WKASSES. 529 



This fish {E. insidiator) is said to seize marine animals 

 by suddenly thrusting out its mouth and engulphing those 

 that come within the reach of the elongated tube. It attaias 

 a length of twelve inches, is common in the tropical Indo- 

 Pacific, and varies much in coloration. 



Anampses. — Distinguished by its singular dentition, the two 

 front teeth of each jaw being prominent, directed forwards, com- 

 pressed, with cutting edge. D. ^, A. ^. 



Beautifully coloured fishes from the tropical Indo-Pacific. 

 Ten species. 



Platyglossxjs. — Scales in thirty or less transverse series; 

 lateral line not interrupted. A posterior canine tooth. Dorsal 

 spines nine. 



Small beautifully coloured Coral-fishes, abundant in the 

 equatorial zone and the coasts adjoining it. Some eighty 

 species are known (inclusive of the allied genera Stethojulis, 

 Zeptojulis, and Psevdqjulis). 



NOVACULA. — Body strongly compressed, oblong, covered 

 with scales of moderate size ; head compressed, elevated, obtuse, 

 with the supero-anterior profile more or less parabolic ; head 

 nearly entirely naked. Lateral line interrupted. No posterior 

 canine tooth. D. ^\, A. ^ ; the two anterior dorsal spines 

 sometimes remote or separate from the others. 



Twenty-six species are known from the tropical zone, and 

 the warmer parts of the temperate zones. They are readily 

 recognised by their compressed, knife-shaped body, and 

 peculiar physiognomy ; they scarcely exceed a length of 

 twelve inches. 



JuLlS. — Scales of moderate size ; lateral line not interrupted. 

 Head entirely naked. Snout of moderate extent, not produced ; 

 no posterior canine tooth. Dorsal spines ten. 



Co-extensive with Platyglossus in their geographical dis- 

 tribution, and of like beautiful coloration and similar habits. 

 Some of the most common fishes of the Indo-Pacific, as J. 

 lunaris, trilohata, and dorsalis, belong to this genus.
