fourth shortest, thus forming a notch ; dorsal ending with an unbranched soft ray, the joints visil >le under 
a strong lens; membrane of dorsal joined low to caudal; anal origin under eleventh dorsal spine and 
decurved portion of lateral line; pectoral reaching past front of anal; ventral moderate, of 3 rays, 
innermost shorter and slenderer.

gray, like ground-color of dorsal and anal; posterior part of caudal with gray mottlings on rays only, 
this portion separated from the basal part by a space without pigment on rays or membrane, making a
