Specific Chcxracters. — Beak long and slender; wing coverts lead 

 colour; the first three primaries with their inner webs white, 

 bordered with dark brown, ths first narrowly, the others deeper, 

 the fourth entirely dusky. Length of tarsus one inch and three 

 quarters ; length sixteen inches ; carpus to tip eleven inches and 

 a half; beak two inches and a fifth; middle toe one inch and 

 one tenth. 



This Gull is, according to Temminck, likely to be 

 found much more frequently on the Mediterranean 

 shores than the few recorded instances of its capture 

 on European ground would lead ns to infer; being, 

 according to the opinion of that naturalist, frequently 

 confounded with its congeners.
