IV.—Cromlechau.

A double Cromlech [Ty Newydd Burial Chamber [Map]],—Close to the house of Trefor, on the road from Beaumaris to Pentraeth, in a field on the south side of the road. They were erect not many years since, but were then thrown down by the tenant, because they were superstitious. (For "they were," read, "he was.")

A double Cromlech [Plas Newydd Burial Chamber [Map]],—In the park of Plas Newydd. This has been often engraved and described. (See Pennants' Tour in Wales; Journal of the Archaeological Institute, &c.) Traces of the carnedd of stones which once covered it are still visible.

Cromlech [Bryn Celli Ddu Burial Mound [Map]],—With passage of stones covered over, at Bryn Celli du, near Plas Newydd. This has been fully described and illustrated in the Archaologia Cambrensis? It is styled Yr Ogof, or the Cave, on the Ordnance map, from its having been always considered so until the superincumbent carnedd was removed. It is now securely fenced off, and preserved from future injury, by the care of C. Evans, Esq., of Plas Gwyn, acting on behalf of the Marquis of Anglesey. This is almost an unique instance of the kind in Wales.

Cromlech,—Near Llanidan Old Church, to the south-west ; it is partly thrown down. Cromlech,

At Bodowyr [Bodowyr Burial Chamber [Map]], near Llangaffo. This is one of the smallest cromlechau known, and is in admirable preservation. (See Journal of the British Archaeological Association.)
