The six birds collected by Mr. Degen shew that the black 

 band across the middle of the outer tail-feathers is a variable 

 character not dependent on age or locality. 



Two adults (a and b) from the Mogre River have a more 

 or less extensive patch of yellowish green on the basal half 

 of the outer tail-feathers, terminated by a dusky border or 

 band. 



Another adult specimen (c) from the same locality has the 

 band across the basal part blackish. 



Specimen e has the band wider and blacker. 



In specimen/ the band is widest, about 0'5 inch. 



It will thus be seen that the specimens mentioned above 

 agree with the other specimens of O. monachus in the British 

 Museum Collection (cf. Ibis, 1900, p. 565, figs. 1 & 2) and 

 differ from the examples in the Turin Museum, some of 

 which have a heavy black band across the outer tail-feathers 

 about an inch and a half wide. 



Specimen d. An immature female from the Mogre River 

 has only a patch of yellowish green on the basal part of the 

 outer web of the 2nd, 3rd, and 4th pairs of tail-feathers and 

 shews no trace of a black band.
