In my RIC its #166 AFAIR ( the book is in storage).
Why the seafaring owl ? Because of the rostral capital ,and the owl standing on the rostrum or prow.
IMHO, one should use the new
RIC reference numbers, especially if the coin is going in the BOT
gallery, otherwise it causes confusion.
Wildwinds and my
Forvm gallery (for silver) have the updated
RIC numbers if you're missing the new edition.
Many of the older references mistakenly call it a prow too. Interestingly enough, the new
RIC notes
Oxford has an example of this 730
type depicting an actual prow instead of the normal
columna rostrata.
