About 30mm long. Possibly Cryptops parisi ?
No interactions present.
Jon, I think you are right with Cryptops - 21 pairs of legs and antennae no longer then 1/4 of body. The more common species is Cryptops hortensis but I'm not sure how you tell them apart.

There is an AIDGAP guide. According to that parisi is slightly bigger (>30mm) than hortensis (<30mm) and my specimen is >30mm. Also it seems to have paired sutures on the segment behind the head but I'm not sure about this feature. I'm hoping a centipede expert spots my post!
The lack of a 'X' sutures on first tergite will rule out C.anomolans, but not clear from this image. A photo of side view of last leg to show tarsal and tibial combs (black 'teeth')would be useful, but I guess the specimen has been long released. They are fused into continuous ridge in parisi, but widely spaced in hortensis. (First impression - looks like parisi, but I'll think about it)

There do seem to be a pair of sutures on the head (but I can't tell how far they extend forwards) so it is NOT C. hortensis (large size is also a clue). There seems to be a 'dip' at the centre of the first tergite, which may be the cross-over of the 'X' suture seen in C.anomalans (which is recessed). Andy Keay has a superb image of this 'X' suture at http://www.ispot.org.uk/node/112176. However, with this specimen I really can't see enough detail to be certain. All three can be found in man-made habitats in southern England. The best I can suggest is Cryptops sp. if jonmortin wishes to enter an ID.
I have had another look at the specimen and tried to photograph the tibial and tarsal combs (not easy with my camera) and the head and first body segment. It's looking more and more like C.parisi to me.
Thanks for adding these images. They do help. It's just possible to make out the 'touching' teeth of the 'ridge-like' tarsal comb (diagnostic of C.parisi), and the closely set teeth of the tibial comb (which is similar in C.anomalans). I would agree if Cryptops parisi was entered as a likley id .
Thanks for that Steve.
