1298. DECAPTERUS SCOMBRINUS (Valenciennes). 



Head3i; depth 4f. D. IX-I, 27-1; A. II, 23-1; scales 42, lateral line 

 very slightly bent. Eye large. 3| in head; snout equaling eye; pectoral 

 1 in head. Greenish above; paler below; no distinct opercular spot; 

 no black spots in figure. (Giinther, after Valenciennes.) Galapagos 

 Islands; not seen by us. Close to Decapterus punctatus, the dorsal appar- 

 ently shorter, (scombrinus, mackerel-like.)

1299. DECAPTERUS SANCTJE-HELENJE (Cuvier & Valenciennes). 



Head 4J ; depth 5. D. VIII-I, 32-1 ; A. II-I, 27 or 28-1. Shields 28 

 to 32 (in Japanese examples; 22 to 28 in specimens from St. Helena; 

 Steindachner) ; pectoral 1J in head. Maxillary reaching front of eye; 

 eye moderate, rather shorter than snout. Teeth minute, in single series 

 in jaws ; also on vomer, palatines, and tongue. Bluish, a black opercular 

 spot ; tip of soft dorsal brown. Tropical parts of the Atlantic, on both 

 coasts of South America ; not seen by us. According to Poey this species 

 occurs in Cuba, where it differs from Decapterus punctatus in having its 

 scutes subdenticulate, less narrow, and beginning much behind the 

 origin of the anal. According to Steindachner this species is identical 

 with a common Japanese species, Decapterus muroadsi (Temminck <fc 

 Schlegel).

1300. DECAPTERUS HYPODUS, Gill. 



Head 4 in total ; depth nearly 5. D. VII-I, 21-1 ; A. II-I, 26-1 ; scales 

 70 + 30, lateral line with a very slight sigmoidal flexure, and covered 

 with very conspicuous scales, trifid on each scale. Teeth on lower jaw 

 small and uniserial ; tongue with a longitudinal narrow band. Color 

 above greenish blue, the opercular spot small. Cape San Lucas ; five speci- 

 mens known. It is perhaps a subspecies of Decapterus macarellus, the 

 differences in the size of the teeth being of minor importance and of 

 doubtful permanence, and both forms may be inseparable from Decapterus 

 sanctce-helence. (VTTO, below ; 6r5ot>f, tooth.)
