nature of the material, did not reveal it. The depth, from the surface 

 to the roof of the chamber, is bh feet. The width of the exposed 

 entrance is 5 feet, and, at 5 feet inwards, it increases to 6 feet, and 

 gradually narrows to a couple of feet at the extreme end. The floor 

 of the fallen-in portion is covered with several tons of earth, but at 

 5 feet inwards it is 5 feet high, and the roof gradually lowers to 

 2^ feet at 1 foot from the extreme end. The total length is 12 feet. 

 The other passage is 4 feet wide and 4 feet long, and is also full 

 of fallen earth. The larger opening lies in a north-west and soutli- 

 east direction, and the smaller chamber trends more to the north. 

 That two passage chambers should lie so close together, ending in 

 the rampart wall, is curious, and I cannot recall another like it. 



LiSNAGALLAUN (O.S. 65). — In the townland of Shanacloon Upper, 

 about half a mile south-east of the village of Kilgobnet, on Sullivan's 

 farm, is the fine rath named Lisnagallaun on the Ordnance map. It 

 has triple ramparts, the inner and outer, however, being very much 

 defaced. The diameter of the rath is 100 feet, and, from the top of 

 the inner to the top of the second rampart, is 24 feet, the thickness 

 of the ramparts being 13^ feet and 15 feet, respectively, and the 

 depth of the trench between is 11 feet. From the centre of the 

 second rampart to that of the third is 20 feet, and the depth of the 

 fosse between is 9 feet. The whole structure must have formed, 

 originally, a fine work of defence. In the south-west side of the 

 rampart a breach, made in hunting after rabbits, disclosed an 

 entrance to a souterrain, which we examined (Plate L). The 

 entrance from within the rath was sought for, and, after a couple of 

 hours search and digging, it was found, at a depth of several feet, and 

 cleared out. The structure consists of a triple chamber, and small 

 connecting passages. Entering, from within the rath, is a chamber 

 14^ feet long, and 2 feet 5 inches wide at the opening, but which 

 gradually widens to 3 feet. The side walls slope inwards, measuring 

 2 feet 4 inches apart beneath the roof, which consists of four great 

 slabs. The chamber has a nearly uniform height of 5 feet, and 

 is well built of ordinary field stones. The walls round off at the end 

 to a low, well-laid passage, 2 feet high, 1 foot 4 inches broad, and 

 2 feet long, formed by two single side stones and one top slab. This 

 opens into another passage, at right angles to the first, measuring 

 10 feet long, 3^ feet wide, and 5^ feet high. The walls slope 

 inwards, and it is roofed by four slabs. Two feet from the north 

 end is another passage, running to the west, similar to the first, 

 measuring 2 feet long, H feet wide, and 2 feet high, formed also by
