 to 37-9. Body rather short and deep, somewhat compressed, the back

14»S. MICROPERCA FONTICOIiA (Jordan & Gilbert). 



Head 3h to 1 ; depth H to 5. D. VI or VII-8 to 10 ; A. I, 7 ; scales 34. 

 This species or variety is very close to the northern Microperca punctulata. 

 The only tangible differences seem to lie in the coloration and in the con- 

 stant presence in Microperca fonlicola of but one anal spine. The head 

 in Microperca fonticola is nearly or quite devoid of scales. In life, light oliva- 

 ceous, the scales broadly margined behind with dusky ; about 8 indistinct 

 dusky cross blotches on back, the dorsal region dusted with fine dusky 

 specks ; a series of dark, stitch-like, short horizontal lines along the
