Mugil sepfentrionalis, n. sp. (The Thick-lipped Grey Mullet.) Nine (rarely ten) soft rays in the anal fin; upper lip thick, with two series of short and obtuse papillae on its inferior third; the extremity of the maxillary is visible behind and below the angle of the mouth. The prseorbital is very obliquely truncated^ so that its posterior angle is pointed, whilst the anterior is very obtuse and rounded. Mandibles very broad, almost entirely covering the chin. The pectoral extends to the tenth scale of the lateral line; that is, it terminates at a considerable distance from the origin of the dorsal fin, which is above the fifteenth scale, and exactly on the middle between the snout and the base of the caudal. Mr. Couch* has the merit of having shown that, besides M. capita, a second species of Grey Mullet exists on the British coasts; and finding that it has a similarly thick lip as M. chelo from the Mediterranean, he has considered it as identical with this southern species. Both the northern and the southern thick- lipped Mullets, indeed, are very similar to each other; and it has been nearly impossible to see, or to show, their specific differ- ences otherwise than by comparison of actual specimens, as the descriptions and representations existing have taken little notice of the distinctive characters. Yarrell and Parnell have adopted Mr. Couch's determination, the latter giving an original descrip- tion f, in which, however, some of the numbers of the fin-rays are erroneous (2. D. 10, A. 11, instead of 3. , A. |); Hancock's M. britannicus is placed by him here as a synonym, whilst it is described by Hancock as having thin lips, &c. The characters by which this species differs from the southern are the following::—. Please note that these images are extracted from scanned page
