nearly obsolete; tlie tail feathers next to the central pair with the 

 outer webs bordered with and having a subterniinal border of slate 

 gray; and the gray edging to the remiges is more developed in some 

 specimens than others. 



In some lights the top of the head and mantle appear to be 

 darker than the rump, in other positions this difference is scarcely 

 noticeable. This effect seems to be produced by a sheen seen in cer- 

 tain lights ; it is hardly what is usually called iridescent. 



When I described this genus it was compared with Malindangia 

 Mearns, but I neglected to compare it carefully with Edolisoma^ as 

 the color pattern was so different. Comparing it with the latter, the 

 rectrices are more pointed; the bill longer and proportionally more 

 slender: and the texture of the throat more silky. In fact, in 

 structural details, Celehesia seems to be nearly intermediate between 

 Malindangia and Edolisoma with leanings perhaps towards the lat- 

 ter. Nevertheless, Celehesia evidently represents Malindangia in the 

 highlands of Celebes. 



Most of the specimens of Celehesia ahhotti before me have the 

 primaries more or less in process of molt, and it is rather difficult 

 to determine the true wing formula. 



In the original description only the measurement of the type was 

 given and the length of tail inadvertently given incorrectly. Below 

 the extremes and averages of the above series are given : The (seven) 

 males— wing, 105.5-114.5 (109.6) ; tail, 87-103 (94.4) ; culmen, 18-20 

 (19). The (four) females— wing, 103.5-107.5 (105); tail, 87-97 

 (92) ; culmen, 18-18.5 (18.4).

One adult female, Rano R-ano, December 21, 1917 (the type). 

 The original description of this distinct species is as follows: 



Above mummy brown, shading into dresdea brown on the forehead and 

 ■crown ; below dresden brown, shading into buckthorn brown on the bell.y ; a 

 rather broad superciliary line extending back over the ear coverts and widening 

 posteriorly and a spot on the lower .eyelid, black ; upper tail coverts, tail, 

 remiges, and the longer under tail coverts, mars brown; bill (in dried skin), 

 ochraceous orange. Wing, 129; tail, 109; culmen, 25; tarsus, 39: middle toe, 

 26 mm.
