Description of a neiv Species of the Genus Trichostoma from the Island of Celebes. By Arthur, m^ i876 

 Viscount Walden. [From ' The Ibis,' July 1876, Plate XI. in orig.] P- 376. 



In Jardine's 'Contributions to Ornithology' (1849, pp. 127, 128, t.) the late Mr. Strickland 



gave a short account, accompanied by a figure, of a Celebean bird on which he bestowed the 



title of Trichostoma celebense. On the preceding page he had already shortly described a jj^jg jg^rg 



Bornean bird, which, with some doubt, he identified as being the true Napothera umbratilis, p- 377. 



Temm. (a manuscript title). Both species were among some birds purchased by Mr. Wilson 



from M. Verreaux, and which the latter gentleman, according to Mr. Strickland, had confounded 



together, as both bore on their labels Temminck's MS. title already cited. Ever since it has 



been a matter of great difficulty in Europe to determine the species Mr. Strickland had before 



him, and which he named T. celebense — for the reason that the types of both the Bornean and 



Celebean species went to America, that the description of T. umbratile apud Strickland is very 



brief, while that of T. celebense consists of nothing more than a few words setting forth in what 



respect it difi"ers from the Bornean bird (a species not even now determined), and that the figures 



of both birds are neither drawn nor coloured satisfactorily. 



But so long as only one species of the genus Trichostoma was known to inhabit Celebes, 

 and that species agreed sufficiently well Avith Strickland's brief description, that species was, 

 naturally enough, referred to T. celebense ; and a single example, obtained at Macassar by 

 Mr. "Wallace, was thus identified by me (Tr. Z. S. viii. p. 62 f). 



Since then I have received from North Celebes several examples of a species of Trichostoma 

 widely difiering from what I supposed to be T. celebense ; and it becomes therefore necessary to 

 decide which of the two species best agrees with Strickland's account and figure of T. celebense. 

 Dr. Otto Finsch has also sent me for determination an example of this genus, marked as being 

 a male, obtained by Captain Conrad in the district of Macassar. This bird diflfers but slightly 

 from the one obtained by Mr. Wallace, now in the British Museum. After comparing the two 

 species with Strickland's description and figure, I have little doubt that the Menado, and not
