expanded and fan-like ; preopercular border with two 

 series of blunt spines, the inner 3 the outer 5 in number ; 

 a similar spine behind the angle of the mouth ; opercle 

 with 2 high smooth edges, which do not terriiinate in spines ; 

 frontal and occipital pits, cheeks, a small temporal patch, 

 and the upper angle of the opercle covered with smootli 

 naked skin. Upper part of body with a few small papillae. 

 Length of soft portion of dorsal fin 2*25 in that of the 

 spinous ; 1 st dorsal spine lower than the 4 succeeding and equal 

 to the middle spines, beyond which they again increase 

 gradually in height to the last spine, which is the longest 

 and 1-2 in the 5th ray, which extends when depressed 

 well beyond the base of the caudal. Third anal spine 

 longest, 1.5 in the middle rays, which just reach the caudal ; 

 the membrane of the last dorsal ray extends to the caudal, 

 that of the anal not so far. Caudal small and rounded ; 

 depth of caudal peduncle equal to the eye-diameter. Pec- 

 toral fin wide, its basal width r4 in its length ; 5th ray 

 longest, reaching to the vertical from the vent, the lower 

 rays unbranched. Middle ventral rays equal and longest, 

 extending rather more than midway to the anal. 



Uniform dark brown above, pale brown below. Upper 

 surface and sides of head with some scattered pearly spots. 

 Spinous dorsal pale brown with one or two lighter blotches ; 

 soft dorsal dark brown with an oblique lighter band directed 

 downwards on its anterior half ; anal and caudal yellowish 

 brown with black cross-bars, which frequently branch and 

 cross one another so as to form a lattice- work pattern, the 

 latter also with a dusky base ; pectoral with the basal 

 half pale lavender, beyond which superiorly is a blackish 

 blotch, its distal half golden crossed by three narrow blac^k 

 bars, the last of which is marginal ; inferiorly the two 

 inner bars anastomose like those of the caudal.* (Named 

 for the Brothers Crouch, to whom I am indebted for this 

 unique specimen.)
