* If the later ascertained locality of this form, British Guiana, is correct 

 it must be a perfectly valid species, and can have little direct relationship 

 with A. a. albigularis. 



Dr. Hartert, who examined the description of Oustalet's Astur sharpei 

 (Bull. Soc. Philom. (6), xi., p. 25, 1875) with me, thinks it is merely an example 

 of A, albigularis albigularis, and I have therefore omitted it.
