Six specimens , viz. two adult males and two females 

 from Muliino , collected in April , with entirely red bills , 

 and male (14 Febr.) and female (18 March) in transitional 

 stage, from the Kasinga River. In the latter male the 

 parts which are beautifully metallic green in the adult 

 bird, are blackish with a faint steelblue and purplish gloss, 

 the throat is dull brown , the bill entirely black. 



The immature female is in many points more advanced 

 towards the adult stage. It has the bill almost entirely 

 red and the metallic colors are fully assumed , but most of 

 the quills and wing-coverts are dull brown , and the tail- 

 feathers show the same color on the terminal part.

 in the males.
