Having hand-like fins or wings; characterized by structures resembling bat wings or modified hand appendages.
From 'chiropterygian' with the suffix '-ous' (full of or characterized by), or independently from Greek roots meaning 'hand-winged.' This is an extremely rare variant of older zoological terminology.
Some words are so obscure they might exist in only a few old encyclopedias—'chiropterygious' might be one of them, representing a failed attempt to describe fish or creatures with hand-like fins!
