters, 

 April 6-9, 1916, and Toemaratas, July 4 and 9, 1916. 



196. ENODES ERYTHROPHRYS CENTRALIS Riley."* 



One male, the type, Goenoeng Lehio, January 13, 1917 ; one male, 

 Winatoe, January 21, 1917 ; one male and two females, Lindoe Trail, 

 February 28, 1917; three males and two females, Toewo Mountain, 

 Besoa, October 29-November 3, 1917 ; one male, Kano Rano, December 

 28, 1917. 



All the specimens from the northern part of the island have the 

 peculiar superciliary feathers flame scarlet, while the above series 

 from the north central region has them orange chrome; this is the 

 most striking difference and seems to be constant, although there are 

 other minor and inconstant characters that are only average. For 

 the above reason 1 have ventured to separate the north-central bird, 

 ■with the following description: 



Similar to Enodes erythrojihrys erythrophrys, but superciliaries orange 

 chrome, not flame scarlet; rump and crissum lighter yellow; outer margin of 

 wing feathers and upper surface of tail more greenish ; and wing and tail 

 shorter. Wing, 109 ; tail, 106.5 ; culmen, 19 ; tarsus, 26.5 ; middle toe, 21.5 mm.
