The myrosperidan genus Davisia in two deep-sea fishes.

Two new species of Davisia were identified in the urinary bladders and kidney tubules of 2 species of marine fish. D. anoplopoma was found in Anoplopoma fimbria from southern and central California. D. pectoralis was recorded from Coryphaenoides pectoralis from northern California. We have distinguished between Davisia species whose lateral appendages are "solid" and those which contain a cavity in their lateral appendages. Our species belong to the latter category. We believe the lateral appendages of "hollow" species are extensions of the spore body and not, as sometimes pictured, independently attached.
