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.

 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,
