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

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

 bordered with dark brown, the 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

This Gull is, according to Temminck, likely to be 

 found mucli more frequently on the Mediterranean 

 shores than the few recorded instances of its capture 

 on European ground would lead us to infer; being, 

 according to the opinion of that naturalist, frequently 

 confounded with its congeners.
