Metal one is in full view as Symon says, one with the bare filter element is also in the engine bay but is under the engine cover inside a metal domed fitting that has to be removed and dismantled to change the element. My daughter's Fiat 500 manual showed something similar, one was an element and the canister top had to be unscrewed to replace, other was a complete metal canister replaced in one go. Depended on which Euro spec the engine was. The oil filter was the same, a choice of two entirely different types.
It is one or the other, not both. French cars were notorious for having two different options for brakes, alternator, starter motor etc. You needed to know which was used before buying as although it should have been a 50-50 chance it wasn't, invariably it was the wrong one. Believe it was all to do with ensuring supply of components in the event of a hiccup.
