Fig. 12. Lecanocrinus Lecanocrinidae with rays in contact except at anal side. Crown short and ovoid, main expansion in zone of radials; calyx well differentiated. Infrabasals usually more or less erect forming part of the calyx wall. Radianal rhombic, obliquely to lower left of right posterior radial, resting on basals, not touching right anterior radial. Anal x alone, filling posterior interradius; no inter- brachials in other areas. Primibrachs two, exceptionally one. Arms dichoto- mous, interlocking. Column not enlarging proximally, or but little; columnals usually alternating from the top, becoming uniform farther
