Oberholser^^ argues that Stoporala Blyth, 1845 (type Muscicapa 

 ■melanops Vigors) is not preoccupied by StopcvroJa Blyth, 1836 (type 

 Stoparola luctuosa—Muscicapa atricapilla Linnaeus), but as it seems 

 that the one-letter rule has not been universally adopted or con- 

 sistently used even by those who have evoked it to make some 

 change, it would be better to continue to use a name of certain 

 application, in this case Eumyids Cabanis. 



The above series measures as follows : 



Family CAMPEPHAGIDAE. 



CTJCKOO-SHRIKES. 

 147. GKAUCALUS BICOLOR (Temminck). 



One male, Kwandang, October 7, 1914; one male, Likoepang, Feb- 

 ruary 28, 1916; one female, Tamboe, June 13, 1917; one male and 

 <one female, Pinedapa, February 7 and 21, 1918. 



The male taken at Pinedapa, February 21, differs from the Likoe- 

 pang male in having the feathers of the chest narrowly edged with 

 black, forming a poorly defined band ; it appears to be adult. 



Aside from the larger size and presence of white at the extreme 

 base of the tail-feathers, the bills in the above species are bluish- 

 slate, lighter at the tip as a rule, especially in the female, as con- 

 trasted with the dull black (in the skin) bills in both sexes of 

 Grcmcalus leucopygius. The specimen from Tamboe has the whole 

 culmen horn color. 



Bill slaty-blue, lighter at the tip and along the edges of the mandibles— 

 H. C. R.
