 Fish. India, p. 742 (.see synon.). 



Disk about twice as wide as long ; tail more than three times as 

 long as the disk. Fleshy prolongation of snout short, no horn on 

 orbit. Body with a row of small tubercles along the median line 

 of the back in the scapular region. Fins dorsal situated at the 

 commencement of the base of the tail, behind the end of the 

 insertion of the ventrals ; no spine posterior to it. Colour 

 greenish brown, with round blue spots in the posterior half of the 

 disk. /Tail white with black rings.

 Syn. Stoasodon, Cantor. 



Head distinct from disk ; snout with a soft prolongation, in- 

 tsrnally supported by fin-rays. Nasal valves usually distinct, each 

 1'orinini* a long flap, or they may be united into one quadrangular 

 flap. Teeth in a single row, hexagonal, broad, flat, with the lower 

 dental laminso projecting beyond the upper. Tail very long and 

 whip-like ; dorsal fin present near its base, and a serrated spine 

 posterior to the fin.

The comparative proportions of this fish vary greatly with age ; 

 the distance from the mouth to the anus equals about half the 

 width of the disk. Nasal valves in some examples separate, each as 

 a long flap ; in other examples the valves unite and form a quad- 

 rangular flap the lower edge of which is fringed ; the spiracle 

 wider than the orbit. Teeth broad, flat, and in a single row, 

 those in the lower jaw may be angularly bent or nearly straight ; 

 the lower dental plate projects beyond that in the upper jaw. 

 Fins the dorsal arises opposite the base or centre of the ventral, 



* MYLIOBATIS VESPERTILIO, Blecker. 



Disk at least twice as broad as long ; snout somewhat produced ; no horn on 

 orbit. No tubercles on back. Fins dorsal begins close to the end of ven- 

 trals, beyond which it does not extend. Colour a network of black lines on 

 the back and root of the pectoral (in.
