Embryology of the New Zealand Onchidiidae and its Bearing on the Classification of the Group

Abstract

THE Onchidiidae are a group of the Gastropoda, possessing both Pulmonate and Opisthobranch characters. This fact has led them to be classified sometimes as Pulmonates and at others as Opisthobranchs. It is rather surprising to find, in a group that could throw some light on the origin of Opisthobranchs and Pulmonates, and the classification of which is debatable, that the embryology of only one species, Onchidella celtica Forbes and Hanley, has been examined. The two papers published on the embryonic development of this species have both resulted in important conclusions being drawn as regards the classification of the Onchidiidae.
