GRAPTOLITHUS, Linnaeus, 1736, Syst. Nat., 1st 

 Ed., but it was not until 1767, in the 

 12th Ed., that any species were defined. 

 [Ety. grapho, I write ; lithos, stone.] Stipes 

 elongated, slender, flattened, or quad- 

 rangular ; they may be simple or bifur- 

 cating; the cells enter the central canal 

 and open their mouths upward, so as 

 to form denticles on the margins when 

 compressed. Type G. scalaris.
