Abstract: A broad survey of the literature on reptiles and amphibians reveals that the ambiguous term 'ovoviviparity' has been applied to a variety of reproductive patterns that have little in common. Among these are patterns that can more clearly be referred to as aplacental viviparity, oviparous egg-retention, egg-tending, pseudoviviparity, and lecithotrophy. Some of the uses of 'ovoviviparity' are based on invalid assumptions, and some are mutually exclusive; thus, particular care must be used in interpreting literature reports that lack operative definitions. To minimize confusion, future reports and reviews should avoid 'ovoviviparity' in favour of unambiguous alternatives that explicitly distinguish patterns defined on the basis of reproductive products at deposition from patterns based on sources of nutrients for embryonic development.

IMPORTANT NOTE - JUNE 2020

Please note that as from Volume 31 Number 1 (January 2021) on, the Herpetological Journal will be available as an online publication only - the last print edition will be Volume 30 Number 4.   

Aligning with this change, it is now no longer possible to purchase a subscription that includes a print copy of the HJ.  All members who have existing HJ print subscriptions that remain active as at end June 2020 will receive the full four 2020 print editions.  New subscribers or renewals after this time will only have option to subscribe to the online only subscription package.  Subscription pricing has been amended to reflect the content changes.
