These two species of mullet closely resemble one another, but 

 I have not been able to identif}^ either of them with any of Day's 

 species of the genus, most of which are separated by small distinc- 

 tions. The two specimens resemble one another in the following 

 features : — 



The greatest depth of the body is more than the length of the 

 head, which is '- of the total length ; the dorsal fin commences 

 half way between the end of the snout and the base of the caudal ; 

 the snout is equal to the diameter of the eye, which is half the 

 interocular distance ; the mandibles meet at an obtuse angle ; 

 both anterior and posterior e3^elids are present. 



They differ from one another in the following points : — 



One specimen, which is called " Nga man," is 8 inches long 

 and is said not to exceed this length and to be common in river and 

 sea. Its anal fin commences well in front of the second dorsal ; 

 the pectoral is as long as the head ; the head is convex from side 

 to side, and the specimen has a yellowish tint in spirit. 



The other species, which is called " Nga cangying," is said to 

 be uncommon and never to be found in the .sea ; it is also said to 

 attain a length of 14 inches. The second dorsal and the anal com- 

 mence at the same level ; the pectoral is not so long as the head, 

 whicl^ is nearlj^ flat.
