Perhaps you should try some spelling variations:
"sub specie aeternitatis" » "sub species aeternitatis", "sub specimen aeternitatis", "sub spece aeternitatis", "sub specke aeternitatis"
"sub specic aeternitatis" » "sub specific aeternitatis", "sub specc aeternitatis", "sub speckc aeternitatis"
"sub speckc aeternitatis" » "sub speck 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 specic aeternitatis") OR ("sub speckc aeternitatis"))))) or ("sub speci aeternitatis"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("sub specie aeternitatis") OR ((("sub specic aeternitatis") OR ("sub speckc aeternitatis"))))) OR ("sub speci aeternitatis")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"sub specie aeternitatis\") or (((\"sub specic aeternitatis\") OR (\"sub speckc aeternitatis\"))))) or (\"sub speci aeternitatis\"))".
• Removing quotes may allow a broader search: (((( sub specie aeternitatis ) or ((( sub specic aeternitatis ) OR ( sub speckc aeternitatis ))))) or ( sub speci aeternitatis )).
• Adding a wildcard symbol may retrieve word variants: (((("sub specie aeternitatis") or ((("sub specic aeternitatis") OR ("sub speckc aeternitatis"))))) or ("sub speci aeternitatis"))*.
