Ceratium pavillardi v. Ceratium vultur japonicum
This is a good example of this species. "Epitheca almost triangular, tapering to a straight apical horn; hypotheca with base sharply at an angle to longitudinal axis." (See Dodge in Taxonomic References.) One antapical horn bends sharply forward and the second apical horn curves backward and then forward. Body length averages 80-100µ. Posterior view on right.
