Body veiy deep, deeper than the length of the head, and broadest at the 

 hue connecting the origin of the second dorsal and that of the anal. Snout 

 short. Small scales are found in the corselet, lateral line, and round the base 

 of the fins. They are, however, chiefly concealed under the skin, so that the 

 Ixxly seems to be entirely naked. Teeth in jaws sliarp, elongated, 16-19 in 

 the upper, and 13-15 in the lower jaw. Tillous teeth ou the vomer, palatines, 

 and the tongue. Two gill-rakers are found ou the S(K»ud branchial arch. 

 The Literal line rans nearly parallel to the dorsal outline of the body, with 

 sh'ght undulations. Many branches on both sides of the anterior ha,lf of the 

 lateral line are quite similar to those found in C. gvtkditm. The ventrals 

 are very small, Init the other fins are well developed, especially the second 

 dorsal, anal, and caudal. Intestine very long, bent more than four times. 

 Short blind process at the end of the slender pj-lorus. Air-bl«tdder wanting. 

 Abdominal cavity very low, compared with thut of other seei-fishes. Tlie 

 inner wall of the stomach has about 15 longitudinal folds. Fom- pyloric tubes 

 from the duodenum, of which the second is the longest. 



Occipital crest very high, gradually ascending Viehind. Hyoid Ixines, 

 clavicle, and hj'pocoracoid very broad. One auxiliary intermuscular lione in 

 the occipital region. In some caudiil vertebrae we fiud a lateral median groove 

 on each side, so that their cross-section is more or less octo-radiate.

 greyish blue, and the belly silvery. There are three or more longitudinal rows
