a black edf^e followed by a lighter inner border, wliicli marking is also 

 present, tliough less distinct, on tlie second doisiil iind upper and lower 

 margins of tlie caudal. 



Described from a well preserved specimen, 48 mm. long, from Murray 

 Island. 



Variation. — Two smaller specimens, 82 mm. long, which were taken 

 with tlie example described, are lighter in colour, the general tint being 

 yellowish, though their markings are sinnlar ; the first dorsal is markedly 

 aiigulai- owing to the greater length of the anterior spines, and the 

 pectorals are longer atid more pointed ; the eye also is proportionately 

 larger. Another specimen 40 mm. long, is intermediate between the two 

 extremes.
