Confirming Corydoras species

[Coreador]

Hello~ I’d like to confirm the 3 Corys in the pics. 2 of them were sold as Corydoras Jullii (but i wonder if they are Trilineatus [false Jullii]).
There is a 3rd pic that includes a fish sold to me as Corydoras Adolfoi. Sorry that resolution isn’t great. Just want to confirm that is what they are. Thanks.

These are

Corydoras trilineatus

and

Corydoras adolfoi

, I hope you don't mind me pointing out that they are poorly suited to a gravel bottomed tank.

Thanks! No don’t mind, I’m about to post a question on sand substrates for them. About to change out some of the gravel for sand.
