conspicuously shorter. Height of pointed dorsal much longer 
than head without snout, its spine terminates in a soft filament 
and is rather weak, corrugated and dentated on both sides 
and somewhat shorter than head without snout. Adipose fin 
small, its base rather shorter than that of the dorsal, about 
thrice its distance from it, situated above the middle of the 
anal. Height of anal, the hindborder of which is slightly 
concave, is less than the length of the ventrals, which extend 
to its origin. Pectorals more than 
*/, of the head, their weak spine is 
serrated on both sides, especially 
on its hindborder; nearly as long 
as that of the dorsal fin. Caudal 
deeply incised, pointed upperlobe 
the longer. Villiform teeth in the 
jaws in an arcuate band, those on 
the palate conical and pointed, forming two irregular, triangular, 
widely separate patches, the point of which is directed back- 
wards. 10 stiff, somewhat flattened gillrakers, shorter than bran- 
chial filaments. Brownish above, whitish below, fins yellowish, 
with a darkish hue. Length 225 mm.

Height 5; head 3'/,, its width about 114/, in its length. 
Headshields smooth, only the occipital part with few granules 
and rugosities. Occipital process triangular and about as long 
as broad or a little longer than broad at its base. Its hind- 
border is totally united with the crescent-shaped basal bone 
of the dorsal spine, the ends of which are prolonged. The 
superficial median fontanel begins on the snout and ends in 
a point at the base of the occipital process. Eyes 8—9, situated 
in the anterior third of the head, 3'/, times in the convex 
interorbital space. The broad snout is rounded, its anterior 
margin arcuate, its length a little more than '/, of the head.
