436 ON A NEW SPECIES OF TRICHOSTOMA. [1876. 



the Macassar bird, supplied the type of T. celehense, Strickl. : consequently the Macassar form 

 Il)is. 1S76, requires to be distinguished by a separate title; and for it I propose that of Trichostoma Jinschi 

 (Plate XI. fig. 1, in orig.). It may be thus described : — 



S (Macassar). Chin and throat white, faintly tinged with very pale fulvous. Breast, 

 abdomen, flanks, under wing-coverts, and thigh-coverts fulvous, tinged with rufous, pale near the 

 mesial line. Under tail-coverts rusty fulvous, redder than the abdominal plumage. Head 

 umber-brown, with a slight olive tinge. Space before the eye greyish white. Cheeks fulvous 

 white. Back and uropygium rufous brown, the uropygial feathers being voluminous and fluffy, 

 and terminally coloured pale rusty fulvous. Upper tail-coverts pure rust-colour. Quills and 

 rectrices ruddy brown, the outer webs being distinctly rusty brown. The inner webs of the third 

 and following quills with a pale rusty fulvous edging for part of their length, this edging being 

 indicated at the base of the second quill. Wing-coverts ruddy brown. Legs, feet, claws, and 

 lower mandible (in dried skins) pale yellowish white. Upper mandible horny brown, commissure 

 and tip pale yellowish white. Iris (labelled) yellow. Wing 2'87 inches, tail 2-25, tarsus I'O. 

 Rictus armed with very long bristles. First primary short, second about half an inch longer, 

 third three eighths longer than second ; fourth, fifth, and sixth longer than third, the fourth and 

 sixth being nearly equal, and the fifth the longest. 



T. celehense, Strickl. (Menado) (Plate XI. fig. 2, in orig.). Whole head above, nape, back, 

 uropygium, and major wing-coverts rich reddish brown, purer brown on the head. The long loose 

 uropygial feathers tipped with ferruginous. Rectrices and outer webs of the quills dark ferru- 

 ginous chestnut (in another example the outer webs of the quills concolorous with dorsal 

 plumage) ; inner webs brown. Lores ashy white. Cheeks and ear-coverts brown. Chin, throat, 

 and ventral region white or ashy white. Breast pale cinereous. Flanks brown. Thigh-coverts 

 and under tail-coverts light rust-colour. Upper tail-coverts bright ferruginous. Legs, feet, and 

 claws pale yellowish. Base of maxilla blackish brown ; remainder, with mandible, pale horn- 

 colour. Rictal bristles black, not very stiff, and extending beyond the basal half of the bill. 

 Ibis, 1876, Wing 21b inches, tail 2-37, tarsus -93, bill '75. Gradation of quills as in T.Jinscki. 

 ^' ' The examples described by Dr. F. Briiggeman (Abhandl. nat. Ver. Bremen, v. p. 63. no. 57) 



appear to be T. celehense, Strickl., according to my views. 



Pb^ ig^g Letter on Sterna albigena, //'Owi Viscount Walden, P.Z.S., to tlie Editor of 



P-384. ' 'The Ibis' (July 1876). 



Sir, — A couple of examples of the rare Tern, Sterna alhigena, Riipp., shot on the Bombay 

 coast near Hurnee C?) on the 25th March, 1875, have recently come under my notice, and have 

 been identified by our best authority on the Sterninae, Mr. Howard Saunders. This Tern has, 

 I believe, been only known to inhabit the Red Sea ; and as it forms an addition to the fauna of 

 India, its occurrence on the western shores of that country may not be unworthy of record in 

 your pages. Yours etc., Walden.
