Carinated bowl with sloping floor and wide flaring walls, a low, small ring base, and narrow, rounded to outwardly hooked rim with two grooves on inside opposite a exterior molded convexity (like a torus) set off below by a thin bead. Two subtypes; one on average smaller with thinner walls and rouletting (A); and one on average larger and more coarse in formation (B). Very common early ARS form.
Chronology comment
Bonifay (p. 156) prefers to extend the end of 8A into second half of the 2nd century and the end of 8B into the 3rd century.
