 f of distance to origin of soft dorsal. Soft dorsal inserted posterior 

 to origin of anal, much nearer origin of spinous dorsal than base of 

 caudal, and anterior rays much higher than others. Anal with ante- 

 rior rays longest. Caudal emarginate. Pectoral rather broad, high, 

 and reaching about opposite root of ventral, ^^entral small, inserted 

 much nearer origin of anal than posterior rim of orbit. Anus placed 

 about first third of space between tip of ventral and origin of anal.

 below. Side of body with a narrow silvery longitudinal band, nearly as 

 wide as pupil of eye, extending to base of caudal. Fins pale brown,

Type No. 15,397, A. N. S. P. Italy. Bonaparte Coll. Dr. T. B. 

 Wilson. 



Twenty-nine co-types with same data. 



Ten examples. Same data. (No. 345.) Identified as " Atherina 

 sarda." 



This species may be found identical with Atherina sarda Valenciennes, 

 but the latter is said to have D. VI-9, A. 10. The description, like 

 that of Atherina coryieda Rafinesque, is too imperfect to permit of 

 identification. 



{Sarclinella, diminutive of Sarelinei, a sardine.)

Type Atherina laticeps Pocy. 

 Rami of mandible not elevated inside of mouth. Anus well anterior
