Body octangular anteriorly: snout short; much narrower, vertically, than the head: dorsal and vent nearly in the middle of the entire length.

{Form). Readily distinguished from both the foregoing species by the want of the pectoral and anal fins. Form slender, and very much elongated: body compressed, with an acute dorsal and abdominal ridge; also with three slight ridges on each side; hence the trunk from the gills to the vent is octangular; the tail is obsoletely quadrangular, becoming almost round towards the tip, which is extremely tapering: transverse shields or plates, between the gills and the vent, twenty-eight in number; from the vent to the extremity of the tail, sixty or more (Montagu says about sixty-six), but, from the extreme minuteness of the last few, not admitting of being counted with exactness: head not more than one-twelfth of the entire length; without any elevated ridge on the occiput: snout narrower than the head, similar in shape to that of S. Acus, but much shorter in relation to the entire length of the fish: dorsal occupying nearly a middle position in the entire length; the distance from the last ray to the end of the tail at the same time a little exceeding that from the end of the snout to the commencement of the fin: vent a very little before the middle, being nearly in a vertical line with the commencement of the last quarter of the dorsal fin: tail compressed at the extremity, showing a very small rudimentary caudal fin; the rays however so obsolete, and so much enveloped in the common skin, as to be scarcely distinguishable.

D. about 10; A. 0; CO?; P.O.

{Colours). "Yellowish, with transverse pale lines, with dark margins, one in each joint, and another down the middle of each plate, giving it the appearance of possessing double the number of joints it really has: these markings, however, cease just beyond the vent." Mont.

This species, which had been previously observed by Sibbald in the Frith of Forth, was obtained by Montagu at Salcomb, in 1807. A second specimen, he mentions, was afterwards picked up on the same coast. That from which the above description was taken was procured in Berwick Bay by Dr. Johnston: it is now in the collection of W. Yarrell, Esq.
