Like the Celebean forms C. grayi and C. porphyrolcemus, it has the sides of the metallic throat 

 margined with a distinct band of steel-blue, which is not met with in the other members of this 

 group ; and they also resemble each other in the absence of metallic colouring on the scapulars 

 and median series of the wing-coverts ; but this latter character is not confined to these three 

 species. 



The present bird was first described by Dr. Meyer from specimens collected by himself at 

 Siao, one of the Sangir or Sanghir Islands, a small group situated to the north of Celebes ; and 

 it appears to be exclusively confined to that archipelago. 



Count Salvadori has more recently received a large series of forty specimens obtained in the 

 island of Petta by Bruijn, which he divides into nine varieties of plumage. The first is the fully 

 adult male similar to the specimen in my own collection, which I have figured on the same Plate 

 with C. porphyrolcemus ; this specimen was collected by Duyvenbode in Siao in 1866. The next five 

 are in the gradual changes of plumage between the young and adult male, and offer nothing out 

 of the common in their mode of moult. The last three plumages mentioned are exhibited in 

 my second illustration of this species, and represent the adult female with the pale yellow throat, 

 and two plumages of the male : one I have designated " male in moult " with the throat of a 

 similar yellow to that of the female ; the other, " young male," with the orange shade on the 

 throat. It appears to me probable that these two plumages should be referred respectively, one 

 to the adult male in moult, the other to the young male prior to its first assumption of the full 

 dress ; and 1 would therefore refer the more orange throat to the younger bird. 



In this latter dress, according to Count Salvadori, were the specimens which Dr. Meyer 

 referred to the females of E. duyvenbodei ; and he further remarks :— " I do not know to what 

 cause can be attributed this orange shade on the upper part of the throat ; it is not equally 

 intense in all the specimens, from which I argue that it is a mere variation to which individuals 

 of this species are subject." 



This species differs from all the other members of this group, not only in the peculiar 

 colouring of the male, but also in the female not having the head and neck of the grey colour 

 which we find in the other species. 



I have retained Dr. Meyer's original spelling of the name, as these islands are marked upon 

 different maps as the Sangir or Sanghir Islands.
