This is puzzling and highly doubtful for two reasons:
(1) P. dubius was only described 6 years later by Bleeker in 1852 (see e.g. Wueringer2009 ref + Van Oljen, Faria & McDavitt, 2007. The curious holotype of Pristis dubius Bleeker, 1852 and the unravelling of Bleeker's sawfish taxonomy. Raffles Bulletin of Zoology 14).
(2) P. dubius is not recognized as a valid species by recent authorities (see refs listed in #1). -->|image=Pristis pristis - Georgia Aquarium Jan 2006.jpg|image2=Sawfish Pristis zijsron Genova Aquarium.jpg|image2_caption=[[Hiu gergaji umum]], ''Pristis pristis'' (atas),<br/> [[Ikan gergaji hijau]], ''Pristis zijsron'' (bawah)|taxon=Pristidae|authority=[[Charles Lucien Bonaparte|Bonaparte]], 1838|subdivision_ranks=Genus|subdivision=*''[[Anoxypristis]]'' <small>[[Errol White|White]] & [[J.
