THE ANGLER-NATURALIST. 



fishes is that of a slender elongated cone, slightly curved 

 inwards to assist in holding a struggling prey * ; in herbi- 

 vorous fish the form is commonly that of a short rounded 

 tubercle with a flat crown, adapted for crushing. Some- 

 times the teeth are so small and numerous, more especially 

 in insect-eaters, as to have the appearance of the hairs of 

 a brush ; and occasionally they are thin and flat, with a 

 cutting edge. By these characteristics the habits and food 

 of fishes may usually be as readily discovered as those of 

 graminivorous and carnivorous animals by the same means.

The woodcut represents one-half of the " throat-teeth," 

 looking from behind, in the Carp, Tench, Roach, and 



* Teeth of this shape are termed aticular ; if stouter, subulate ; if 

 teeth are hair-like, and short and densely crowded, they are said to be 

 villiform', if longer and equally slender, cUuform; if stronger and 

 stiffer, setiform, or brush-like ; if still coarser and curved, card-like ; 

 when much shorter than the latter they become raduliform, or rasp- 

 like. Conical teeth longer and stronger than the others on the jaw 

 are named canines; and those with broad flat crowns, molars, which 

 is the name given to the large flat teeth of the Carp, shown in the 

 engraving. These names take their origin from the Latin words 

 acicula, a small needle ; subula, an awl ; villus, a fleece ; cilium, an 

 eyelash ; seta } a bristle or brush j radula, a scraper j cams, a dog j mola, 

 a mill.
