The last dorsal spines are rather longer than the first rays. The

 Preeorbital and praeoperculum not serrated. The spines are mode- 

 rately strong ; the length of the second of the dorsal being four- 

 sevenths of that of the head and two-fifths of the depth of the bo^'' , . 

 The second and third anal spines are considerably shorter than tluse

The height of the body is contained twice and four-fifths in the 

 total length, the length of the head four times ; the diameter oi the 

 eye is contained thrice and two-thirds in the latter. Praeorbital and 

 praeoperculum finely serrated. The second dorsal spine is strong, 

 one-third of the height of the bofly, equal in length to the second 

 and third anal spines, the former being stronger than the latter and
