Greatest height of the body is contained 4^ times in the total length, 

 and the length of the head 4f in the same. The diameter of the eye is 

 one-fifth of the length of the head, and the length of the snout one-third. 

 The dorsal tin commences above the root of the pectoral, and extends 

 to within a short distance of the caudal fin ; its length is slightly more 

 than one-half the total length ; first dorsal spine the shortest — one-nine- 

 teenth of the total length of the fin ; the longest spine between one- 

 seventh and one-eighth 5 the longest soft ray between one-fifth and one- 

 sixth ; and the last ray about one-fifteenth of the length of the fin. The 

 anal fin commences under the fourth soft dorsal ray, and terminates oppo- 

 site the end of the dorsal ; its length three-fifths of the length of the dorsal ; 

 its height one-fourth of its length. Pectoral long and pointed, some- 

 what shorter than the head ; the middle ray the longest. Ventrals com- 

 mence under the hinder margin of the base of the pectoral, and are con- 

 tained If times in the length of the latter. Caudal peduncle is 12^ 

 times in the total length ; its height about one-fourth of the greatest 

 height of the body. Caudal fin about 6^ times in the total length. 

 Total length 18.50 inches.

Our specimens agree with Giinther's description in every particular, 

 except in the number of soft rays in the dorsal fin. The measurements 

 are identical, as are also the arrangement of the scales and color. 

 What is very characteristic of this fish is the condition of the dorsal 

 and anal fins. It is the only species of this genus in which these fins
