How to find number of turns in these transformers?

    I am looking for a small transformer with a 1:30 turn ratio. I have found a nice selection of transformers, with the datasheet as follows:

    The problem is, it doesn't appear to list the turns in each coil. I could calculate the turn ratio from the inductance of each coil, but they only give the parallel inductance and series inductance of the two coils.

    How would I go about figuring out the turn ratio using the information from that datasheet? Thanks!

    The two coils have identical windings, the turns ratio is thus 1:1. They are normally used as inductors but can be used as 1:1 transformers.
