trals inserted only slightly in front of dorsal and much nearer to base of caudal 

 than to branchial opening, the air-bladder divided by many partitions, and the 

 caudal more deeply forked. One Cuban species and the following, which has 

 been described under many names. {Hemirhamphus, half-beak.)

Fig. 64. Half-beak. Hemirhamphus brasiliensis. 



On the coast north of Florida this fish is a straggler and heretofore has 

 been recorded only from Chesapeake Bay and Woods Hole, Mass. A specimen 

 one foot long was taken in Beaufort Harbor in July, 1899, and is included in 

 the laboratory record on the authority of Prof. H. V. Wilson. Another, about 

 10 inches long, was taken in the harbor on June 9, 1904, by Mr. Barton A. Bean, 

 of the U. S. National Museum. This species is abundant from Florida to Brazil, 

 reaches a length of 15 inches, and is said to be a good food fish. 



Family SGOMBRESOCID.^. The Sauries. 



Pelagic fishes of temperate regions, having a strong superficial resemblance 

 to the mackerels (Scombridse) in shape, color, and habits. The elongate body is 

 compressed; one or both jaws are prolonged to form a very weak, slender beak, 

 with feeble teeth; the maxillary and premaxillary are strongly united; the 

 numerous gill-rakers are long and slender; the scales are small, thin, and decid- 

 uous; the fins are small, the dorsal and anal being similar, and posterior to each 

 is a series of finlets as in the mackerels. Several genera, of which only one is 

 found in the Atlantic.
