and without spines or cirri. Lateral line incomplete, extending along

Dorsal fins continuous, the spinous dorsal of peculiar structure, the 
five anterior spines forked or Y shaped, the arms of the Y extending 
transversely, the flesh}' fin membrane having a lateral fold on either 
side and a convexity along the dorsal surface, conforming to the 
shape of the spines, the posterior spines shaped as usual; soft rays 
higher than the spines, the longest contained about If times in head. 
Caudal rounded posteriorl3^ Anal inserted below beginning of soft 
dorsal, the rays about equal in length to those of the dorsal; when 
depressed both dorsal and anal reach the base of caudal. Pectorals 
rounded, about If in head. Yentrals pointed, about as long as the 
pectorals. 
Upper sides with a broad, dusky band extending from gill-opening 
to middle of base of caudal where it is darkest; head dark on the 
upper and anterior surface, the opercle with a broad blackish patch 
extending nearly over its surface; a dark longitudinal band covering 
the greater part of spinous dorsal and extending along basal' half of 
soft dorsal, a narrow light band along base of both fins, a second dark 
band on the soft dorsal, separated from the first by a light space of 
about equal width, the fin with a light margin posteriori}'. Caudal with
