the name is a corruption of the Italian word gianitore 

 (gatekeeper). Cunningham l gives an interesting picture 

 of how the Dory, which is so depressed laterally as to 

 foreshorten to the merest line, stalks small fishes ; and I 

 have repeatedly had the opportunity of observing this in 

 the clear water beneath Bournemouth pier, where several 

 dories take up their quarters each summer. The tragedy 

 was continuous. First, the sand-eels harassed the " mack- 



erel-midge " ; then a pollack would dash out from the 

 piles, miss the agile launce, and have to content itself 

 with a small sand - smelt ; lastly, a more leisurely dory 

 would rise slowly from the depths, and, approaching end

 mobile mouth. The dory is to some extent, and within 

 limits not satisfactorily fixed, a migratory fish. It appears 

 to spawn at the end of summer, and occurs as far north
