223 R. E. Lloyd : Marketable Fish from Akyab. [Vol. I, 



ClirROCENTRID.'U. 



17. Chiroccnlnis dorab. 



This is an interesting specimen as it differs from the description 

 somewhat in its proportions : head to body, 1:6; height to length, 

 I : 6. Day gives these proport ons as : head to body, i : 6^ — y^ ; 

 height to length, i : 6^ — 9. Bleeker divides the species into two, 

 C. dorab and C. hypselosoma. The present specimen agrees with 

 his C. hypselosoma. 



" Name Nga darhay ; common in the sea throughout the year." 



NOTOPTERID^. 



18. Notoptcnis kapirat. 



This specimen resembles the iypa in having large scales on 

 the cheeks, in having 105 rays in its anal fin, and in its proportions 

 generally. It differs from the t3'pe in that the angle of the mouth 

 is behind the centre of the e^-e, the dorsal profile is more convex 

 than the ventral and there is a slight concavity in the profile of 

 the head. In these three points it approaches the tj'pe of A'', chiiala. 

 It a' so has a wide scaleless flap of sk'n attached to the margin of 

 the operc e. Such a flap is not mentioned by Day in the descrip- 

 tion of either species ; but it is figured in the case of N . chiiala 

 alone, 



"Name Nga phay ; common in rivers from February to March." 



OSTERIOPHYSI. 



SlLURID^.

 " Name Nga cray ; common in rivers and tanks." 



20. Plotosiis canius. 



Both dorsal and pectoral spines are quite smooth on the ex- 

 posed edge though serrated on the other ; otherwise the specimen 

 is typical,
