iS96.] Jameson. — Caves of EnnisJdllc7i and Mitchcls town. 95 



bourhood could occupy but a small part of the vast capacity of 

 this cave, which is in places fully forty feet high, and fifteen or 

 twenty feet wide. Unfortunately a couple of hundred yards 

 from the entrance further progress was prevented by a heap of 

 fallen debris which completely blocked the way. At the 

 inner end of the passage, where the heap of boulders stopped 

 us, was a burrow, possibly belonging to a Badger, and Mr. 

 Knight's dogs which had accompanied us showed by their ex- 

 citement that the animal was within. This further supports 

 my belief that this cave is in great part dry at all seasons. 



The Invertebrates I found here are all species which occur 

 above ground; they are — a spider, Porrhovia viicrophthahna, 

 which Mr. Carpenter tells me has been found in a coal-pit, 

 occurring also above ground ; Brachydesmus siiperus, a blind mil- 

 lipede, which also occurs above ground ; luhcs pilosics, a 

 typical millipede ; Tomocerus tridentiferus, a collembolan, found 

 at Mitch elstown by Wright and Haliday ; recorded by Packard 

 from North American caves, occurs under stones above 

 ground •} Velia currcns, the water-bug found at Bohoe ; a 

 fungus-midge, Sciara Tho7ncB ; and four beetles, Bembidium 

 rufesceiis, A7icyrop hones omalimts, Hclodes ma7'oinata, and Co- 

 prophilus striatulus ; the last, Mr. Halbert tells me, ;has not 

 hitherto been recorded as Irish. All these beetles inhabit 

 moist, marshy places, and were probably washed into the cave. 



After leaving Coolarkin cave we visited Bohoe church, 

 where Mr. Knight informed me there was an immense colony of 

 bats. We found a number of j-oung Pipistrelles( Vespertigo pipi- 

 strellus) from a few days old to half-grown individuals, crawling 

 about the floor of the church, having fallen through a hole in 

 the ceiling. There must have been an immense colony in the 

 roof, but unfortunately there was not a ladder at hand to 

 enable me to inspect it. Having collected a number of these 

 young bats I returned to Bnniskillen, as darkness was already 

 coming on. 



On July 12th, next day, I drove to the Marble Arch, at 

 Florence- Court, and, after collecting a few invertebrates about 

 the grounds, I was met by Mr. Bowles, the keeper, who accom- 



^ For this and other information respecting the invertebrates found I 

 am indebted to Mr. Carpenter.
