This trochiform species reaches about 4 mm in length and often has part of the last whorl disjunct. It is sculptured with distinct axial riblets and has a prominent umbilicus. It occurs with J. edgbastonensis and differs from that species in the sculpture, in having a wider umbilicus and a shorter spire.
