The animal kingdom, arranged after its organization : forming a natural history of animals, and an introduction to comparative anatomy . with black feet, and which is only an occasionalstraggler in the British seas. All these are, for the most part, rock-builders. Fiir- ics—sttrnum nf Gull. Others, the Xema of Leach, have a black hood in summer, like the Terns, and are generally slighter-made,breeding chiefly in marshes. The commonest in Britain is known as the Hooded Gull (L. ridiburtdus:), with thehead and upper neck brownish-black during the breeding season, and bill and legs bright vermilion : the MaskedGull (L. rapisfratiis) is rather smaller, with the hood considerably reduced, and is not common : L. atricilla islarger than either, with a stouter bill, and black legs ; also very rare: L. Sabini, smaller than the Masked Gull,is at once distinguished by its forked tail, and is met with occasionally ni Ireland and the west of Britain: andL. miiiutus, the smallest of all, not exceeding ten inches in length, and equally uncommon upon the British shores,is known by its size. There are many more, of both divisions.] S. 258 AVES. From tlie Gulls have been very properly separated Till? St-TTia (Tout The Skuas {Lestris, Illiger),—The membranous nostrils of which, larger than in the preceding, open nearer to the point and edge ofthe beak; the tail also is pointed, [and they have great coeca]. They eagerly pursue the smallerGulls to rob them of their food, and, as has been said, to devour their excrement; [the truth being,that they cause them to disgorge, whereupon they seize the food before it reaches the water, beingendowed with uncommon power of flight] : hence their name, [Lesf)-is, or robber. Four species occur on the British shores, successively smaller, with the middle tail-feathers prolonged in thesame ratio. Tlie largest (i. cataractes), nearly the size of the Great Black-backed Gull, has deep brown plumage,with the middle tail-feathers but slightly elongated
