its body which, however, is proportionally less elongated. The flap of its oper- 
culum is much more developed, and directed obliquely downwards. The 
mouth is smaller; the posterior extremity of the maxillary not extending 
beyond the vertical line of the anterior rim of the eye. The first dorsal is 
higher than the second, just the reverse being observable in P. longulus. The 
tips of the ventrals reach the anterior margin of the anal fin. The caudal is 
slightly emarginate.

smal], situated near the upper surface of the head; the mouth is small, the 
lips large and fleshy. All the fins are very much developed and constitute a

of medium size. Anterior margin of the dorsal a little nearer to the snout than 
to the base of the caudal; anterior margin of the anal nearly opposite to the 
posterior margin of the dorsal. The caudal fin is deeply forked and slender. 
The insertion of the ventrals is in advance of the dorsal, but does not extend to 
the anterior margin of the anal. The pectorals are lanceolated, and do not 
reach with their extremity to the insertion of ventrals.
