Scales very small, ciliated ; a series of minute spines along the 

 base of the dorsal and anal fins. The height of the body is contained 

 once and four-fifths in the total length (without caudal) ; the length 

 of the maxillary is nearly one-fourth of that of the head. The width 

 of the inte^orbital space equals the diameter of the eye f. The lower 

 eye is much in advance of the upper. The length of the caudal fin 

 is one-sixth of the total. Brownish, with numerous rounded bluish 

 spots ; a black spot on the lateral line.

D. 85-91. A. 70. 

 Scales very small, ciliated ; those along the base of the front part 

 of the anal with a minute spine each. The height of the body is 

 contained once and three-fourths in the total length (without cau- 

 dal) ; the length of the maxUlary is nearly one-fourth of that of the 

 head. The width of the interorbital space is much more than that 

 of the orbit, varying according to age, but always more than one- 

 third of the length of the head J. The lower eye is much in advance 



* Exactly the same numbers are stated by Bonaparte. 



t Total length of the specimen 41 lines, of the head 9 J lines ; width of the 

 interorbital space 2 lines. Width of inter- 



J Total length. Length of head, orbital space.
