VARIETIES OF GURNARDS. 105 



The Streaked Gurnard, or the Unbearded Mullet 

 {Micllus imhehris, Trigla lineata). It is a rare fish, and 

 has its pectoral fins coloured like the end of the tail of 

 a peacock. 



The Grey Gurnard, Gowdie, Hardhead (CztcitZHS grisens, 

 Trigla gurnardus), Crooner, Croonack. To "croon" mean-

 common fish in the British markets, and is caught on 

 the northern coasts of Scotland and Ireland, as well as 

 in the south and west of England. It generally lives 

 at the bottom of the sea, but often ascends to the 

 surface in fine weather in large numbers.

 reaches a foot in length. 



The Little Gurnard (Trigla p(Xciloptera). I have 

 never seen a specimen ; it is said to be taken at Wey- 

 mouth. 



The head of the gurnard is so armed with bones as 

 to remind one of the appearance of knights in armour. 

 They are also furnished with three rays at the base of 

 each pectoral fin, which help the fish, as organs of touch, 

 to find its food at the bottom. 



These three rays are used in a very peculiar manner. 

 In June, 1843, my father, the late Dean of Westminster, 

 read a paper on this subject before the Ashmolean 

 Society at Oxford, which I now quote, as it has never
