Above greenish olive or greenish grey ; a little behind the occiput

Greatest Breadth : 3 feet. 



The snout is conical and about £ broader than long, and not quite 

 double the length of the nasal valve. The nasal lobule is broad conical. 

 The shape of the disk resembles that of Myliobatis milvus. The 

 dorsal fin commences near the termination of the base of the ventrals, 

 but terminates at some distance in front of the apex of the ventrals. 

 The latter are elongated, about thrice as long as broad. The male ap- 

 pendages do not extend beyond the corresponding margin of the fin, and 

 are shorter in the young. The tail is trigonal as far as the spine, the rest 

 is compressed and flagelliform. Its length is thrice or four times that 

 of the body. The spine is situated immediately behind the termination 

 of the dorsal ; its length equals its distance from the anus. Some in- 

 dividuals are armed with a second somewhat longer spine, a little behind 

 the root of the former. The dental laminae of the upper jaw are very 

 slightly arched ; the anterior margin of the external laminae exhibits 

 numerous vertical denticulations. The laminae of the lower jaw are 

 but § of the breadth of those of the upper, but they are more convex, 

 forming in the centre an obtuse angle. Single young individuals occur 

 at all seasons in the Straits of Malacca. The following dimensions 

 were taken from a young male, armed with two spines :
