Pyrgulopsis brandi (Drake)

Brand’s Pyrg (Pyrgulopsis brandi)

Brand’s Pyrg was described in 1953, it was endemic to the thermal springs at las Palomas in Chihuahua, Mexico.

The springs at Las Palomas dried out in the 1970s, leading to the extinction of the endmic molusc fauna, inluding this species. [1]
