The shell is rounded at the posterior end, inflated, smooth, narrowly gaping ventrally, with a sharp mid-valve keel producing a flattened ventral surface. The shell is variably banded with dark-brown-and-cream "zebra" markings. Grows to about 2 in (5 cm) in length. Has an internal shelflike septum at the umbo for muscle attachment. Soft body with short, separated siphons; produces byssal threads that exit the shell at a ventral byssal gape.
