Birds of Celebes: Eallidae. 
age and season, and, apparently, also of sex. Some adults have the remiges evenly 
notched with dull rufous on the inner web, others are hero vormiculated vdth rufous 
and dusky (the notches being broken up); some are more uniform and brighter umber 
above, others have the middles of the feathers darker; in some the chin and cheeks 
are nearly black, in others as much white as black; also the barring of the sides of 
the breast is carried over on to the upper wing-coverts in varying quantities. Our 
two young specimens differ from one another even more, and, further, they do not 
fully bear out the distinctions found by Dr. Sharpe (12) in other young specimens in 
the Leyden Museum. 
Chick. Clothed in silky brown-black down; bill blackish, tip of lower mandible pale, shell- 
chipping point whitish; legs and feet leaden brown; tarsus 18.5; middle toe with claw 
20.5 mm (4 young, about a day old, with mother, Kema, 19. Aug. 93: P.&F. Saras.). 
Claw. The poUex of the chick is furnished with a small claw. This attains to a lai’ger size 
in the adult, and might possibly be of use in fighting. We find this claw in a 
niunbei’ of Ralhne genera before us; it would appear to run through the family. 
Selenka says that it is also found in many diurnal Birds -of -prey, Hiru7ido, 
some Game-birds, as well as in Marsh- and Waterfowl (see, also, Gadow, Diet. B. 
pt. I, 1893, 89). 
Measurements (0 adults, N. Celebes). Wing 139 — 161 mm; tail ca. 55; tarsus 49 — 51; middle 
toe and claw ca. 54; bill from supraloral feathers 31 — 33: in two young specimens 
29.5, 30. 
The specimen with the smallest wing, but not bill, is a female, the largest is a 
male, in the others the sex is not marked. Brom the considerable difference, it is 
probable that the sexes differ in size, the male being larger. 
Distribution. Celebes: — Minahassa (Quoy & Gaimard a 1, Forsten 2, etc.), Gorontalo 
Distr. (v. Bosenberg 2, a 5, Biedel 11), Paguatt (Leyden Mus. 12], Kandari, 
S. E. Celebes (Beccari 5), West Celebes — Dongala and Tawaya (Doherty 16). 
This Bail was one of the species obtained when the “Astrolabe” visited 
Manado in July, 1828. It forms one of a group, consisting of H. sulcirostris 
(Wall.), Sula, ff. Salvad., Salawatti and New Guinea, TJ. Sclat., 
New Britain, and H. torquata (Linn.) of the Philippines. The last is easily dis- 
tinguishable from H. celebensis by its chestnut praepectoral collar and black 
throat and cheeks; H, sulcirostris and .saturata are less easily separable, but both 
have the cheeks and throat jet-black and H. saturata is said to have a longer 
and stouter bill, and its tarsus measures, according to Salvadori, 53 — 57 mm. 
This species seems to be rarer in North Celebes than its ally Hypotaenidia 
philippensis, and, so far as we know, it has not yet been recorded from the 
Southern Peninsula, though Beccari found it in the South-east, and Doherty 
in the West.
