At the time when our notes on the genus Asturina published in the Zoological Society's 

 "Proceedings' 7 for 1869 were written, we were not perfectly certain whether Schlegel's Asturina 

 gularis in the Leyden Museum was referable to the present bird. Soon afterwards, our 

 artist, Mr. Smit, being in Leyden, we requested him to make a coloured drawing of Schlegel's 

 type-specimen, which, by the kindness of the authorities of that celebrated institution, he was 

 permitted to do. Upon his return to this country with the drawing we had no difficulty in 

 recognizing in it the adult dress of Asturina pucherani. 



Of the three other species belonging to the present section this Asturina appears to resemble 

 most nearly the northern A, rufaauda, having the tail-bands rufous instead of pale cinereous. 

 But it is immediately distinguishable in the adult dress by its dark throat (from which, no doubt, 

 Lichtenstein derived his name gularis), and by the pale ochraceous colouring of the lower 

 surface. 



There is a single adult specimen of this Hawk in the Gallery of the British Museum said 

 to have been received from Bolivia. 



Our principal figure of this species is copied from the drawing already spoken of, which 

 was made by Mr. Smit from the typical specimen of Asturina gularis in the Leyden Museum, 

 and represents it at two-thirds of the natural size. The figure in the back-ground is taken from 

 the typical specimen of Asturina puckerani in the Norwich Museum, which has been kindly lent 

 to us for this purpose. 



May, 1869.
