17 



shagreen-like tubercles ; dorsal fin, commencing above gill cover, extends the 

 whole length of the body, colour a sort of brick red ; ventral fin absent. Tail 

 slightly rising off the direction of the long axis of the body. A row of small 

 spines, projecting forward, runs along the lateral line. At the junction of the 

 tail with the body, underneath, there is a small wart, and in front of it a strong 

 sharp spine, projecting forwards. The scales on the upper half of the body are 

 so disposed as to give a ribbed appearance : two rows of larger scales run from 

 the origin of each dorsal spine ray towards the lateral line. 



The teeth in the lower jaw are the larger. In the upper jaw the two central 

 teeth are largest, the next two smaller, and the two outer very small ; corner 

 teeth about the size of those in the lower jaw.
