This series, while showing quite a little variation, agrees in being darker 

 and smaller than Australian birds; the throats are noticeably of a deeper 

 buff, more pinkish. From Anas superciliosa pelewensis, the Celebes bird 

 differs in being larger with the buff of the throat more extensive. Of Anas 

 superciliosa superciliosa my series is small and useless for comparison, but 

 as this race is said to be even larger than that from Australia, comparison 

 is not necessary. 



Megalurus celebensis, sp. nov. 



Type, adult male, U. S. National Museum, No. 252,087, Besoa, Celebes, 

 October 23, 1917. Collected by H. C. Raven (original No. 4551). 



Similar to Megalurus amboinensis but larger, with the back more heavily 

 streaked with blackish, the cinnamon edges of the tertials broader, the 

 nape obscurely streaked with dusky, the blackish streaks on the wing- 

 coverts broader, the lower back, rump, and upper tail-coverts streaked 

 with brownish black, and the buffy chest band more pronounced. Wing, 

 67; tail, 113.5; culmen, 12 mm. 



Remarks. — Only two specimens were taken at the type locality and on 

 the same day; a male and female. The female is smaller than the male 

 with the streaks on the head extending onto the forehead and the black 

 streaking on the back narrower. A male specimen of Megalurus amboinen- 

 sis, with which the above species has been compared, has no streaks on the 

 nape whatever, the top of the head is a deeper sayal brown, and the lower 

 back and rump are without streaks, only the upper tail-coverts having 

 narrow dark shaft streaks. It measures: wing, 61; culmen, 12 mm. 



This genus has not been hitherto recorded from Celebes. 



Dicruropsis montana, sp. nov. 



Type, adult male, U. S. National Museum, No. 252,150, Besoa, Celebes, 

 October 28, 1917. Collected by H. C. Raven (original No. 4586). 



Similar to Dicruropsis leucops but much smaller, especially the bill and 

 feet; the metallic colors duller, more bronzy, and spots on the chest re- 

 duced in size; the .tail more forked, the feathers narrower, and the outer 

 pair less flared outwardly. Wing, 131; tail, 138; culmen, 24; tarsus, 19; 

 middle toe, 14 mm. 



Remarks. — The present species is founded upon a male and female from 

 the type locality, a female from Rano Rano, and a female from Goenoeng 

 Lehio. All the above localities are in the mountains, in the general region 

 of Lake Lindoe, which is the unnamed lake on Meyer and Wiglesworth's 

 map 1 to the northwest of Lake Posso. 



In this genus there is practically no difference in color between the 

 sexes and very little difference in size; females average slightly smaller. 

 The three females of Dicruropsis montana measure as follows: wing, 133.5- 

 140 (137.5); tail, 133-152.5 (142.2); culmen, 24-24.5 (24.3); tarsus, 19.5- 

 20 (19.7); middle toe, 14-14.5 (14.2). Nine females of Dicruropsis leucops 

 measure: wing, 154-167 (159.4); tail, 131-150 (138.6); culmen, 29-35.5
