less than that of the body, second dorsal very small, on the 

 tall, opposite the small second anal. In the young, teeth are- 

 present, and the two dorsal fins are connected, the fin being 

 elevated as in the species of Istiophorus. First anal sim- 

 ilar to first dorsal, but smaller, less falcate, and far behind it; 

 pectoral fins moderate, falcate; skin naked, more or less rough, 

 speciall}^ in the young, which have rudimentary scales; sword 

 flattened and trenchant; caudal keel single; intestines long, sinu- 

 ous; air bladder simple; pelvic arch obsolete. Fishes of great 

 size, reaching a weight of 300 to 400 pounds, the flesh red and 

 rich in flavor, highly valued as food. (After Jordan and Ever-

Body fusiform, tapering greatly toward the caudal fin, the 

 head not long, but with a very long upper jaw produced into a 

 beak or " sword," the greatest depth of the body one sixth 

 of total length to base of caudal, file least hight of caudal pedun- 

 cle nearly equal to length of eye. The upper jaw is three times 

 as long as the rest of the head; the ''sword" is broad and 

 rather thin. The' lower jaw extends in front of the eye a space 

 equal to one half of postorbital part of head. The angle of the 

 mouth is well behind the eye. The eye is circular, its diameter 

 one third of postorbital part of head and about tg of total 

 length of head. The dorsal begins over the upper angle of the 

 gill opening; it is ver}^ high, nearly as high as the body, strongly 

 falcate, its upper margin deeply concave, and the posterior rays^ 

 very short. The distance between the dorsals is less than one 

 third of length of head. The second dorsal is very small^ its 

 base only one half as long as the eye, and its hight one and four
