Fishes of the Western North Atlantic 267 



Apparently this fish does not occur off southern Florida, for it was not reported 

 by Longley and Hildebrand from collections made at Tortugas over many years, in- 

 cluding dredgings at various depths down to about 400 fms (<S7). This seems to be 

 another instance of a discontinuous range of the genus such as is reported for Pomolobus, 

 Alosa^ and Brevoortia (p. 343). However, in Etrumeus the inhabitants of the Gulf and 

 the Atlantic appear to be identical, whereas in the other genera named, the inhabitants 

 of the two areas differ sufficiently to be recognized as distinct species.

Characters.'' A very small species. Body slender, compressed; abdomen rounded; 

 chest with suggestion of a keel. Bony scutes absent. Scales deciduous, very thin, 

 with smooth edges, covering abdomen. Snout moderately long, tapering. Mouth 

 terminal. Maxillary narrowly rounded, terminating about under anterior margin of 

 pupil. Teeth in a single series on the margin of maxillary and premaxillary; a short 



6. Because of such inaccurate statements in the original description as "Mouth. . .toothless," "Lower jaw projecting," 

 and "A. 15," it was long questioned whether sadina was available for this species. However, the description con- 

 tains pertinent remarks such as "Form neat, tapering, and slender," and especially "the beUy is not at all serrate, 

 but quite smooth," which can scarcely apply to any other clupeoid. Therefore, sadina certainly seems available. 

 Apparendy Alosa teres DeKay, though much better described and rather well figured, must rest in synonymy, 

 under the rules of zoological nomenclature. 



7. Bertin (jj: 17) has stated that Jenhinsia is not separable from Spratelloides Bleeker. — G. S. Myers.
