EDIBLE EISHES OP NEW SOrTH WALES. 143 



are broadest below : dorsal with four narrow longitudinal violet bands and 

 small spots ot" the same color between them ; an olive green blotch between 

 the second and third spines ; anal with irregular rows of violet spots separated 

 by golden bands ; caudal with violet bars between the rays ; pectorals and 

 veutrals immaculate : irides crimson. 



How or why this fish obtained its vernacular name it would be difficult 

 to say, since it is not a native of New Zealand, nor indeed is the genus 

 tepresented there, so far as our present knowledge goes. 



Though obtainable in the market in considerable quantities and at all 

 seasons of the year, nothing appears to be known definitely as to time or 

 place of its spawning. They frequent rocky shores, and are partial to 

 sheltered spots where patches of sand are interspersed among the weed- 

 covered rocks ; in such places on a calm day they may be observed swimming 

 slowly to and fro, and may be caught with the greatest ease by dropping a 

 hook baited with crab or yellowtail in front of them. 



Their food consists of small crustaceans, molluscs, and such other organisms 

 as they can pick up among the rocks which they frequent. As food it is 

 superior to the Parrotfishes. 



As is the case with so many of our Labrid Tishes, the Maori, which is 

 abundant on the coast of New South Wales — where, however, its range 

 northwards is as yet undetermined — has not so far been included in the 

 later lists of Victorian or Tasmanian Fishes, but reappears at Adelaide 

 according to Castelnau {Julis adehtidensis), aw^L at King George's Sound, 

 whence it was received by Eichardson and Klunzinger, while the British 

 Museum contains examples from Swan Eiver, West Australia ; the type 

 specimens are, however, said to have been obtained by Quoy and Graimard 

 at Western Port, Victoria. 



The Maori grows to a length of sixteen inches.
