yet conspicuously larger than the rest. The central point, the largest, 

 commences opposite the seventh dorsal spine, and terminates in a 

 blunt point opposite the fourteenth spine, while the lower, somewhat 

 undulating margin, extends to a little in front of the origin of the 

 ventral fins. Between the occiput and the anterior third of the pec- 

 toral fin, appears an oblique triangular space, covered with narrow elon- 

 gated scales, but bounded behind by 4 or 5 oblique series of large 

 rectangular scales. The lateral line commences gently ascending 

 towards the sixth dorsal spine, from whence it gently descends till 

 opposite the anterior dorsal spurious fin, when it proceeds straight to 

 the cartilaginous keel of the tail. The third point of the corslet ter- 

 minates on the abdomen, opposite the point of the pectoral fins. A 

 single individual occurred at Pinang in December 1844.
