This species has hitherto been known from the warm 

 parts of the Atlantic Ocean, the Indian Ocean and Japan. 



A single specimen, .47 m., was brought into the San 

 Diego market Oct. 31, 1889, another Dec. 15, 1889, by 

 the Portuguese fishermen. It was pointed out as some- 

 thing rare, and with the statement that it was common in 

 Portugal. It was provisionally identified with E. pelamys 

 (L.), though it differs from the description of that species 

 in having no teeth on the palate, and but seven dorsal 

 finlets, and from the figure in Goode, History of Aquatic 

 Animals, pi. 95 b., in having the lateral streaks of the side 

 continued forward to the shoulder. 



Head, 3I to end of middle caudal rays; depth, 3^; D. 

 XV— I, 14+VII; A. II, 124-VII.

 extending from the shoulder-girdle backward, the lower

 middle of the eye ; no teeth on vomer or palate ; jaws 

 each with a series of fine, sharp, recurved teeth. Eye 

 large, with anterior and posterior adipose hd, i| in snout, 

 6 in head, about 2 in interocular. Dorsals and anal fal- 

 cate. Pectorals reaching vertical from loth dorsal spine.
