L. — This earn, is much iTuned by the depredations of rabbit- hunters. 

 Unlike the other cams, it is abnost entirely overgrown with peat. After 

 several examinations we decided that it would not repay investigation. 



CaERAIG NA HEoRSA (" CaRRICKSAHOENA ") TO'WTvLAND. 



M. — A small dilapidated earn iiiined to the base, which consists of standing 

 stones about 3 feet high. The diameter is 25 feet : at the north-east face is a 

 passage 10 feet in length, leading to a cist 4- feet square, with two cellae. at the 

 side and one at the back. It was e^idently a cruciform structure like G and 

 K, but of much smaller size. 



X. — Is similar to M, and in similar condition. It was about 20 feet in 

 diameter. Thi-ee jamb-stones remain on the east side of the entrance, which 

 faced the north. The chamber seems to have been cruciform. It is probable 

 that the stones which oi-iginally covered these two cams were removed for 

 building boimdaiy walls. 



Dux XA BHFiOKADH (" DOOXAVEERAGH ") TOWNLAND. 



0. — A small earn, about 17 feet high and 58 feet in diameter at base, roughly 

 built of stones rather larger than are used elsewhere in the series. Near the 

 top, on the southern side, was a small pentagonal cist, about 3 feet 6 inches 

 high and 4 feet in maximum length, covered with a single slab of stone. It 

 was entered thi'ough an opening 10 inches wide from a manhole, also 

 pentagonal, and covered with two slabs. The floor of the cist was quite 

 irregular and was heaped up with discs of sandstone, bone, and ashes. The 

 height is given on the 0. S. map as 890 feet above sea-level. A plan and 

 section of the earn, with an enlarged plan of the cist, are shown on Plate XXII ; 

 and Plate XY, fig. 4, shows the top of the manhole and the narrow entrance 

 into the cist. 



P. — A beautifully built conical cam, about 12 feet high, and 33 feet in 

 diameter at the base. The Ordnance map gives 138 feet as its height above 

 sea-level. The most careful examination of this earn failed to reveal any 

 cist, chamber, or iateiment; it is a cenotaph, hke Cam A. Four large 

 boulders of rock had been laid on the site chosen for the cam, and the stones 

 were heaped on these. 



II. Dolmens. 



1. A short distance south-east of Cam H is a massive block of Limestone 

 which, when sound, measured about 5 feet 7 inches by 4 feet by 1 foot 

 8 inches. It is now split into fragments. It had been placed on four 

 round boulders of sandstone, now partly buried in the peat, which were
