D. X, 9, I, spines uniformly high or last but very slightly longer 

 than first, 2}^ in head, first ray 1%, eighth ray 1^^; A. Ill, 8, i, third 

 spine 2%, seventh ray 1%; caudal 1, deeply emarginate ; least depth of 

 caudal peduncle 2}^; ventral 1; pectoral 3K in combined head and 

 body to caudal base. 



Uniform. Bases of membranes of dorsals and anals each with 

 small dark spot, also each fin with dark submarginal line. Dark 

 area on second ventral ray medially. Length, 270 mm, (Jordan 

 and Evermann.) 



Formosa. Apparently known only from the type. Jordan and 

 Evermann have, however, confused another fish at the end of their 

 description, evidently a Serranus. Possibly, to judge from the last 

 paragraph, it may even refer to a third fish. Nemipterus matsubarae 

 certainly differs from any species of Dentex known to me in the 

 diminished rows of scales on the cheeks.
