crenulated anterior margin, is J of the length of the head. The greatest 

 vertical diameter of the body is 2\ in the total length. The horizontal 

 spine in front of the first dorsal has in the young of this and of the 

 following species the point exposed ; with age it becomes entirely hid by 

 the integuments. In young individuals the length of the head is from 

 4£ to 4f in the total ; the greatest diameter of the orbit is 2f in the 

 length of the head ; the greatest vertical diameter of the body is 2f in 

 the total length. At Pinang small individuals are numerous at all 

 seasons. As all the species of the present genus are supposed by the 

 Malays of the Straits to be highly poisonous, they are not eaten, but 

 set aside among offal of fish to be used as manure.
