Habit. — Sea of Pinang. 



Total length : 6f inch. 



The scales are large, deciduous ; there is no crescent-shaped space 

 on the occiput, which is uniformly covered with scales, which advance 

 on the crown as far as midway between the eyes. The present nearest 

 approaches the Variety from the Red Sea, which Prof. Ehrenberg deno- 

 minated cceruleo-tceniatus ; it also resembles C. chrysozona, Kuhl and 

 Van Hasselt, apud Cuvier and Valenciennes. As the distribution of 

 colours of C. ccerulaureus is liable to considerable "variations, chrysozona 

 may turn out to be but a Variety. The description of the present was 

 drawn up from a single dead specimen, observed in the fish-bazar at 

 Pinang in 1845. The fishermen were unacquainted with the fish, and 

 had on that account put it aside.

The greatest vertical diameter is contained three times and one-third 

 in the total length. The length of the second dorsal spine is contained
