RHINOBATUS (SYRRHINA) ANNULATUS. 
oval form. Dorsal fins rather small, placed far back on the body, and each 
truncated behind. Ventral fins small, the hinder and outer edge prolonged. 
Caudal fin somewhat oval, or imperfectly diamond-shaped, the upper part 
posteriorly most prolonged. The spines in the course of the dorsal line are 
very short, slender, obtuse, and scarcely visible in the fresh fish ; and the 
skin, if stroked from the head, is smooth ; if towards the head, rough. The 
eye-like variegations are alike, as regards number and position, on both 
sides.

The first specimen of this fish which I procured, was taken in a seine near the mouth of the 
Cowie River, and I have seen others of the same species caught in Algoa Bay. It has not yet 
been found to the westward of Cape Point, nor is it known to the fishermen of Simon’s Town. 
It is always found in situations where the bottom of the sea is level and sandy.
