This species is rather scarce along the California coast, being taken 
chiefly in deep water. It reaches a larger size than either P. verticalis 
or P. cenosus.

Habitat.—Coast of California, in deep water. 
This species agrees in habits and general characters with Pileuro- 
nichthys decurrens.

rocks from Alaska southward, being most common about Puget Sound.
