8. MICROCANTHUS Swainson. 



Microcanilms J^avainson, Class. Anini., II, 1839, p. 21.5 {i^trigatiis). 



This gen us differs from (Jh^iodon chiefl}" in the small scales, there 

 })eing- about 60 in the lateral line. The soft dorsal and anal are shorter 

 than is usual in Chsetodon, the tin formula of the typical species being 

 D. XI, IT; A. Ill, 14. It is in fact doubtful whether the genus con- 

 tains a second species, as the other species with small scales have the 

 soft tins many-rayed and constitute Bleeker's genus llemliaurichtlujs 

 (type, 2)olylepis)^ which is apparently a valid genus. In any case it 

 has no close relation to J/icrocanthu.s strlgatus.

Head 3; depth 2; D. XI, 16; A. HI, 16; P. I, 15; V. I, 5; scales 

 9-6:2-24. Body a little long, deep and compressed; scales more or 

 less uniform on the trunk, small on the head and becoming very small 

 on the soft dorsal, anal, and the base of the caudal. Head moder- 

 atel}^ compressed, the profile steeply convex above the eye; eye 2f in 

 the head and greater than the interorljital space; snout nearh^ straight 

 above, pointed and projecting; mouth moderately large, the maxillary 

 extending to the anterior margin of the eye\ nostrils small, directly in 

 front of, and near the anterior margin of the eye; teeth in a brush- 

 like series in the jaws; interorbital space flatly convex; gill-opening 

 large, the membrane free from the isthmus; gill rakers rather short 

 and in moderate number; dorsal spines strong, longest anteriorly, and 

 graduated to the last, the first and second short; soft dorsal long in 

 front, its niargiii rounded; second anal spine very large and strong; 

 soft anal high in front and then decreasing to the last ray, the margin 

 of the fin nearly straight; pectoral rather short, If in head; ventrals 

 long and pointed, longer than the pectorals and reaching the origin 

 of the anal; caudal with the lobes not produced much, pointed, and 

 the margin concave. Lateral line arched, concurrent with the margin 

 of the seal}' sheath about the base of the spinous dorsal and the mar- 

 gin of the soft dorsal, and then running straight along the caudal 

 peduncle to the base of the caudal. Caudal peduncle compressed and 

 about equal to the ventral spines.
