I've found a few of these on beaches on the Isle of Man. Grateful for any advice.
Thanks

Hello and welcome to the forum. These are pebbles of Carboniferous limestone (300 - 360 million years old) of various sections of a coral called Lithostotion or Syringopoa - I'm not good at working them out!

Colin is right on both counts...The smaller coral is Syringopora and the larger, Lithostrotion
You can find identical pebbles in the glacial debris on the Yorkshire and Lincolnshire coast (and probably all stations between there and Isle of Man).  I'm sure you noticed that when wet, the coral structure is much more apparent.  If you can polish them, this appearance can be restored.

I agree the smaller one is Syringopora. The larger one used to be Lithostrotion but is now called Siphonodendron (or it may be the rather similar Diphyphyllum). 

Lithostrotion is reserved for their cerioid (solid honeycomb structure, not branched) relatives.
