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 interorbital 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 bliiish 

 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 tlii-ee-fouilhs in the total length (without cau- 

 dal) ; the length of the maxillary 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.
