148. Selene oerstedii Luiken. 



Common; brought into the market almost daily with aS'. vomer. It may be at 

 once distinguished from all other members of the genus by the occipital region being 

 scarcely angulated, and by the comparatively large ventral fins. 



The following description is from a specimen 31 cm. in length. 



Head 2| in length; depth if. Eye 4 in head; snout 2; maxillary 3I-. Dorsal VI, I, 18; 

 anal II, I, 15. The profile of snout is less nearly vertical than that of head in front of eye, with 

 which it forms a slight angle just below the level of the eye. In smaller examples the angle is less 

 noticeable. The upper profile forms a broad even curve from just above eye to spinous dorsal. The 

 outline of the body is angulated at front of soft dorsal and anal. 



Teeth small, blunt, and not much crowded, in bands on jaws and palatines, in a quadran- 

 gular patch on vomer. Preorbital space contained 3 times in postorbital space. Gill-rakers contained 

 2\ times in diameter of eye; their number 4-t- 14. 



The pectoral reaches to above eleventh or twelfth anal ray, or to within twice the diameter of 

 the eye of the base of the middle caudal rays. The ventrals reach to the first detached anal spine; in 

 specimens 21 cm. in length, they reach to the first anal ray; in specimens 11 cm. long, they reach 

 to the caudal rays and are about half the length of the entire body. Anterior dorsal and anal rays 

 filamentous. Second dorsal spine as long as the maxillary, reaching when fin is depressed, two-thirds 

 the distance between its base and the front of the soft dorsal. In a specimen 11 cm. in length it is 

 longer than the head by a distance equal to the diameter of the eye. 



Color silvery with bluish reflections above. Spinous dorsal and front of soft dorsal dusky; 

 other fins colorless. In specimens 21 cm. in length or less, the distal half or more than half of the 

 ventrals is black.
