 2. Sub-genus (?), LANIELLUS.

Type. — Lanius leucogrammicus, Reinwardt. 

 Obs. — I suspect this may prove to be the rasorial type of the restricted genus Lanius ; the nostrils, in fact, are quite 

 those of a rasorial bird. 



* The characters of other genera or sub-genera, which we have denned in zoological periodicals, will be found collected 

 in the ornithological portion of the " Encyclopaedia of Zoology," now almost ready for the press.
