the height of body; lobes of the caudal equal; the tbird anal spine much 
longer and stronger than the fourth, one fifth of the total length ; pec- 
torals shorter than ventrals. Red, with lighter longitudinal bands : a 
small brownish speck behind the first dorsal spine.

The form of the body is rather elongate, the snout of raoderate length, 
four-fifths of the diameter of eye (différence from H. laticeps). The in- 
terspace between the eyes is nearly equally broad behind and in front, 
but with a slight concavity above the middle of the eye. The two bony 
ridges are distant from one another and parallel; the groove for the 
processes of the intermaxillary bones goes not very far behind, its length 
being the same as that of the snout. The turbinai boue terminâtes in 
front in an obtuse point, scarcely covering the intermaxillary. The mouth 
is smaller than in most of the otlier species, the upper maxillary reaching 
to below the anterior third of the eye only. The diameter of the eye 
forms nearly one-third of the length of the head (opercular spine always 
included). — Ail the opercles are striated and denticulated, as the sca- 
pular and humerai bones. The praeoperculum lias a short spine, rather 
longer than one-third of the posterior margin of this bone ; the margin 
is vertical. — The dorsal spines are moderately thick; the spinous and 
soft dorsal fins are equal in height, one-half of the depth of the body. 
The lobes of the caudal are equal, pointed, and 5| in the total length. 
The first spine of the anal fin is minute; the second shorter than the 
shortest of the dorsal; the third longest, even longer than the rays, one 
fifth of the total length; the fourth is strong, about the length of the 
second of the dorsal, and may be entirely hidden in a groove of the 
third. The pectorals are rather short, one-sixth of the total length, and 
reach to the sixteenth scale of the latéral line. The spine of the ventrals 
is one-third of their own length, rather slender ; the length of the longest 
ray is nearly one-fifth of the total, and the fin reaches to the level of 
the 22 h scale of the latéral line. — The scales are not striated, but 
finely serrated at the posterior margin ; one of the largest not covering 
even \ of the eye. — Red, with violet tinge on the back and silvery 
on the belly; lighter bands along the sériés of scales. The fins are now 
uniform yellowish white ; an indistinct brownish speck is still visible be- 
tween the first two dorsal spines.”
