Holospira

See text Holospira is a genus of air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Urocoptidae.

The shell is small, cylindric, terminating above in a conic spire, retaining all the whorls, rimate or perforate.

Kidney is very narrowly triangular, being wider at the base, tapering anteriorly, slightly longer than the pericardium.

[2] The radula is about four times as long as wide, with from 19.1.19 teeth (in Holospira pilsbryi) to 27.1.27 (in Holopsira nelsoni).

[2] The free retractor muscles, attached proximally to the axis at about the junction of the cone with the cylindrical portion of the shell, are excessively long.
