Make 1 pearl stitch

Does anyone know if the make 1 pearl stitch is the same as make 1 rt? I’m working on a pattern from Berroco-- http://www.berroco.com/exclusives/tonia/tonia.html-- and it calls for a M1P stitch. The only problem is that I’ve never seen any tutorials for this M1p stitch and when I do it according to Berroco’s definitiion, I end up getting holes in the pattern.

What am I doing wrong?

It’s make 1 purlwise, exactly the same as a m1 but you purl into it instead of knit.
