" The knob, or caruncle over the nostrils, was not seen rounded in 

 the form figured by MM. Lesson and Garnot, in the Zoological Atlas 

 to the Voyage of the Coquille, PI. XLI, but more in the form of the 

 outline below the description of G. aurorce, which was sketched from 

 a living specimen." 



According to Dr. Pickering, this species was common in the Islands 

 of Tutuila, Upolu, and Savai, of the Samoan or Navigator Group. 



The knob at the base of the bill in this bird is not so greatly de- 

 veloped as in some other species, at least this is the case in the speci- 

 mens now before us, from the collection of the Expedition. This 

 appendage occurs in several species of the group of fruit-eating Pigeons, 

 and is, we suspect, not only peculiar to, or largest in the male bird, 

 but also most observable at the commencement of the season of incu- 

 bation, like the appendages on the head and neck, or wattles, of the 

 turkey. 



The adult male of this species is represented in our plate rather 

 smaller than the natural size.
