Mr. R. B. Sharpe on the Genus Glaucidium. 35 



Aquila bonellii one day sailing high over Vacca^ and in a short 

 ramble up a little valley near our anchorage in the Gulf of 

 San Antioco observed Circaetus g alliens, Caccabis petrosa, 

 Corvus cor ax, and a few other common birds. On Toro my 

 men found a few large fragments of spherical shell, rusty and 

 weather-eaten. 



After this delay we at length reached Port Mahon on the 

 last day of May ; and after a short stay there (during which I 

 had the good fortune to captui-e some specimens of a new lizard 

 on the Isla del Ayre) , we made the the best of our way home 

 via Iviza, Valencia, Barcelona, and Marseilles, at which port 

 we arrived June 21st. At Valencia we spent a long summer 

 day in the fragrant " dehesa," but saw no birds worthy of men- 

 tion. I succeeded in bringing home alive my Gulls, as 

 before mentioned, one of the young Ravens taken on Vacca, 

 one young Hooded Crow from near Cagliari, a Greek Par- 

 tridge [Caccabis saxatilis) which I bought at Syracuse, and 

 two Blue Rock-Thrushes. 



It seems to me, on reading over this paper, that I ought to 

 apologize for the frequent use of the first person singular and 

 plural ; and any one who can and will give me a practical 

 suggestion as to how to avoid it shall have my lasting grati- 

 tude, quantum valeat.

In the ' Proceedings ' of the Boston Society of Natural His- 

 tory for 1873, Mr. Robert Ridgway gave a review of the 

 genus Glaucidium, which has done more than any previous 

 attempt to clear up this difficult genus. Having myself had 

 occasion recently to study these birds, I found great assistance 

 from Mr. Ridgway^s paper ; but differing in many points from 

 that gentleman, I have been led to place my views before
