Shell ovate, thorny, with two distinct strictures. Length of the three joints = 2:5:5, breadth 

 = 3:8:9. Cephalis subspherical, with a large conical horn, which is half as long as the shell, and 

 spirally dentated in the distal half. Thorax conical, spinulate, with regular, circular, quincuncial 

 pores. Abdomen tuberculate, with a small number of very large irregular pores. Feet short, 

 shovel-shaped, nearly vertical, as long as the cephalis. 



Dimensions. — Length of the three joints, a 0-02, b 0-05, c 0-05 ; breadth, a O'OS, b 0-08, c 0-09. 



Habitat. — Fossil in Barbados. 



43. Podocyrtis sphcerogaster, n. sp. 



Shell inversely ovate, with two deep strictures. Length of the three joints = 1:2:6, breadth 

 = 2:4:7. Cephalis hemispherical, with a slender, slightly bent horn, as long as the abdomen. 

 Thorax hemispherical, spinulate. Abdomen nearly spherical, with much constricted mouth. Pores 

 subregular, circular, hexagonally framed. Feet slender, cylindro-conical, about as long as the 

 shell, with outer convexity, distinctly convergent.

 sory horn at its base). Thorax hemispherical, with subregular, circular, small, quincuncial pores. 

 Abdomen campanulate, with a small number (about twenty) of very large, irregular, polygonal pores. 

 Feet conical, small, as long as the thorax, slightly convergent or nearly vertical.
