Snout short, sharp point on front disk edge; eye somewhat promi- 

 nent, nearly large as spiracle; mouth feebly incurved, upper jaw with 

 3 undulations; lower less so; teeth small, white, in oblique rows, 

 with transverse keel faced behind well-marked concavity ; 2 series of 

 oral papillae, 4 in front equidistant and 3 behind ; interocular width 

 2% in snout from eye. 



Skin with small polygonal scutes or more or less rounded, sparse 

 upon snout and disk above, more numerous upon head and median 

 region; somewhat beliind center of back large rounded pearl-like 

 scute, followed by smaller ; more posteriorly series of spinif orm scutes, 

 prolonged upon tail nearly % its length, which considerably more 

 remote than insertion of caudal spines. 



Tail 2l^ to 3 times longer than disk, armed with 2 short spines 

 marked each side with 2 feeble grooves, below 2 other grooves deeper 

 and approaching each other so convex space separated resembles 

 an elevated keel ; these 4 indistinct grooves at tail base well marked 

 medianly in their length and nearly to their extremity, appearing to 

 form above and below rudimentary cutaneous fold; pectorals form 

 subcircular disk, somewhat longer than broad, front edges partly 

 linear, outer angles rounded and hind angles narrowly rounded; 

 ventrals subtriangular, outer angle moderately prolonged. 



Above very pale, with reddish-brown spots, irregularly rounded, 

 often confluent, paler in centers, compact so pale coloration gives 

 aspect of network. Rest of tail and all body below white. Length, 

 655 mm. (Chabanaud.) 



Indochina. Said to be near Dasyatis inibricatus though its colo- 

 ration suggesting Dasyatis favus.
