. Catalogue of seals and whales in the British Museum . Seals (Animals); Whales. 354 ZIPHIID^. the width at,the widest part of the brain-case 1 foot 6 inches; the length in a straight line, from the tip of the rostrum to the crest over the blower, 2 feet 11 inches; the height of the skull, from the hinder part of the palate to the crest over the blower, 1 foot 2 inches. Fig. a, b. Skull and lower jaw of Ziphitts Layardii. from front. c. Teeth of lower jaw, The entire length of the lower jaw 3 feet; the length from the con- dyle to the hinder edge of the base of the tooth 1 foot 11J inches; the length of the exposed part of the tooth along the anterior edge, 9| inches; the width, below the teeth, of the side of the lower jaw, measured from the inner part of their base, 3 inches. There is a partial hollow, as if it were the cavity of an old tooth that had fallen out, on the margin of the lower jaw, behind the base of the elongated arched tooth. The skull which I described from the notes of Mr. Layard and the drawing of Mr. Trimen under the name of Ziphius Layardii (see Proc. Zool. Soo. 1865, p. 358) proves on examination, as I decided from the notes and drawing, to be a very distinct species of the genus, allied to Z. micropterus. The peculiar form of the teeth (wHch are elongated and arched over the outer surface of the upper jaw, so as to prevent the animal from opening its mouth beyond a very limited extent), it has been suggested to me, may be only an individual peculiarity or a malformation. I scarcely think this is the ease; but even if it should be, it wUl not in the least militate against the distinctness of the species, as the proportion of the beak to the size of the brain-case, and the form of. the beak and position and form of the teeth (with a small point near the front edge of the tip)..
