 »Iris red, bill and feet black. Native name: Sikurajo.'" 

 All adult males (27 in number) can easily be distin- 

 guished from the Malaccan J. cyanea by the under tail- 

 coverts , reaching nearly or entirely the tip of the tail- 

 feathers, or even (in several specimens) a little beyond. A 

 specimen from Deli (Eastern Sumatra) has the under tail- 

 coverts much shorter and may be considered a true /. 

 cyanea. I have also compared the adult males with the 

 only adult one in our Museum said to be from Java, but 

 although the label bears Temmiuck's own handwriting , I 

 hardly think that it is the specimen figured in P. C. 70. 

 On this plate the upper tail-coverts (the lower are not 

 visible) do not reach the tip of the tail-feathers, while in 

 the specimen in question they fully do so. This specimen 

 is in no way distinct from Sumatran ones and if I were 

 quite certain that it was really from Java , I should not 

 hesitate a moment to declare /. crinigera identical with 

 the Javan /. turcosa.

»Iris vermilion, bill and feet black. Native name: Sa- 

 weh itam." 



Beside an original specimen from Mr. Bock's collection , 

 our Museum was already in possession of a fine adult spe- 

 cimen of this species , collected by S. Muller in the High- 

 lands of Padang, which stood in the collection under the 

 name of Edolius carhonarius. Mi". Ramsay , in his above 

 cited original description , compares this species with Ch.
