of the eye. The caudal peduncle is nearly as high as long. The second dorsal spine is 

 the longest, and is | the length of the head ; from it they decrease in length to the fifth, 

 the rest subequal. The second anal spine is longer than the third. Pectorals f the length of 

 the head. Ventrals do not quite reach the anal. Caudal deeply forked. Light, with indistinct 

 dark vertical streaks. Length of specimen, 73 mm. 



Fishes of this genus commonly ascend estuaries into fresh water. A fresh-water pool, 

 surrounded by mangroves, in the centre of Landu, Miladumadulu Atoll.

3. Miigil coeruleomaculatus, Lacep. 



Fishes of this genus commonly ascend tidal rivers, and a few, but not those of this

5. Chanos salmoneus, Bl. Schn.

6. Chanos gardineri, n. sp. 



D. 14, A. 9; P. 16, V. 11; Sc. 70— 75ii. 



Depth of body 4f times in the total length, length of head 3J times. Snout shorter 

 than the eye, the diameter of which is equal to the interorbital width, and is contained 

 31 times in the length of the head. The scales are enlarged on the back just behind the 

 head, and on the abdomen. Dorsal highest in front, the longest ray | the length of the head, 

 margin concave, two rows of scales at the base. Pectorals rounded, more than ^ the length of 

 the head. Ventrals rounded, arising beneath the posterior ^ of the base of the dorsal. Anal 

 scaly at the base, margin concave. Caudal deeply forked, its longest ray equal to the length 

 of the head. Caudal peduncle twice as long as high. 



The colour is probably similar to that of Chanos salmoneus, but owing to preservation 

 of the specimens in formalin this cannot be certainly stated.
