MR. H. SAUNDERS ON THE LARIN^i.

Messrs. Sclater and Salvin (P. Z. S. 1871, p. 577) quote Bur- 

 meister as an authority for the occurrence of this species near Mendoza 

 in the Argentine Republic ; but the deseription which he gives 

 clearly applies to L. maculipennis ; indeed the dimensions cited 

 being smaller than those of his L. maculipennis, Licht. (which, 

 again, is not that species, but L. cirrhocephalus, Vieill.), show 

 clearly that his bird cannot possibly be the real L. serranus, which 

 is the largest of the group of the true Hooded Gulls in America. 

 On the other hand, the dimensions assigned by Peale and Cassin to 

 their respective X. cirrhocephalum and L. ylaucotis (18 inches long), 

 and the descriptions of the markings of the primaries, go to prove that 

 those names must be referred to this species. The figure (p. 196) 

 shows the pattern of the primaries in an adult and tolerably old bird.
