SCYLLIUM PANTHERINUM. 
the fourth branchial opening ; the external and posterior sides of ventral 
fins nearly of equal length, the edge of the latter slightly oblique, the outer 
angle much rounded, the inner subacute ; anterior edge of dorsal fin slightly 
arched ; the base of anal in length equal to twice its depth. Skin covered 
with scales like those of Scyllium Africanum.

Specimens of this species are occasionally procured from the sea which washes the eastern 
coast of South Africa, and the few individuals I have seen were all taken in the neighbourhood 
of Algoa Bay. The peculiar and beautiful markings of this species furnish characters by 
which it is to be readily distinguished from S. Africanum. In addition to colour, however, 
there are other discrepancies ; the greater proportional depth of the anal fin as compared 
with the length of its base ; the difference in the shape of the anterior edge of the first dorsal fin, 
the greater length of the cirri, and each crossing the inner extremity of the nostril, instead 
of nearly midway between its extremities, as happens in Scyllium Africanum.
