(In onr former writings we accepted [Nob. Zool. 1901. p. 185; 1903. p. 5] 

 for this cuckoo the name insperatus of Gould. That bird, however, is described 

 as blue-grey above, and it came from Australia, where the present form has not 

 been found. Dr. Finsch used the name dumetorum of Gould, but the same 

 objections as to insperatus are to be made to the term dumetorum : it is described 

 as blue-grey above, and occurs in New South Wales. Neither of the two names 

 can therefore be accepted for a bird which is above olive-brown with a bronzy gloss 

 which does not come from New South Wales. The nomenclatures of Shelley and 

 Finsch are thus erroneous, and we must follow Salvadori, who accepted the next 

 early name — assimilis of Gray.) 



Ouadus assimilis Gray, P.Z.S. 1858. pp. 184, 195 (Aru Islands). 



Cacomantis infaustus Cabanis and Heine, Mus. Hein. iv. p. 23(1802 : Mysol. Finsch [Notes Leyilen 



Museum xxii. p. 81] accepts the name infaustus for the bird correctly to be called castaneiventris ; 



the description, however, does not fit castaneiventris, but an immature assimilis).
