nearly 1^ times in interorbital width and 6 times in length of head. 

 Maxillary reaches to vertical of about the distance between point 

 of snout and anterior margin of eye. Profile from origin of dorsal 

 to point of snout convex. 



Dorsal 17, commences a little nearer to base of caudal than to 

 point of snout, and f of its base is situated in advance of the 

 ventrals ; anterior rays nearly f length of head, posterior margin 

 of fin slightly concave. Pectorals f length of head. Ventrals over 

 -^ length of head, inserted below last 4th of dorsal. Anal 8 ; about 

 ^ length of dorsal and -| height. Caudal forked, upper lobe longest 

 and about -^ length of head. Lat. 1. 70, nearly straight ; lat. tr. ^-. 



Colour (of preserved specimen), silvery, darker above. 



One specimen, 350 mm. in length, from Mr. Eomer Eobinson, 

 Natal. 



EfcOPS SAUEUS, L. 



(Springer of Durban, Cape Salmon of Port Elizabeth.) 



Depth of body 5f times in total length excluding caudal, length of 

 head 3f times. Snout equals diameter of eye, which is 4^ times in 

 length of head ; interorbital space diameter of eye, slightly concave 

 and grooved ; lower jaw slightly longer than upper and rather 

 thickened at extremity, maxillary extends about % diameter of eye 

 behind orbits. 



Dorsal 23, commences nearer to base of caudal than to point of 

 snout, highest in front with a concave upper edge ; 5th ray longest 

 and f length of head. Pectorals and ventrals about same length, 

 J length of head. Anal 15 ; similar to dorsal but rather more con- 

 cave and slightly more than f the height. Caudal rather longer 

 than head, deeply lobed. Scales, 11 rows between lateral line and 

 base of ventrals, a few rows form a sort of sheath to dorsal and anal 

 fins. Lat. 1. 100, lat. tr. if. 



Colour (of preserved specimen), silvery. 



One specimen, 196 mm. in length, from Natal. 



MEGALOPS CYPKIXOIDES, Brouss. 



Depth of body 3^ to 3| times in total length excluding caudal, 

 length of head 3f to 4 times. Snout equals interorbital width and is 

 f to f diameter of eye, which is 3-f to 3|- times in length of head. 

 Eye with anterior and posterior adipose lids, each about J diameter 

 of orbit; lower jaw projects beyond upper, chin prominent, cleft of 

 mouth oblique, maxillary reaches to vertical of posterior margin 

 of orbits or slightly beyond it.
