348 Mr. Vigors*s Sketches in Ornithology. 



feared, is lost to science ; Mr. Children, who was so kind as to forward 

 my inquiries upon the subject with his usual readiness, having assured 

 me that he has been unable to discover any trace of it since he undertook 

 the superintendance of the ornithological department in the British Mu- 

 seum. This species has since been rejected by M. Temminck, certainly, 

 as I think, on insufficient grounds. But on this point I shall say more 

 hereafter. A third species has been added to the two already mentioned by 

 the scientifick acumen of Sir Stamford Raffles, who, in his description of 

 the Tetrao ocellatus among the* Birds of Sumatra, clearly pointed out 

 the affinity of that species to the well-known Rouloul. Two additional 

 species may now be given from the collection of the same distinguished 

 individual ; species which he would himself have introduced to our know- 

 ledge, had not his untimely end left to weaker hands the accomplishment 

 of these, and of many still higher objects of science. 



Of these five species, four of which are now before me, I shall pro- 

 ceed to give the specifick descriptions, as well as the characters of the 

 genus.
