It's OK, it's not a snake.
Whilst adding the above Slow Worm on irecord I received a notification that the record was from outside the known distribution for the species. A look on the NBN database showed no records for Slow Worm, Common Lizard, Adder and Grass Snake for Merthyr Tydfil CBC! And only Grass Snake appears to be recorded from the Cynon Valley! I've already submitted two records for Common Lizard (Mike, one was by the climbing centre). Another reminder to all to add the records of all species via SewbRECORD or irecord and fill in the gaps in the records.
