Perhaps you should try some spelling variations:
"sub specie aeternitatis" » "sub speci aeternitatis"
"sub species aeternitatis" » "sub specis aeternitatis"
"sub specimen aeternitatis" » "sub specimens aeternitatis"
"sub specic aeternitatis" » "sub speci aeternitatis", "sub specific aeternitatis"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((((("sub specie aeternitatis") OR ("sub specimen aeternitatis"))) or ("sub specic aeternitatis"))) or ("sub species aeternitatis"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((((("sub specie aeternitatis") OR ("sub specimen aeternitatis"))) OR ("sub specic aeternitatis"))) OR ("sub species aeternitatis")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"sub specie aeternitatis\") OR (\"sub specimen aeternitatis\"))) or (\"sub specic aeternitatis\"))) or (\"sub species aeternitatis\"))".
• Removing quotes may allow a broader search: (((((( sub specie aeternitatis ) OR ( sub specimen aeternitatis ))) or ( sub specic aeternitatis ))) or ( sub species aeternitatis )).
• Adding a wildcard symbol may retrieve word variants: (((((("sub specie aeternitatis") OR ("sub specimen aeternitatis"))) or ("sub specic aeternitatis"))) or ("sub species aeternitatis"))*.
