Dr. Bleeker makes this species to be identical ^^ithhis Upinephelus 

 fasciatus. If so, the fresh specimens are distinctly marked with 

 six or seven short brown fasciae on the back. It is also identical 

 with S. oceanicm of Cuv. and Val. It is widely distributed 

 throughout the Indian and Chinese Seas.
