Original Description
which in late forms tend to be larger near the collar stricture and with their bars joining the cephalis above the level of the collar
pores. The thoracic wall is a thin, porous lamella proximally, becoming much thicker distally where the pore frames are high. Abdomen distinctly more delicate than the thorax, irregularly subcylindrical, often constricted medially; when observed complete, which is rarely, terminated with a thin poreless peristome bearing small teeth. In late forms the row of pores just below the lumbar stricture increase in size to two or three times the size of the surrounding pores.
