2 Said to be a passeriform bird with four notches in the posterior border of 

 the sternum; of uncertain affinity. Hebe Shufeldt 1913, is preoccupied by 

 Hebe Risso 1826 (applied to a genus of crustaceans) so that should the form here 

 under consideration be definitely identified it may require a new generic 

 appellation. There is no necessity for action at this time in view of its uncer- 

 tain relationships. 



3 From data furnished by Dr. M. R. Thorpe of the Feabody Museum, Yale 

 University. 



^ J. D. Dana, Amer. Journ. Sci., ser. 5, XII, July, 1926, 3, 4, considers the 

 avian affinity of this supposed species as not definitely certain.
