This species is more tumid even than A. ascaris, from which 
it differs in being smooth, with a minute apex. A specimen 
from Jaya sand appears exactly like in all particulars ; though, 
with so few characters to judge by in the shell, the animal may 
be distinct. Long. *053,. long. spir. ‘035, lat. °024, div. 27°.

resembling Eu. acuta, Sow. (Proc. Zool. Soc. 1834, p.8; Leios- 
traca a., H. f& A. Ad.: non. Hu. acuta, A. Ad.) but appears 
a genuine Eulima. It is remarkable for the extremely slight 
divergence of the spire, though the whirls are not elongated.
