width. In the smallest example space between front tip of lower 

 jaw and snout tip slightly less than snout measured from its tip to 

 eye. All have a distinct projecting point to the nasal valve. Very 

 slight outer fold at mouth corner. 



Ranzani's lateral figure- shows the nostril near the last fourth of 

 the snout as seen in profile. His lower view of the head shows it 

 slightly behind middle in snout length, as measured from snout tip 

 to eye. Also the mouth length is shown greater than its width 

 and without any trace of a short groove at the outer corners. His 

 specimen was about 1,171 mm. long. 



Scoliodon lalandi (Mailer and Henle). 



One example, 425 mm. long. Width of snout at outer nostril edges 

 shorter than space between snout tip and front tip of lower jaw by 

 nearly length of nasal aperture. Nostrils about last y in snout lengths 



Compared with Scoliodon terrce-novce from Holly Beach, New 

 Jersey, the width of snout, as measured above, of nearly equal 

 length with space between snout tip and front tip of lower jaw. 

 This species also shows the nostril about last | in snout. 

 Albula vulpes (Urm6). 



Eight examples, largest 324 mm. long. 



Sardinella humeralis (Valenciennes). 



Nine, largest 152 mm. 



Opisthonema oglinum (Le Sueur). 



Three, 105 to 162 mm.

 scales about 34? (according to pockets) in lateral series to caudal 

 base; about 14? scales (squamation injured) between dorsal and anal 

 origins; head width 2| its length; head depth ly; dorsal base 2j; 

 mandible 2; lea.st depth of caudal peduncle 3|; lower caudal lobe 1^; 

 pectoral If; first branched anal ray 2f ; snout 4 in head measured 

 from upper jaw tip; eye 2|; maxillary 1|; interorbital 5|. 



Body strongly compressed, thin, deepest at ventral origin, edges 

 slightly trenchant, abdominal edge with 20+6 serrae forming 

 trenchant keel, profiles similarly convex. Caudal peduncle com- 

 pressed, length about equals its least depth. 



Head compressed, sides moderately flattened, strongly convergent 

 below, upper profile moderately inclined and lower more so. Snout
