Head 3J, depth 4, eye 34 ; scales about 30 ; D. IV-I, 8 ; A. Ill, 

 9. 



Agrees in every respect with the description gven by Giinther. 



POLYNEMIDJE. 



Polydactylus tetradactylus (Shaw). 



Polynemus tetradactylus Shaw, Zool., V, 155, 1819 ; Giinther, Cat. Fishes, II, 

 329, I860; Day, Fishes of India, p. 180, 1888. 



One specimen, 7 inches long. 



Head 3£, depth 4, eye 5 ; scales 89 ; D. VIII-I, 15 ; A. Ill, 15. 



Longest rays of soft dorsal much longer than its base, all reach- 

 ing past end of fin ; longest rays of anal about equal to its base, 

 some falling short of end of fin. Pectoral filaments four, scarcely 

 reaching past base of ventrals. Upper caudal lobe slightly longer, 

 middle caudal rays less than one-third length of lobes. First dor- 

 sal spine very short, about equal to length of adjacent scales. All 

 fins, but spinous dorsal, finely scaled. Scales minutely granulose 

 and toothed, lateral line extending on to lower caudal lobe, not on 

 upper. Tail deep and compressed, its width 2 \ in depth at middle 

 point between anal and caudal. Preopercle finely serrate, the ser- 

 rse becoming slightly larger downward. Scales deciduous on oper- 

 cle, which is finely striate. Teeth on mandible even on outer side. 

 No air bladder ; very numerous small pyloric cocca. 



MULLID^I. 



Upeneoides bensasi (Sohlegel). 



Mitllus bensasi Schlegel, Fauna Japonica, p. 30, p. XI, fig. 3, 1847. 

 Upeneoides bensasi, Giinther, Cat. Fishes, I, 399, 1859; Day, Fishes of India, 

 p. 121, pi. 30, fig. 5, 1888. 



Three young specimens, 4 inches long. 



Head 3*, depth 4g, eye 3i ; scales deciduous, 25 or 30 ; D. VII, 

 9 ; A. 7, P. 14. 



Eye 1} in snout, interorbital equal to vertical diameter of eye, 

 maxillary reaching vertical from anterior margin of orbit. Vom- 

 erine teeth in two diverging oblong patches connected by a single 

 series, all other teeth in narrow bands. Barbels reaching past pre- 

 operculum, about to middle of operculum. Height of dorsal equals 

 depth of body ; origin of anal under third or fourth ray of dorsal. 

 Length of ventral equal to head without snout ; pectoral long, 

 reaching past tip of ventral, about to tip of depressed dorsal. 



One would expect to find Upeneoides tragida in this territory, but 

 the specimens more nearly agree with the above.
