 colour, and can exist in muddy holes without any

 spawn is very large, considering the size of the

From the drawings, it is difficult to discover 

 whether the mailing of these fish have been smooth 

 or rough ; in this, the markings lead us to believe 

 that it has been rough, particularly on the head ; and 

 the first ray of the pectoral fin seems to have been 

 spined or serrated near the tip. The mouth of this 

 species is terminal, but the upper jaw projects and
