All the above specimens are brown-headed birds, except the 

 first, from the river Volta, which appears to have been killed 

 whilst the colour of the hood was changing from brown to black. 

 This circumstance induces Mr. Sharpe to think that P. trivirgatus 

 is in reality merely the immature stage of the smaller form of P. 

 erijthroj)terus : whether such is or is not the fact must be decided 

 by future observations, which it is to be hoped will be made by 

 those Avho may hereafter have the opportunity. — Ed.]
