 tures are (1) the bright reddish-orange tips and margins of the 

 caudal, anal, ventral, and pectoral fins; (2) about four somewhat 

 irregular white bars, one across caudal peduncle, one extending 

 somewhat obliquely from under anterior end of soft dorsal to ante- 

 rior end of anal; belly and throat white or nearly so, showing a 

 slight greenish tint in some specimens; the general ground color of 

 sides and back a very dark brown, but on close examination 

 each scale is seen to be broadly margined with dark brown, while 

 centrally they show more or less of a light greenish or brownish 

 gray with decided metallic luster; under surface of opercle very 

 dark except for a broad marginal zone of dusky white; soft dorsal 

 faintly tipped with reddish-orange.
