Spots large and scattered: ventrals cut square at their posterior margin: valves of the nostrils separate, not reaching to the mouth.

Length

From two to three feet. According to Blainville, it attains to a larger size than the last species.

Description

(Form). Closely resembling the S. Canicula, but differing essentially in the structure of the lobes of the nostrils, and in the form of the ventrals: the former are not united as in that species, and of a smaller size, leaving the whole of the mouth and the upper lip visible: the ventrals, instead of being cut obliquely, are cut nearly square, their posterior margins meeting at a very obtuse angle; they are united or separate, according to the sex, in a similar manner: the snout is rather more elongated; and, according to some authors, the tail rather shorter, giving the dorsal a more backward position, but this last character I have not noticed myself. {Colours). Upper parts brownish gray, with very little-of the red tinge observable in the last species: back, flanks, and tail, sparingly marked with large brown spots of a deep brown or black colour: under parts whitish.

Whether this species be common on our coasts or not, I am ignorant. In many instances it appears to have been confounded with the last. The only specimens I have seen were obtained at Weymouth. According to Blainville, resides amongst rocks. Skin very rough, and said to be of more value in the arts than that of the S. Canicula. In some of its characters it appears to resemble the Catulus maximus of Willughby, to which I have annexed a reference above.

Faun. Ital. Fasc. viii. Squalus melastomus, Blainv. Faun. Franc,, p. 75.

A drawing of a third British species of this sub-genus, supposed to be the S. melanostomum of the Prince of Musignano, has been recently forwarded to Mr. Yarrell by Mr. Couch of Cornwall. It was taken upon that coast. Not possessing any description of it, and not being able to speak with certainty as to its identity with the above species, I have confined myself to giving this notice of its existence in the British seas. The following are the characters given to the S. melanostomum in the " Fauna Italica." - " Sc. rufocinereus; maculis magnis obscurioribus oblongis; pinnis ventralibus oblique truncatis; ore intus nigro-cceruleo".
