All other syntypes of a taxon for which a lectotype is designated become 
paralectotypes regardless of whether or not they are listed in the lectotype 
designation. If you can show that the fourth specimen was a syntype (ie. 
examined by the taxon author before he described it and not specifically 
excluded from the type series in the original description) then it also has 
paralectotype status.

I assume that you have already checked the original description to see how 
many type specimens are listed there, if there is such a listing. Many older 
descriptions do not state the number of specimens in the type series, but it 
is likely that the fourth specimen with a similar label was a syntype.
