THE CURAS?OWS. 209 



Adult Male. — Only differs from the male of C. carunculata in 

 having the swollen knob and wattles yelloiv^ instead of scarlet. 



Adult Female. — Only differs from the female of C. carunculata 

 in having the basal part of both mandibles yellow^ instead of 

 scarlet. 



nange. — Upper Amazons ; Pebas, Rio Napo, Rio Maranon, 

 Rio Ucayali, and Sarayacu. 



It seems more than probable that this species may prove to 

 be identical with C. carujiculata ; in dried skins of the latter 

 the scarlet knob and wattles are always yellow ; and, so far as I 

 am aware, living examples of C. globidosa have never been 

 brought to Europe, so that Spix is the only authority for the 

 statement that the colour of the soft parts is yellow, and he 

 may have taken his description from dried skins. The fact 

 that the females of both are identical in plumage is even 

 stronger evidence that the two forms belong to the same 

 species. Further evidence is wanted, and it is to be hoped that 

 any naturalist or sportsman visiting the Upper Amazons will en- 

 deavour to settle this point. The colours of the soft parts should 

 be noted as soon after death as possible, for they change rapidly.
