Adult. Differs from C. innominata chiefly in its much smaller 

 size ; the hand across the rump is dusky yvhite or smoky grey with 

 darker shafts ; the tarsi seem to he always unfeathered, except in 

 some specimens from the Malay Peninsula, which differ mxich from 

 the form from the islands in the Pacific Ocean. Total length over 

 4 inches, wing 4-4 to 4-5, tail 2'1. 



JFah. Fiji, Samoa, Friendly, and Solomon Islands, Ternate, New 

 Guinea and Northern Australia, and Mauritius and Bourbon. 



It is often stated to inhabit Madagascar, but I do not know 

 whether specimens have been actually obtained in that island. 

 Slightly differentiated forms are found in Tenasscrim and the Malay 

 Peninsula, and the islands off the West coast of the Malay Peninsula 

 to South Andaman, 



This species has an enormous distribution, and forms several local 

 races like its congener C. fuciphacia. The large birds from the 

 Mergui Archipelago cannot be mistaken and may safely be re- 

 garded as a species, G. innominata of Hume. The birds from Fiji, 

 Samoa, Friendly Islands, Solomon Islands, and Ternate are very 

 dark and the back has very little gloss. The colour of the back in 

 specimens from Australia (i. e. C. terrce regime of Ramsay) is a little 

 paler, hut those from Mauritius and Bourbon are perfectly similar. 

 Specimens from Mergui are paler beneath, and the feathers of the 

 lower surface and of the light grey band across the rump have more 

 obvious dark shaft-stripes. The specimens from South Andaman 

 and Selangore (Klang) in the Malay Peninsula have the light band 

 across the rump, which is dusky whitish or pale dusky grey in the 

 typical forms, ill-defined, often so faint, that they nearly approach 



* A typical specimen, kindly lent me by tbe author, does not differ from many 

 examples of the dark Pacific form in the collection.
