Howard Saunders has given plates of the first three primaries of L. melanocephalus and L. ridibundus, both being from birds of the year shot about March, in his paper on the Larinae, published in the 'Proceedings of the Zoological Society' for the year 1878. LITTLE GULL. Larus minutus, Pallas. French, "Mouette pygmée."
In younger birds, however, the primaries are a little more alike, but the first primary of L. melanocephalus is black or nearly so; in this state Mr.
Not at all dreaded by the natives; venomous, but not deadly, the bite merely producing a bad ulcer for a day or two. ELAPS MELANOCEPHALUS. Native name WERR. Dirty olive green on the back, from the neck to the tail; scuta 147, dirty reddish orange; head black from the nose to neck; sides of the head white; tongue forked. Doubtful if poisonous; little dreaded by the natives.
As it is just possible that the Mediterranean Black-headed Gull, Larus melanocephalus, may occur in the Islands, as it does so in France as far as Bordeaux, and has once certainly extended its wanderings as far as the British Islands, it may be worth while to point out the principal distinctions.

Blyth informs me that the females of Oriolus melanocephalus and of some allied species, when sufficiently mature to breed, differ considerably in plumage from the adult males; but after the second or third moults they differ only in their beaks having a slight greenish tinge. So again the female Falco peregrinus acquires her blue plumage more slowly than the male. Mr.
In the adult bird the head of L. melanocephalus in the breeding-season is black, not brown as in L. ridibundus, and the first three primaries are white with the exception of a narrow streak of black on the outer web of the first, and not white with a black margin as in L. ridibundus.
