are attached, not to the foot, as in ornata, tod to the interior of 
the case, which is thus seen to he very thin. The development

EXPLANATION OF THE ILLUSTRATIONS. 
Plate ix., fig. 1, represents an adult Floscularia ornata, viewed from 
behind, magnified two hundred diameters. Eggs in various stages of maturity 
are seen clustered around the foot, and one egg-shell, from which the young 
has escaped. Fig. 2 is a young one soon after birth ; and fig. 3, one farther 
advanced. 
Fig. 4 represents the disk and upper portion of an adult F. campanulata, 
viewed from behind ; and fig. 5, the young half-grown, of the same. 
Fig. 6 represents the disk and upper portion of an adult F. cornuta, viewed 
sidewise. All the figures are taken from the life.
