rows in each jaw, those of the upper jaw being smaller and less 
numerous than those of the lower. The teeth in the upper jaw 
are in two series: the outer series consists of two or three rows of 
teeth larger anteriorly but becoming smaller laterally ; the inner 
(posterior) series forms a cluster of smaller teeth several rows deep 
but not spreading laterally. In the lower jaw there are broad 
bands of teeth several rows thick which continue to the angle of 
the mouth in almost equal thickness; the outer ones of this set 
are slightly larger than those behind. 
The gill openings are lateral and they do not continue forward 
beneath. The isthmus is broad, the width being contained three 
times in the length of the head. Pseudobranchiae are present. 
There are two dorsal fins, entirely separated from each other, 
the first one has six spines and the second has ten rays; the 
anterior end of the first dorsal is considerably behind the base of 
the pectoral fin, the third to fifth spines are the longest but they do 
not reach beyond the third ray of the second dorsal fin when lying 
horizontal. The second dorsal fin begins a little forward of the tip 
of the pectoral fin; the posterior rays of this fin are slightly longer 
than the anterior ones and the last of these rays almost reaches 
the base of the caudal fin. 
The anal fin has nine rays the first of which is undivided; it 
is inserted a little behind the origin of the second dorsal fin and 
is somewhat similar in shape to that fin. Its posterior rays are 
longer and are long enough to reach some of the rays of the caudal 
fin that are attached to the ventral side of the base of that fin. 
Six specimens—one type and five co-types—have the dorsal 
and anal fin rays as follows :—

The pectoral fin has sixteen rays, some of which are thin and 
silky ; the fin is somewhat low down, rather broad, and has a round- 
ed margin. 
The tip of the united ventral fin reaches the vent. The anal 
papilla is prominent, long and muscular. The caudal fin is broadly 
rounded. 
The scales are small and are mostly ctenoid, except a few very 
small scales embedded in the occipital region of the head which is 
otherwise naked; the isthmus and chest are also scaleless. There 
are a few embedded scales in front of the vent and the part of 
the abdomen above the joined-ventral fin is scaleless. The number 
of scales in the lateral line is thirty-seven and in the lateral trans- 
verse fourteen.
