The genus and species ‘Apractocleidus teretipes‘ was erected by Smellie (1916) for a specimen now regarded as old-adult individual of Cryptoclidus. The specimen was collected by Alfred Leeds and acquired by the Hunterian Museum, Glasgow. The taxon ‘Apractocleidus‘ is therefore considered a junior synonym of Cryptoclidus.

The holotype and only specimen is mounted on display in the Hunterian Museum, Glasgow. In 2011 it was conserved, moved, and remounted by Nigel Larkin.
