Vaquerosella norrisi (Pack, 1909) View in CoL
Description (Pack, 1909). Test sub-circular in general outline. With deep, broad, marginal notches in the edges of the ambulacral areas; the two posterior notches much deeper than the anterior ones, shaping the posterior end of the test into a prominent process. The test when viewed from above has a leaf-like appearance. Test flat with edges markedly thin. Apical system and test apex centrals. Mouth central, slightly sunken; food grooves poorly shown but little branched, continue from the mouth to the margin, entering the marginal notches. Periproct small, inframarginal. Petals strongly raised, extended about three-fourths the distance to the margin and not entirely closed at the ends.
