the longest ray is three eighths as long as the head; the last ray 

 two thirds as long as the eye; the fin is followed by two finlets, 

 the longer as long as the eye. The ventral reaches a little be- 

 yond the origin of the soft dorsal; the length of the fin is equal 

 to snout and eye combined. The pectoral is as long as the ven- 

 tral; it reaches to below the last spine of the dorsal; the fin 

 originates slightly in advance of the ventral insertion. Body 

 covered with small, cycloid scales; head naked except on sub- 

 orbital and postorbital regions; scales extending somewhat on 

 bases of soft dorsal and anal fins. D. VI-I, 26 to 27, 2; A. II, I, 

 16 to 17, 2; V. I, 5; P. I, 20. Scales 16-110-20. 



Color of upper parts bluish; lower parts pale yellowish; 

 caudal fin yellowish, the margin dusky; ventrala and pectorals 

 yellowish tinged with blue; a blue band as wide as the eye from 

 orbit to upper margin of caudal peduncle; another from snout 

 along lower margin of orbit and continuing to the caudal, pass- 

 ing above the pectoral. 



The runner is recorded from the East Indian archipelago, 

 Polynesia, and tropical parts of the Atlantic, straying north- 

 ward in summer, rarely to Long Island, where specimens have 

 been taken by Dr Seth E. Meek and John B. De Nyse. The fish 

 attains to the length of 30 inches. The example captured by 

 Mr De Nyse was taken in his pound at Gravesend bay Aug. 2, 

 1895; it is now preserved in the IT. S, National Museum. The 

 length of the specimen is about 15 inches. Young fish, about 

 4 to 6 inches long, are before me from Florida and Cuba.
