About Backeljaia gigaxii (L.Pfeiffer, 1847)
The shell of Backeljaia gigaxii measures 5.4–8.1 mm in one dimension and 7.4–12.2 mm in another. Compared to the shell of Candidula intersecta, the whorls of Backeljaia gigaxii increase in size more rapidly. The interior of its umbilicus is very narrow, but it becomes noticeably wider at the last whorl. The shell is light brown or sandy in color, and marked with pale color bands. It is usually flatter and larger than the shell of C. intersecta. This species has been recorded in multiple Western European countries and islands: Great Britain, Ireland, France, Italy, Belgium, Netherlands, Germany, and Spain.
