Males are immature at 176mm TL, adolescent at 235mm TL, and mature at 298mm TL to 326mm TL, which is very similar to that reported by Bass et al. (1975), although they report maximum size as 34cm.

Faint twin V-shaped markings reported on both dorsal fins of fresh specimens, apparently fade with preservation. Ventral colouration is off white to grey-brown or pale mustard, no markings on the underside of fins, although fin webs darker, red-brown, sensory pores on underside of head and trunk black, these faded on some preserved specimens.

At the time, Gilchrist was conducting marine surveys aboard the S.S. Pickle. Upon inspection of the log of the S.S. Pickle during that period, it is apparent that the vessel was travelling continuously between Cape and Natal waters, which may have led to the error. Furthermore, the holotype was described from a preserved specimen (Gilchrist, 1922), which may support the notion that the locality data accompanying the specimen was erroneous.</paragraph>

as described above, the designation of a neotype is warranted in accordance with Articles 75.1 and 75.3 of the International Commission for Zoological Nomenclature (ICZN, 1999). The designation of a neotype from Red Cliffs, Bazaruto Island, Mozambique results in the type locality changing to Red Cliffs, Bazaruto Island, Mozambique in accordance with Article 76.3 (ICZN, 1999). The ambiguity of the original type locality, and the (previous) abundance of this species in the region of the current type locality, will serve to stabilise the taxonomy of this species.

Compagno (1988) gives the locality of RUSI 6128 (neotype designated herein) from off of Kenya in the body of his text, however this is incorrect. Compagno (1988) referred to this specimen in respect to a recently collected “regani-like” shark from east Africa, however the size reported by Compagno (391mm TL) is clearly not this specimen, which is 298mm TL. It may be that the specimen that Compagno is referring to is actually

The conservation status of this species is of concern because Bass et al.

Interestingly, Smith (1949) describes this species as rare, and may be a reference to its occurrence in Cape waters, since it was apparently not uncommon off kwaZulu-Natal at the time, although he lists its distribution as “Cape to Natal”.
