opercles, except the posterior part of the opercle, and the abdomen to a 

 little in front of the anus, are spinous ; but the cheeks, lips, throat and 

 the posterior part of the body, from between the anus and dorsal, are 

 naked. A single individual was observed at Pinang in January 1844.

 indistinct and spotted like the rest, viz. one between the eyes, a second

Coromandel. 

 Total length : 7 inch. 



The head is elongated, contained 3 J times in the total length. The 

 eye is situated a little nearer the muzzle than the gill-opening, with which 

 the lower margin of the orbit is nearly on a level ; the horizontal diameter 

 of the eye is J of the length of the head ; the distance between the anterior 

 angle of the orbits equals two such diameters ; between the posterior 

 angles it is 2^. A little in front of the anterior angle of the orbit appears 

 a single small aperture, with a small simple tentacle at the anterior 

 margin. The suture of the two upper teeth is not closely fitting as in 

 the other species, but a little open so as to display 6 or 7 small denti- 

 culations on the corresponding margin of each tooth ; otherwise the 

 teeth and tongue are normal. The rounded dorsal is situated a little 

 behind the commencement of the posterior third of the body, the 

 caudal not included ; the two first rays are undivided ; the third and 

 fourth, the longest, are contained 2| times in the length of the head, of
