Purl in the round

Okay so I’m trying to do this pattern:

It calls to knit a round purl a round. Whenever I do the purl round I keep getting doing a yarn over. How do i bring my yarn to the front without doing the yarn over?

It’s pretty much the same as switching between knit and purl in the middle of a row, if you’ve done that – you just bring the working yarn between the needles, after you finish the last knit stitch and before you start the first purl stitch, rather than over them.
