Cylindroiulus punctatus (Millipede)

Walking through Doonhill Woods,i spotted what looked like a worm on a discarded apple core.
On further inspection i realised it was some sort of millipede.

My book says it's a cylindrosulus punctatus,but there are more internet hits for cylindroiulus punctatus and from more scientific sources,so i'll go with that.
Looks a different colour from the one in my book though.
