In the r^atalogue of Birds Sharpe recognised C. carhonaria 

 Sharpe as a larger race from New Guinea and the western 

 islands (wing 6 ins. =152 mm.), and C. assimiiis Gray, a 

 smaller race from the Aru Islands (wing 5"3-5"6 ins. = 134- 

 141 mm.). 



Among the birds from the western islands there is a 

 specimen from Waigiu in which the wing is 162 mm., while 

 that of the largest female from Misol attains 152 mm. 



From the measurements given below it will be seen that 

 though the birds from the Aru Islands are, on the average, 

 slightly smaller than those from the mainland of New Guinea, 

 and still more so than birds inhabiting the western islands of 

 Waigiu, Misol, etc., they completely intergrade. I have 

 therefore placed the southern New Guinea birds under the 

 name D. assimiiis Gray which has priority. I see no 

 object in regarding this Drongo as a subspecies of D. hracteatvs 

 Gould from Australia : the differences seem well marked and 

 of specific value.
