longest ; ventral slender, somewhat shorter than the pectoral, with 

 the outer ray longest. The first dorsal fin commences in the ver- 

 tical from the prseopercular margin ; the two anterior spines are a 

 little higher than the second dorsal, and flexible ; the membrane 

 behind the third spine extends backwards to the base of the second fin. 

 All the spines of the second fin are stift' and pungent, of nearly equal 

 length, the anterior ones being a little the shorter ; the membrane 

 of the last spine terminates immediately before the base of the caudal, 

 leaving that fin quite free. Caudal rounded, one-seventh of the total 

 length. The anal commences below the seventh spine of the pos- 

 terior dorsal, and terminates before the caudal ; it has two spines 

 anteriorly. The scales are of moderate size ; the lateral line runs 

 closely along the dorsal profile, is bent downwards behind the pec- 

 toral, and proceeds along the middle of the tail to the caudal. 



Brownish, irregularly marbled ^^'ith darker ; anterior dorsal black- 

 ish ; a black ocellus, edged vnth white, on the nineteenth and 

 twentieth spines of the posterior dorsal.
