Hound hemi- spherical hodiea, with flattened irregular base, full hemispherical top or dome, which, along the margin, is distinctly divided into twelve lobes, being quite regular in size and extending fully one- halt the distance from the margin to the center of the dome, where they be- come obHolete, leaving a smootli, slightly depressed, central, circular area, whoHe diameter is about one-half that of the body. The top of the dome is punc- tured by two well-defined circular open- ings, which are situated close together, and at the marftin of the smooth cir- cular area. During growth the dome becomes elevated, and a lower or basal portion becomes developed, extending from the flattened base to the margin of the dome. This lower portion is somewhat irregularly marked by con- centric lines of growth. The sides, be- low the dome, are moderately straight. Type G. ella. Described at the same place, from the Goal Meas.
