Haploophone,'" catacromyodous,'' heteromerous « Mesomyodian 

 Passeres with the tarsal envelope pycnaspidean,-'^ holaspidean^ or 

 modified taxaspidean ^ (never exaspidean ^) , first (basal) phalanx 

 of middle toe never wholly united to inner toe, nor second phalanx 



'^ Two specimens. 



b One specimen. 



c Having the syrinx simply broncho-tracheal (typically Passerine). See Garrod,

 Gadow, Bronn's Thier-Reich, Vogel, ii, 1893. 



« The main artery of the thigh is the femoral instead of the sciatic; in this respect 

 agreeing with the Pipridse, all other Mesomyodi (including Rtipicola) having the 

 sciatic artery developed instead of thc^ femoral.
