the total length. . ... The dorsal is considerably produced at the sixth ray, which passes

The height of the body equals the length of the head, and is contained thrice and 
two-fifths in the total (without caudal); the width of the interorbital space is two- 
thirds of the length of the snout. Teeth in both jaws in two series, the outer series of 
the upper jaw being formed by very obtuse and partly confluent teeth. The maxillary 
is dilated and rounded behind, and bent upwards into a sort of hook; the barbels 
extend to the vertical from the root of the pectoral. The third and fourth dorsal 
spines are subequal in length, longer than the second, and nearly three-fourths of the 
length of the head. Greenish olive above, each scale above and below the lateral line 
with a large pearl-coloured spot; sides yellow; a rose-coloured band on each side of the 
belly. A large blackish blotch on the lateral line, behind the hind part of the spinous 
dorsal fin. A second smaller blackish spot behind the orbit; the latter is sometimes 
very indistinct. 
Two specimens, 8} inches long, were collected by Messrs. Dow and Salvin on the 
Pacific coast of Panama. 
This species would belong to the division which has been called Mullotdes.

This species, which belongs to Bleeker’s division Upeneus, is described thus :— 
D. 8)5. A. 7.- L. lat. 30. LL. transv, 22/5. 
The greatest height is contained four times in the length to the end of the median 
caudal rays, and four times and a half in the total. The head equals the height, and is 
itself longer than high, the profile in front of the eyes rapidly declines downwards, and 
is nearly rectilinear. The diameter of the eye enters thrice and a half in the head’s 
length, and the height of the preorbitar twice and three-fourths, The supramaxillar 
ends at the vertical from the front of the eye. The teeth in front of the upper jaw are 
biserial ; below uniserial. The first dorsal fin is highest at the third spine, and there 
equals the head in front of the preopercular margin; the first is exceedingly short, and 
the second and fourth nearly equal, little shorter than the third; all the spines are very 
slender towards the ends, The distance of the second from the first dorsal enters once
