Dr. B. F. Schar/f, etc. — JSa'jiloration of Resh Caves. 505 



(after the Alpine traveller, John Ball, F.R.S.), twenty-three miles 

 distant from Field, Mr. Whymper discovered the same Trilobite- and 

 Molluscan-bearing beds. 



In addition to the Trilobltes, etc., Mr. Whymper obtained good 

 examples of Anomalocaris Canadensis, a remarkable phyllocarid 

 Crustacean, described by Dr. J. F. Whiteaves, F.G.S., the Palaeon- 

 tologist to the Geological Survey of Canada. 



Mount Field, which faces Mount Stephen, remains still unexplored, 

 but is a part of the same massif, and will no doubt yield the same 

 ■Cambrian fossils. It is only separated from its brother peak by the 

 present pass, which glacial torrents working for long centuries have 

 gradually widened into the existing river valley.

VIII. — The Exploration of Kesh Caves, County Sligo, Ireland. 

 By Dr. R. F. Schabff, B.Sc, F.Z.S., and others. i 



KESH, or as it is locally spelled ' Keash,' is fifteen miles south of 

 the town of Sligo, and consists of a few scattered buildings, 

 with farms about them. The spot is at the foot of Keishcorran 

 Mountain, an isolated mass of Carboniferous Limestone which rises 

 to 1,183 feet ; and the country which extends south and west from 

 this mountain for miles from Kesh presents an array of gravel 

 eskers and elongated mounds of glacial material, with here and 

 there a small lake or marsh in the hollows between them. 

 Sprinklings of erratic boulders and stones occur up to the very 

 summit of the mountain. These consist principally of red sand- 

 stone, with a few of yellow sandstone and of dyke rocks. It is 

 believed that these rocks could be found in place on the next hill 

 range to the south and south-east of Kesh, around Lough Key, but 

 this point has not been definitely established. Though no continuous 

 deposit of drift was seen on the mountain, these erratic blocks are 

 sufficient to show that it has been overwhelmed by ice. 



On approaching Keishcorran from Kesh one sees a grass-grown 

 talus which extends up from the plain at a steep angle for several 

 hundred feet. Surmounting this is a range of cliffs running along 

 the mountain face like the gigantic walls of an ancient city. These 

 are pierced along the top of the talus by a range of some thirteen 

 caves. Towards the northern end of this series is a cavern whose 

 large orifices, about fifteen feet high, can be seen for miles. The 

 other caves are of various sizes, but the type which prevails is that 

 of a vertical fissure enlarged downwards into an ' A ' shape. The 

 cliff" which they penetrate faces S.W., or S.W. by W., and their 

 direction is approximately parallel. These caves are intersected at 

 various distances from their mouths by cross-fissures, which in
