Lord Walden on a new Species of Triohostoma. 377 



ding page he had already shortly described a Bonieau bird, 

 which, with some doubt, he identified as being the true Na- 

 pothera umbratiUs, Teram. (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 Temmiuck's MS. title already cited. Ever since it has 

 been a matter of great dilSculty 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 differs 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 suffi- 

 ciently well with 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. Gl). 



Since then I have received from North Celebes several 

 examples of a species of Trichostoma widely diff'ering 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 differs 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 the Macassar bird, supplied the type of T. celebense, 

 Strickl. : consequently the Macassar form requires to be dis- 

 tinguished by a separate title ; and for it I propose that of
