- Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 26 , Xenobalistes punctatus, the second species of the peculiar balistid genus Xenobalistes, is described from one specimen found on the beach at the mouth of the Van Stadens River, eastern Cape Province, South Africa. X. punctatus differs significantly from X. tumidipectoris Matsuura, 1981 in the number of body scale rows and spination of the anterolateral surface of the first dorsal-fin spine. The head and body of X. punctatus are dark brown, covered with numerous, small, evenly-spaced, silvery/white spots.

- Description: A new species of stingray, Hexatrygon bickelli Heemstra and Smith, is described from a specimen washed up on a beach at Port Elizabeth on the south coast of South Africa. This new species differs from all other batoid fishes in having six gill arches and a peculiar hypertrophied snout that appears to be a well-developed electroreceptive organ, and in the configuration of its spiracles. Other characters that separate H. bickelli from previously known rays (myliobatiforms) are its small simple brain (other rays have a very large complex brain) and the absence of supraorbital crests on the cranium. In addition, all myliobatiforms are neritic (with none having been recorded below 200 m), and H. bickelli is.presumed to live in moderately deep water (400 to 1000 m). The classification of batoid fishes is reviewed, and Hexatrygon is placed in a new family and suborder of the Myliobatiformes. , Rhodes University Libraries (Digitisation)
