Hirasea eutheca Hirase

Straight Hirasea Snail (Hirasea eutheca)

The Straight Hirasea Snail was described in 1907; it is, or maybe was, restricted to the island of Hahajima in the Ogasawara Islands, Japan.

The shells reach sizes of about 0,2 cm in height and about 0,3 cm in diameter; the spire is low-conic and the base very convex.

The species is now likely extinct. [1]
