Gould's specimens has the fourth tail feather tipped with white show- 

 ing that this character does not always hold. 



Piezorhynchus leucotis (Gould), Rockingham Bay, Australia. 

 Piezorhynchus chrysomelas (Gin.), New Ireland. 

 Mornarcha melanopsis (Vieill.), N. S. Wales andPt. Essington. 



Gould collection. 

 Monarcha inornatus (Gaim.), Amboina, Moluccas. 

 Pomarea nigra (Sparrm.), Tahiti. Society Islands. 



A line series, representing the supposed adult sexes and young 

 in various plumages. As the sex has not been marked on the 

 labels I cannot say whether Mr. Sharpe was correct in considering 

 the white-backed bird as the adult female. 

 Stoparola indigo (Horsf), Java and Timor. 

 Stoparola albicaudata (Jerd.), India. 

 Stoparola melanops (Vig.), India. 



One female specimen exhibits the black marks which character- 

 ized Mr. Gray's N. spilonota. 

 Stoparola thalassinoides (Cab.). 



Specimens from Sumatra which apparently belong to this species 

 have no black before the eye. 

 Stoparola panayensis (Sharpe) ? 



A female collected by Capt. Boys comes very close to this 

 species. It has a black Hue in front of the eye but otherwise agrees 

 very well with the description. I can not be certain of its identity 

 without comparison of specimens. 

 Siphia hyacintha (Temm.), Timor. 

 Siphia rubeculoides (Vig.), India. 

 Siphia elegans (Temm.), Borneo and Sumatra. 

 Siphia tickelliae (Blyth) ? 



One specimen referred doubtfully to this species. 

 Siphia banyumas (Horsf), Java. 

 Siphia philippinensis (Sharpe), Luzon. 

 Siphia turcosa (Briigg.). One specimen without locality, appears 



to be this species. 

 Digenia solitaria (Mull.), Sumatra.

 Niltava grandis (Blyth), Himalayas. 



Cassinia fraseri (Strickl), Muni River, W. Africa. Du Chaillu.
