Four or five inches.
(Form). Much more elongated than either of the preceding species: depth, which is tolerably uniform throughout, equalling not more than one-seventh of the entire length: body considerably compressed: snout short and obtuse; the profile descending in a curve: " outline of the mouth, when viewed from above, forming a semicircle; viewed laterally, the angle of the mouth is depressed," the lower jaw ascending to meet the upper: gape rather wide; " lips capable of extensive motion:" teeth small and short; rather irregularly disposed, and not all exactly of the same length: eyes high on the cheeks, hut not elevated above the crown: the intervening space flat, ornamented with four fimbriated tentaculiform appendages; the first pair of appendages are placed, one at the anterior margin of each eye, and are connected at the base by a low transverse membrane or fold of the skin; the second pair, which are twice the length of the first, and rather more fimbriated, are placed further back near the posterior margins of the eyes: " nape of the neck, and for some distance towards the commencement of the dorsal fin, the skin is smooth, with the exception of various small papillae:" orbits surrounded by a circle of large, open, conspicuous pores: a row of similar pores at the upper part of the opercle, falling in with the commencement of the lateral line: dorsal commencing in a line with the upper angle of the opercle, and extending quite to the caudal, with which it is continuous; its height, which is uniform throughout, equalling rather more than half the depth of the body; the first ray a little shorter than the second; all the rays simple, and apparently all spinous or inarticulated, their extreme tips projecting beyond the connecting membrane; the first three, however, accompanied by short filamentous prolongations of the membrane, which extend further than themselves: anal commencing in a line with the fourteenth ray of the dorsal, and extending, like that fin quite to the caudal; the first ray only half the length of the second; the second a little shorter than the third; this last and the rest nearly equal, and of ahout the same length as the dorsal fin-rays, the ends, however, projecting further, the connecting membrane not being so deep: caudal rounded, with the principal rays branched: pectorals a little shorter than the head, also rounded: ventrals very small, consisting of only three rays, the longest being scarcely more than one-third the length of the head: number of fin-rays;

(Colours). "General colour of the body and fins pale brown, mottled on the sides with darker brown; the head, the anterior part of the body, the ventral and pectoral fins, being darker than the other parts." Yarr. Of this species, I have only seen the specimen, taken at Berwick-upon-Tweed, which has been already described by Mr. Yarrell, and which was kindly lent me for examination. To that gentleman we are indebted for having cleared up some part of its history. It is probably the same as the B. Galerita of Dr. Fleming, which was found by him in Loch Broom. It is also clearly identical with Pennant's figure of the Crested Blenny, but the description of that species, in the " British Zoology," is in part borrowed from Willughby, and belongs to the Alauda cristata of that author, which last I am inclined to think is synonymous with the next species.
** Head with one principal, transverse, crest-like, appendage.
