Actinocamax and Belemnellocamax cephalopods from Sweden

Finishing up my theme of fossils from the Ignaberga, Sweden area are these Belemnites.

This first specimen is Actinocamax (Goniotheutis) quadrata

The second specimen is Belemnellocamax mammillatus

For the life of me I can't tell the two species apart and am going by the labels that were sent with them. Both are from the Campanian stage of the Cretaceous and were sent to me by my friend Christian.
