Habitat.—Mediterranean, surface, Portofino near Genoa, Haeckel.
11. Druppula oliva, n. sp.
Cortical shell thick walled, rough, with irregular network; proportion of the axes = 5 : 4. Pores irregular, roundish, three to four times as broad as the bars; lobed or composed of several conjugated porules (as in Lithapium halicapsa, Pl. [14], fig. 8); five to six large pores on the half equator. Medullary shell ellipsoidal, about one-third as broad as the cortical shell.
Dimensions.—Major axis of the cortical shell 0.15, minor 0.12; pores 0.02 to 0.03, bars 0.007; diameter of the medullary shell 0.04.
Habitat.—Mediterranean (Corfu), Canary Islands (Lanzerote), Haeckel.
Genus 132. Druppocarpus,[[171]] n. gen.
Definition.—Druppulida with simple ellipsoidal cortical shell and simple medullary shell, with numerous radial spines, without polar tubes.
The genus Druppocarpus differs from Druppula only in the radial spines, which arise between the pores of the cortical shell, and therefore exhibits the same relation to it that Ellipsidium bears to Cenellipsis, or Prunocarpus to Prunulum.
Subgenus 1. Druppocarpetta, Haeckel.
Definition.—Network of the cortical shell regular, with meshes of equal size and similar form.
