Total length : 6 inch. 



The length of the head is 3| in the total, to the centre of the 

 caudal margin ; but with the muzzle protracted it slightly exceeds 

 I of the total. The diameter of the eye is J of the length of the 

 head. The narrow band of fine flexible teeth in the jaws, is almost 

 hid by the fleshy lips. The lower part of the protracted muzzle is 

 considerably arched downwards. The greatest vertical diameter of the 

 body, in front of the dorsal fin, is \ of the total length. The second 

 dorsal spine is broad, sabre-like, with a sharp edge, and on each side 

 with a narrow longitudinal furrow. The second anal is shorter, 

 but of the same shape. The anterior margin of the third and fourth 

 dorsal, and of the third anal spine is toothed like a saw. Both the 

 dorsal, anal, and ventral spines have the posterior margin transversely 

 striated, a structure also observed in some species of the Genera 

 Apogon, Lacep. and Chanda, Buchan, Ham. The succeeding species 

 of Equula present the same structure of these organs. The length 

 of the second dorsal spine equals that of the head, or | of the greatest 

 vertical diameter of the body ; the third dorsal is J shorter than the 

 second. The second anal spine is even broader than the second dorsal,
