62 Addcndicm to Mulkrs Paper on the Vocal Organs of Passerine Birds. 



Ttllogonys among the Ampelklac, in v. Tschudi's ' Fauna Peruana,' on account of the scutes 

 on the lowest part of the pes ; and for this reason I too placed Ptilogonijs in the list 

 of those Passerines, which probably lack the muscular organ of voice. After the 

 examination of Myiadestes genibarhis, Ptilogonys must be struck out from it. 



The following fresh genera with the muscular organ of voice have also been examined : 



Bupliaga Briss., B. erytlirorliyncha. 



Andropadus Sw., sp. affinis A. importuno Gray {TrlcJiophorus brachypodioides Jard. 

 Selb.), Mozamb. 



Dri/moica, spec. Mozamb. 



Cyphorhinus Cab., C. cantans Cab., Turdus Cantans L. Gm. 



Hylophilus Temm., H. thoracicus Temm. 



Mniotilta Vieill., M. mria V. 



Parula Bonap., P. amer'icana [Sylvicola americana Audubon). 



Spindalis Jard. Selb., spec. Jamaic. 



Cardinalis Bonap., spec. Colimbiensis. 



Tiaris Sw., T. lepida {Fringilla lepida Gm.). 



SporophUa Cab., spec. Jamaic.
