The inner borders of the breast-fins approach one another before 

 the head, diminishing obliquely inwards, and from the fore point of 

 the disk, as in Trygon. The hinder edge of the belly-fins is only 

 very slightly undulated, hence the belly-tin is not divided into two 

 lobes. Tail-fin as in Raja.
