 fig. 6. 



Shell spiny, with deep collar stricture. Length of the two joints = 1:5, breadth = 1:4. 

 Cephalis subspherical, thorny, with a conical horn of the same length. Thorax ovate, spiny, with 

 numerous densely-crowded, subregular, circular pores. Mouth about half as broad, constricted, 

 with nine parallel, vertical, slender, conical feet, about as long as the cephalis.

8. Anthocyrtis subglobosa, n. sp. 



Shell spiny, with deep collar stricture. Length of the two joints = 1:7, breadth = 1:7. 

 Cephalis subspherical, with a conical horn twice the length. Thorax nearly spherical, with 

 small and very numerous, regular, circular pores. Mouth only one-third as broad, constricted, with

Shell smooth, with sharp collar stricture. Length of the two joints = 1 : 6, breadth = 1 : 5. 

 Cephalis subspherical, with a conical horn twice the length, nearly hyaline, with very small 

 and scarce pores. Thorax nearly spherical, with regular, circular, quincuncial pores. Mouth only
