 Paracentropotjon ]'>leekkh, Act. Sci. Roy. Ainst., 1876, p. (56, {longispini<s) . 



Body oblong, compressed, rovered with minute scales or almost 

 naked. Head obtuse, without spinous crests. Preor])ital with two 

 spines, pi-eopercle with 4 or 5; opercle with 2; mouth moderate, 

 ol)li<iu(>, the jaws subequal; teeth on vomei- and palatines; no barbels 

 at tile ciiiii; "ills ;>j, no slit behind the last; pectorals moderate, with- 

 out free rays; dorsal continuous, not joined to the caudal, the spines 

 12 ro 14, the tirst inserted over the eye, the anterior spines strong and 

 divcroent; soft rays 8 or 9; ventral l•a^^s I, 4; anal rays 111. 4 to 0; 

 caudal rounded. Small brightly colored tishes, with stinging spines. 

 They are distinguished from the genus Tetraroge chiefly b}'^ the absence 

 of barl)els. From (ryjiinapistus {Pentraroi/t^) the absence of a slit 

 behind the last gill is the chief distinction. Both Tetraroge and Gyin- 

 ixijttstiix are said to have the ventral rays I, T), but V^alenciennes incor- 

 rectly assigns the same number to Parncentnypogon loiujUplnlx.
