1. Patagospyris confluens, Haeckel.
Shell tuberculate, with distinct sagittal and collar strictures. Pores irregular, roundish. Cephalis nut-shaped, larger than the short truncate thorax. Horn conical, shorter than the cephalis.

Dimensions.—Cephalis 0.05 long, 0.07 broad; thorax 0.03 long, 0.07 broad.
Habitat.—Fossil in Barbadoes.
2. Patagospyris lanceolata, n. sp.
Shell tuberculate, with slight sagittal and sharp collar strictures. Pores subregular, circular. Cephalis subspherical, about as large as the truncate subcylindrical thorax. Horn spindle-shaped, about as long as the cephalis. Peristome with a coronet of fifteen to twenty divergent lanceolate lamellar feet, longer than the thorax.
Dimensions.—Cephalis 0.08 long, 0.09 broad; thorax 0.07 long, 0.07 broad.
Habitat.—Fossil in Barbados.
3. Patagospyris stiligera, Haeckel.
Shell smooth, hyaline, with deep sagittal and collar strictures. Pores very small and few. Cephalis nut-shaped, bilobed, of the same breadth as the cylindrical thorax. Horn conical, about as long as the cephalis. Peristome with a coronet of six to nine broad lamellar feet (in Ehrenberg's figure broken off).
Dimensions.—Cephalis 0.04 to 0.05 diameter; thorax 0.06 long, 0.05 broad.
Habitat.—Fossil in Barbados.
4. Patagospyris anthocyrtis, n. sp. (Pl. 95, fig. 19).
Shell smooth, with deep sagittal and deep collar strictures. Pores irregular, roundish, of various sizes, numerous. Cephalis nut-shaped, with two inflated bosoms, about twice as broad as the short cylindrical thorax. Horn stout, pyramidal, about as long as the cephalis. Peristome with a coronet of fifteen to twenty parallel and vertical triangular lamellar feet, nearly as long as the thorax.
Dimensions.—Cephalis 0.05 long, 0.1 broad; thorax 0.04 long, 0.06 broad.
Habitat.—Tropical Atlantic, Station 347, depth 2250 fathoms.
