Circus rufus, Briss. 



" Shot near Lake Tajoora, December 1, 1842. Female. Had an 

 imraense ąuantity of eggs in its ovarium ; I never before met ^ith 

 so astonishing a number in any bird. Its brain was large, and, ex- 

 cepting the tubercular masses on its base, consisted of almost entirely 

 cineritious matter. Cranium strongly marked \vith protuberances 

 on its upper surface." 



Alcedo ispida, Linn. 



" Female. Shot on the sea-shore 18th of November 1842. Said 

 to be a rare bird at Tripoli. This specimen, together with others 

 I found at Trebizond, were a good deal smaller than those birds I 

 procured at Erzeroom." 



Muscicapa grisola, Linn. 



" Very common about the trees on the Jebel mountains, May and 

 June 1843." 

 Muscicapa albicollis, Temm.

 in the Owaniyeh valley on Jebel mountains, May 1843. Flies ex- 

 actly likę a swaUow."

 tal of Fezzan, March 1843."
