New York: McGraw-Hill Book Company, 1967. - 792 p.This is Volume VI (the last one) of a 6-volume monograph treatise on the invertebrate metazoans. Volume VI deals with Aplacophora, Monoplacophora, Polyplacophora and Gastropoda. Unfortunately, due to her old age, Dr. Hyman was unable to complete her magnum opus, and hence the treatise ends here. A thorough academic classic in invertebrate zoology.
