76 VISCOUNT WALDEN ON THE BIRDS OF CELEBES. 
(7. c.) of the probable cause of the error is most likely correct. Yet it must be borne 
in mind that Labillardiére never set foot on the island of Celebes proper; nor does 
Entrecasteaux’s expedition appear to have had any direct communication with that 
island on either of the occasions of its presence in the Moluccas. On its way from 
Bouru to Sourabaya, in October 1793, the expedition, after failing in its attempt to pass 
the Straits of Tioro, occupied several days in passing those of Boeton, and remained a 
day at the town of Boeton itself. During this period the French naturalist made 
several excursions on shore, and, as he particularly mentions, in the island of Pangasane, 
and one, of two hours’ duration, in the neighbourhood of the town of Boeton. It is 
most probable therefore that this form of Streptocittg was obtained either on the island 
of Pangasane or of Boeton; for the expedition did not touch the mainland of Celebes, 
nor at the island of Saleyer when passing the straits of that name. 
I identify the species which inhabits the district of Macassar with Labillardiére’s bird, 
because it best agrees with his short description. By him the bill is stated to be “ofa 
light black from the root to within one third of the point, the remainder is yellowish.” 
This and the green hue of the black portion of the plumage easily distinguish the 
South from the North Celebean species. The bill is also more slender than that of the 
following species.

I quite agree with Mr. G. R. Gray in regarding this form as specifically distinct from 
the true S. caledonica, from which it differs by its strong, jet-black bill, and by having 
the black portions of its plumage glossed with dark blue. Mr. G. R. Gray (J. ¢.) states 
that the actual individual from which Temminck’s figure was drawn is in the British 
Museum. 
In this species the first quill is barely one inch long; the fourth and fifth are nearly 
equal, the fifth being slightly the longest; the third is somewhat shorter than the 
fourth ; the second still a little shorter than the third. The wing measures 53 inches. 
The second pair of rectrices exceeds the first by $ of an inch; the third the second by 
1}; the fourth the third by 1¢; the fifth the fourth by 14; and the sixth, or middle 
pair, the fifth by 2; the total length of the middle pair is 114; bill from nostril & of 
an inch; tarsus 12. 
Temminck’s surmise that this species occurs in Borneo has not been, as yet, 
realized. 
Professor Schlegel has generically separated his Charitornis albertine from Strepto- 
citta; but it is difficult to seize the characters wherein it generically differs. The 
structure of the wings, tail, and feet is identical. The colouring of the plumage is 
congeneric. The nostrils are similar in form and position. The bill differs in being
