EDIBLE FISHES OF QUEEN SLAM)— OGILBy. 03 



purposes. These fishes are of consideriible value for the table, and the isinglass 

 obtained from their air-bladders or "soiinds" is of good quality. I recognize 

 only the following species as belonging to the restricted genus Otolithus.

Note: — Otolithus leiiciscus Gunther,-" from Manila, is I'eferred to this 

 genus by Jordan and Richardson,-' but since its describer expressly writes "the 

 lower jaw without canines in front" 1 can not admit the correctness of their 

 identification. Also Scale describes two Bornean species as 0. dolorosus'- and 

 0. uric/ifalis--; unfortunately the paper in which they are described is mis.sing 

 both from our library and that of the Australian Museum, Sydney, and I am, 

 therefore, perforce, obliged to omit them, owing to the loose wa.y iri which the 

 generic name has been applied in the past.

SILVER TERAGLIN. 

 Type locality : — Java. 



Body slenderly elliptical and compressed, the dorsal contour considerably 

 more arched than the ventral, which is gently rounded between the isthmus and 

 the anal fin, its width 1-75 in its depth, which is 3-8 in its length and 1-16 in the 

 length of the head. Abdomen long, its length from ventral-base to vent 2-75 in 

 that of the body and as long as the space between the vent and the root of the 

 caudal. Caudal peduncle one third longer than deep, its least depth 3-38 in the 

 length of the head. Head about one fourth deeper than wide, the fronto-occipital 

 profile linear and but little acclivous, passing imperceptibly into the gentle 

 oecipito-nuchal convexity, its width one half of its length, which is 3-33 in that 

 of the body. Snout pointed, with convex profile, its length one fourth of
