Number of molars in each row of lower jaw variable, but usually 9 on 
each side, those of the inner row increasing in size to the last, or to the 
penultimate, which sometimes exceeds the last in size. Teeth of outer 
row also increasing in size posteriorly, but to a less extent and less recu- 
larly, so that the hinder four molars of the inner row are much larger 
than their neighbors in the outer row. The two inner rows meet at an 
-acute angle, the anterior pair in contact. 
Inner row of molars of intermaxillaries consisting of 21 teeth, of which 
6-7 form a row on each side, and increase in size to the hindermost or 
the one in front of it, while the remainder form a curved line of small 
tubercular teeth of even size along the inner side of thedront of the. 
jaw, behind the band of incisors. Outer row of molars 8 in number, 
similar to those of the lower jaw. Middle row formed of more numerous. 
(about 14) and, on the whole, smaller teeth than either of the outer 
rows, increasing in size posteriorly, so that, though the anterior five or 
Six are very small, the posterior ones are about equal in size to the 
smaller teeth of the outer row. The hindmost four or five teeth of the 
inner row in all cases exceed greatly in size any teeth in the other rows.. 
Gill-rakers consisting of clusters of pin-like, slender teeth set upon 
tubercles; those of the last two pairs of branchial arches largest. The 
principal clusters of teeth are triangular, with several rows of teeth, the: 
largest behind, the other rows diminishing in length and in size of teeth 
as they succeed each other anteriorly. | 
Pharyngeal bones, upper and lower, covered with a dense cluster of 
teeth similar to those in front of the jaws. The inner row of the lower 
pharyngeals larger than those in front, which are about four in number, 
and the anterior teeth rather larger than the posterior. 
Dorsal commencing immediately over the pectoral base; first spine 
about one-fourth the length; second spine eleven-twentieths of length 
of third; fourth broken in specimen examined; fifth slightly shorter; 
and the remaining spines decreasing regularly to the twelfth, which is. 
less than half as long as the third. 
Rays of soft dorsal twice bifurcate. 
Second anal spine longer than the third and about twice as long as 
the first, which is inserted a little behind the pectoral base; rays twice 
bifureate. 
Caudal deeply and triangulately emarginate on its hinder border, the 
free portion of the central rays about one-third the length of that of 
the outer rays. Outer pair of principal rays undivided, most of the 
others four times bifurcate. 
Fifth ray of pectorals longest, fourth but little shorter, lower rays 
tapering rapidly, producing a rather narrow elongate fin; rays twice 
bifurcate. 
First soft ray of ventrals longest; rays three times bifurcate. 
Seales large, broader than long, slightly striated and scalloped on 
their engaged margin, posterior margin rounded, anterior somewhat an- 
gular, the center advancing. Scales of body subequal, operculum and.
