rays, towards the middle, equal the length of the gill-opening ; the 

 base is sloping, and equals the distance between the chin and the first 

 dorsal spine. The interval between the last dorsal and root of the 

 upper caudal ray is contained 2\ times in the extent of the posterior 

 dorsal fin, it equals the vertical diameter of the root of the caudal, 

 but it is \ of the length of the latter. The anal commences a little 

 in front of the posterior dorsal, and terminates a little farther back. 

 In very young individuals the caudal is bluntly pointed, \ of the 

 total length ; in older ones it becomes rounded, and scarcely exceeds \ 

 of the total. The rounded pectorals commence behind the lower hall 

 of the gill-opening, which latter they scarcely exceed in length. The 

 greatest vertical diameter of the body, at the first dorsal spine, is \ of 

 the total length ; that at the first ray of the posterior dorsal is less by 

 \. Four solitary individuals were at considerable intervals observed 

 at Pinang. Shortly after death the spots of the body almost entirely 

 disappear, and specimens preserved in spirits of wine acquire a pale 

 dark slate-colour. They might be mistaken for Alutarius herardi, 

 Lesson,* but the latter species is distinguished by a proportionally 

 shorter head, a smaller eye ; the anal fin commences a little behind 

 the posterior dorsal, and the distance between the latter and the caudal 

 equals the length of the caudal, and is consequently proportionally 

 greater.
