ray of fin; origin of adipose dorsal about half way* between tip of 

 last dorsal mj and base of caudal; anal small, its origin before adi- 

 pose fin; caudal deeply emarginate with pointed lobes; pectoral 

 small, not reaching to dorsal; ventrals large, reaching about to end of 

 base of dorsal. 



Color in alcohol, dusky above, sides and belly yellowish, sides of 

 back with about eight or nine dusky cross bars or pairs of bars, these 

 often taking the form of quadrate spots with paler center; an oblique 

 black spot on upper part of opercle; jaws barred ; fins, except the pec- 

 toral, faintly barred. In life, in Japan as in Honolulu, some speci- 

 mens have l)rick-red markings while others from shallower water are 

 olive green. The first are called Akaeso (aka meaning red), the others 

 Ise eso, from the province of Ise. This fish is common throughout 

 the western Pacific from Hawaii to the coasts of Japan. We have 6 

 specimens from Wakanoura and 3 from Nagasaki. This species is 

 closely allied to the rare Atlantic species, Synodus synodus (Linnaeus), 

 with which Doctor Bleeker unites it. Specimens of the Atlantic spe- 

 cies examined from Bahia have, however, larger scales (58 instead 

 of 65.) If the Pacific Coast species is really distinct, it must appar- 

 ently stand as Synodus japonicus.
