Length of fish without caudal 48 Height at the shoulder 14 Head, length 16 ; thickness nearly 8 Eye, diameter 5-5 Dorsal fin, length of base 26 Pectorals, length 14 ; distance of root from snout 17 Ventrals, length 15 Anal, length of base 11 Caudal, length 19 Family SCOPELID-E. 2. SCOPELUS LANGERHANSI, sp. n. 1st D. 12. 2nd D. rudimentary. P. ca. 14. V. 8. A. ca.24. B. M. 5 ? Compressed, elongate ; height to length without caudal fin 1 to Colour blackish, with numerous small silvery spots : two longitudinal rows of about 8 each on the belly; a row more widely separated halfway between the median line of the belly and the lateral line; a few just below the lateral line and a close row of about 20 at each side of the anal fin up to the base of the caudal. Head large; compared with length of fish without caudal as 1 to 3f. Profile quadratic ; snout very short, about half the diameter of the eye, which is round and large, being nearly 11 m m . in diameter or about one third the length of the head. It is surrounded by a thin bony crest, which is more prominent above. The space between the eyes is concave, and at the fore part of it there is a thin bony crest along the snout. The inside of the mouth and gill-covers is black. The rictus reaches to about the vertical of the posterior part of the orbit. The upper border of the mouth is formed entirely of the premaxillaries. Both premaxillary and maxillary are dilated posteriorly. Minute teeth in narrow brush-like bands are found in both jaws and on the palatines ; the innermost teeth are rather larger. There are also teeth on the vomer, and the cntopterygoids are roughened with asperities. The tongue is of peculiar form, being boat-shaped, hollowed at the middle, with a small tip. The gill-covers are scaly; the fore edge of the preopercle is turned up so as to form a thin vertical crest, which is continued nearly up to the angle of the mouth. The inner edges of the mandibular pieces are also turned up into crests. The first dorsal fin commences over the root of the pectorals and much in advance of the root of the ventrals; its base is only 16 mm. long; it does not extend quite so far as the end of the anal.
