secteetetaere we still lack information about the oper- 
culum, radula and soft parts of the genus, but the structure 
of the periostracum, the texture of the shell and the character 
of the lip, which is thin and somewhat expanded, are so like 
those of Parapyrgula that a close relationship is indicated. 
The shell differs from that of the Kainozoic European 
Fossarulus in its thin outer lip and somewhat expanded mouth.

Professor Gregory’s expedition obtained many specimens, 
as already stated, from earth near the N.W. shore of Erh-hai 
molleoted by Dr. Coggin Brown. Among these there are some 
very young shells in which the protoconch is fairly well pre- 
served. It differs considerably from that of the Burmese 
fossil P. minuta, in which the spiral pune is tuberculate 
from its cormmencement. whereas in P. gredleri it has the 
character of a smooth and prominent ridge on the 2nd, 3rd 
and 4th whorls. The ecteus apex is missing in all the speci- 
mens. 
The periostracum is of a pale green colour, thin but 
thrown into characteristic vertical folds, especially over the 
prominent parts of the seulptur
