Teeth in the upper jaw blunt, acicular, set side by side like the teeth of a comb, 

 about thirty-two on each side. In the lower jaw they are shorter and more slender and in 

 double rows. Villiform teeth upon the palatines, in about two series. The height of 

 the body is contained once and one-fifth in the length of the head, which is contained 

 twice and one-third in its distance from the vent. Diameter of the eye one-eighth of 

 the length of the head, and nearly one-half of that of the snout. Ventrals broad, with 

 peduncle-like bases thickly covered with scales ; closely adjacent, separated by a narrow 

 groove (Goode). 



One specimen, nearly three feet long, was taken from the stomach of a Laemargus 

 horealis on the Grand Bank of Newfoundland.

The greatest depth of the body is opposite to the ventral fin, and contained twice 

 and. two-thirds in the distance of the vent from the end of the snout; the length of 

 the compressed oblong head is contained twice and one-third in the same length. 

 The snout is thick, swollen, much produced beyond the narrow transverse mouth, which 

 is opposite to the front margin of the orbit, and quite at the lower side of the head. 

 Twenty teeth on each side of the upper jaw. The eye is close to the upper profile, 

 two-thifds of the length of the snout, one-fifth of that of the head, and less than the 

 width of the interorbital space. Gill-opening of moderate width, the gill-membranes 

 being confluent in the vertical from the upper end of the gill-opening, and not attached 



to the isthmus. 



The whole body and head are covered with minute, smooth, imbricate, and adherent 



scales. 



All the dorsal spines are short, the anterior very short, the second opposite to the 

 vent. The anal spines commence immediately behind the vent, and increase in length 

 posteriorly, passing into the flexible rays, which are of varying and indefinite number. 

 The pectoral is inserted at the usual distance from the giU-opening, and has the base of 



moderate width. Ventrals united and extending to the vent.
