Backeljaia gigaxii is a species of air-breathing land snail, terrestrial pulmonate gastropod mollusc in the family Geomitridae. [1]
The 5.4-8.1 × 7.4-12.2 mm. shell of this species has, in comparison with Candidula intersecta , whorls that increase more rapidly, the inside of the umbilicus is very narrow, but remarkably wider at last whorl. The shell is light brown or sandy-coloured with pale colour bands. It is usually flatter and larger than the shell of C. intersecta. [2]
