Two Crosses symbol in pattern Pauline Turner book What does it mean ?????

In the book How to Crochet by Pauline Turner in a pattern are two symbols which look like two crosses. What does it mean ?????
I get it it is suppose to mean go back to that same two symbols and repeat but I don't see the symbols earlier in the pattern.

It says "(two crosses symbols) rep from * twice more.
The two crosses symbols do NOT appear earlier in the pattern.

Is this a Britiush symbol?

Forums: 

Can you post all of that particular row or round instruction?

And if you think these symbols are short-hand for something, have you looked through the rest of the book to see if there is an explanation of the symbols used?

I'm attaching a link, showing pictures of various Crochet Stitches and what they stand for:

Hope this helps!
