Habitat.—Fossil in Barbados.
Genus 454. Liriospyris,[[72]] Haeckel, 1881, Prodromus, p. 443.
Definition.—Zygospyrida with six basal feet and three coryphal horns.
The genus Liriospyris differs from the preceding Hexaspyris, its ancestral form, in the possession of three coryphal horns (one odd apical in the middle, and two paired frontal horns on each side of it); it therefore bears to the latter the same relation that Triceraspyris does to Tripospyris.
1. Liriospyris hexapoda, n. sp. (Pl. [86], fig. 7).
Shell subspherical, smooth, with slight sagittal stricture and irregular roundish pores; two to three pairs of large annular pores on each side of the stricture. Basal plate with four large collar pores. Three horns and six feet nearly of the same size and of similar form, conical, divergent, about one-third as long as the shell.
Dimensions.—Shell diameter 0.09 to 0.1; horns and feet 0.03 to 0.04 long.
Habitat.—Central Pacific, Stations 265 to 268, depth 2700 to 2900 fathoms.
