Genus SARDINIUS, W. von der March. 
[Zeitschr. deutsch. geol. Ges. vol. x. 1858, p. 245.] 
Head small and trunk moderately elongated, the maximum depth 
at the insertion of the dorsal fin. Mandibular suspensorium much 
inclined backwards, and cleft of mouth large; jaws slender, and 
maxilla not expanded behind ; teeth minute, numerous and sharply 
pointed. Gill-rakers large and slender. Vertebrae about 45 in 
number, half caudal and half abdominal; the centra at least as 
long as deep, longitudinally striated; ribs delicate. No fin-rays 
elongated, but two or three in front of the median fins undivided 
and spinous. Pectoral fins with about 18 rays, relatively large and 
inserted just above the ventral border; pelvic fins smaller, with 
about 10 rays, opposed to the dorsal fin, which is nearly median 
and comprises about 18 rays ; anal fin behind the dorsal, longer than 
deep, with 20 rays; caudal fin slightly forked. Scales large and 
uniform, pectinated and serrated, not deepened or thickened along 
the course of the lateral line.

Type. Nearly complete fish. 
The type species, attaining a length of about 0*13. Length of 
head with opercular apparatus scarcely exceeding the maximum 
depth of the trunk, and a little more than one quarter the total 
length of the fish to the base of the caudal fin. Pays of pectoral 
fin, when adpressed, nearly reaching the base of the pelvic fins, 
which are opposed to the origin of the dorsal and slightly nearer to 
the anal than to the pectorals; dorsal fin deeper than long, the 
length of its longest ray equalling the depth of the trunk at its
