Perhaps you should try some spelling variations:
"sub specie aeternitatis" » "sub species aeternitatis", "sub spece aeternitatis", "sub specke aeternitatis"
"sub specimen aeternitatis" » "sub specimens aeternitatis", "sub species aeternitatis", "sub specmen aeternitatis", "sub speckmen aeternitatis"
"sub specic aeternitatis" » "sub specific aeternitatis", "sub specc aeternitatis", "sub speckc aeternitatis"
"sub speci aeternitatis" » "sub spec aeternitatis", "sub speck 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 speci 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 speci 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 speci aeternitatis\"))".
• Removing quotes may allow a broader search: (((((( sub specie aeternitatis ) OR ( sub specimen aeternitatis ))) or ( sub specic aeternitatis ))) or ( sub speci aeternitatis )).
• Adding a wildcard symbol may retrieve word variants: (((((("sub specie aeternitatis") OR ("sub specimen aeternitatis"))) or ("sub specic aeternitatis"))) or ("sub speci aeternitatis"))*.
