Scales ctenoid. 
Colours. Purplish on the body ; tips of the dorsal spines, outer 
third of dorsal and anal rays, as well as the caudal fin, white. 
Two specimens, nearly 4 inches long, in the collection, but no 
notice where they came from. I have since procured the species at 
Akyab.

the 4. baculis, H. B. 
Bocora 1nruscata, Blyth, /.c. p. 139. 
D. 10. ¥, W/o. AO 3/8. GC. 17: 
Preopercle strongly serrated, with large teeth at itsangle. A spine 
directed backwards, apparently on the subopercle. A long spine on 
the opercle. 
Preorbital entire. Lower jaw the longest. 
Teeth. In the jaws, villiform. 
#ins. Second anal spine the longest. 
Scales. None visible now. 
Colours. Brownish-black, except the fins, which are of a dirty 
yellowish-white. 
The specimen is half an inch long and in a very bad condition. 
The occiput is broken across ; In fact, it is too damaged to describe 
from. One thing is evident, that it does not belong to the genus 
Ambassis ; it may be the fry of a species of Priacanthus.
