 ' Catalogue of Birds.'

 digitoriim as in Buccones ; wing-coverts Oscinine ; caudal muscles peculiar, as also the 

 terminal caudal vertebrae (c/. Stejueger, t. c. p. 415) ; spinal feather-tract well defined 

 on the neck, and forked on the lower (not the upper) back ; postscapular feather-tracts
