DIAGKAMMA. 27 



The upper profile, between the end of snout and commencement of dorsal, forms 

 nearly a quadrant, the centre of which lies between the roots of the pectorals and ventrals ; 

 the lower profile is nearly straight between the snout and anal. The diameter of the eye 

 is contained three times and a half in the length of the head. The height of the body is 

 contained three times and a half in the total length ; the length of the head is one-fourth 

 of the same. The distance of end of dorsal from caudal is greater than the height of 

 the tail below the former. Dorsal not notched, with moderately strong spines, of 

 which the third is longest ; it is contained twice and a half in the length of the head ; 

 the scaly sheath covers the basal third of the soft dorsal. The second anal spine is 

 shorter but stronger than the third, which is contained twice and two-thirds in the 

 length of the head. Caudal scarcely emarginate.
