of Sardinia. Occasionally the corridor-tomb has a kind of portico at its
west end.

In Munster the corridor-tomb takes a peculiar form (Fig. 7). It lies
roughly east and west, and its two long sides are placed at a slight
angle to one another in such a way that the west end is broader than the
east. In a good example of this at Keamcorravooly, County Cork, there
are two large capstones and the walls consist of double rows of slabs,
the outer being still beneath the cover-slabs. On the upper surface of
the covers are several small cup-shaped hollows, some of which at least
have been produced artificially.

These wedge-shaped structures are of remarkable interest, for exactly
the same broadening of the west end is found in Scandinavia, in the
_Hünenbetter_ of Holland, in the corridor-tombs of Portugal, and in the
dolmens of the Deccan in India.

In some Irish tombs the corridor leads to a well-defined chamber. In a
curious tomb at Carrickard, Sligo, the chamber was rectangular and lay
across the end of the corridor in such a way as to form a T. The whole
seems to have been covered with an oval mound. In another at Highwood in
the same county a long corridor joins two small circular chambers, the
total length being 44 feet. The corridor was once divided into four
sections by cross-slabs. The cairn which covered this tomb was
triangular in form.

In the county of Meath, in the parish of Lough Crew, is a remarkable
