HELP - Have I got some sort of sump plug missing?? URGENT

I am in the process of doing some work on our 1994 Discovery 300Tdi and noticed when draining the oil that the car appears to have a sump plug missing from the bottom of the bellhousing of the gearbox.

That's what I think it is anyway...

Ive had a look in Haynes and the images in that look v different to what I'm seeing (in terms of me thinking its the drain plug for the gearbox oil).

Can someone please take a look here and let me know what it is I am missing?

Sorry they're upside down. The oil sump is seen in the pic for a reference point.

I imagine whatever I am missing needs fixing urgently! So quick responses much appreciated!

BTW tried the engine oil sump plug/bolt and that fits it ok...

Thank you

Tis just a wading plug mate, only really needed if your going wading so don't worry, best left out on dry roads anyway.

Fantastic panic over!

Thought my gearbox was potentially running dry!

Thanks
