OCELLATED TRYGON. 



Trygon garra/pa. 



PLATE XXI. 



L. GEBAL, Raya Garrapa. Schorrib. Drawings, No. 69. 



ALL the information that we have regarding this 

 beautiful Trygon is, that it has " a series of rough 

 flat teeth, in each jaw, like a file," and that it was 

 taken in the Rio Branco in April. The general 

 colour of the drawing is a yellow umber- brown, 

 margined round the disk with pale scienna-red, the 

 whole covered with yellowish white spots sur- 

 rounded with a dark margin, large in the centre of 

 the body, and gradually decreasing in size outwards, 

 where they also become more numerous ; a single 

 row of weak spines runs along the upper ridge of 

 the tail, which is also armed about its middle with 

 one large serrated spine. In the drawing the length 

 of the tail about equals that of the body from its 

 insertion to the snout.
