What is the name of this check mate trap?

I set up a check mate (I have been trying to set this one up for ages, and I sort of accidentally stumbled into it in this game.) Afterward my opponent and I were discussing it and I could not recall the name.

It's called Legall's Mate

Thanks. It's been bothering me. Seems legall's mate is a tad different. It uses the other knight instead of the opponents pawn, but it's the same idea. In either case, it is the mate trap I had in mind, but couldn't remember. Thanks again.

I don't believe it has a name. It's similar to a semi-smothered mate, but a semi-smothered mate is delivered by the knight, not the bishop.

Here's an old OTB game of mine from the 1970s (!). It was an off-hand game, not tournament.
