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