small acute teeth on the vomer as VALENCIENNES did, and believe that 

 KBOEIJER had overlooked them. Denmark's Fislce, in. 1846, pp. 276 277. 



The spines have a lively green colour. The ribs are very delicate, and 

 the gill-covers thin, transparent, bony plates. Very young fishes have been 

 met with about i" long, with a short upper snout which has been regarded 

 as a species of Hemiramphus, but are the young of Belone. See such a fish, 

 found by Prof. BEHN in the Baltic in June 1842, and figured and described 

 by him in my Tijdschrift voor natuurlijke Gesch. en Phy&iologie, x. 1843, 

 bl. i 1 i, and HoBNSCHUCH, ibid. bl. 295 300. In the western hemi- 

 sphere also and in the East Indies species of this genus occur, living partly 

 in fresh water, partly in the sea. 



Scomberesox LAC., Sayris RAFIN., BONAP. Teeth very small, 

 in a single row in both jaws ; palatine teeth none. Tongue smooth. 

 Snout acuminate, protracted, lower jaw the longer. Branchial 

 aperture large. Branchiostegous membrane with 12 15 rays. 

 Body elongate, compressed, with small deciduous scales. Several 

 pinnules behind dorsal and anal fins, as far as caudal fin. 



This genus is very similar to the preceding, and is principally distin- 

 guished by the many small dorsal and anal fins. A species has been found 

 in the Mediterranean Sea, Scomberesox Rondeletii VALENC., Saurus RON- 

 DELET, dePiscib. p. 232, BONAP. Faun. Ital. in. Tab. 122, fig. 2, which is 

 distinguished from that of the Atlantic Ocean and the North Sea (Scomber- 

 esox Camperi LACEPEDE, Poiss. v. PI. 6, fig. 3, YARRELL British Fishes, 

 I. p. 394), according to VALENCIENNES, by the absence of a swimming- 

 bladder.

HemirampJius Cuv. Teeth small, crowded into a narrow belt 

 around the margin of each jaw ; palatine teeth none. Symphysis 

 of lower jaw produced into a narrow process beyond the row of 

 teeth ; upper jaw short, triangular. Branchiostegous membrane 

 with 10 14 rays. Scales large. Body elongate, with back 

 rotundate or flat.

 Jamaica, Tab. 45, fig. 2. Encycl. mtth., Poiss. PL 72, fig. 298 ; West Indies 

 and Atlantic Ocean. There are also species in the East Indies, amongst 

 which Hemiramphus longirostris VALENC., Cuv. R. Ani., ed. ill., Poiss., 

 PI. 98, fig. 2, is distinguished by very large pectoral fins. 



Exocoetm L. Teeth very small in the anterior part of both 

 jaws. Palate edentulous. Gape of mouth small. Branchiostegous
