The Irish Naturalist. 



July, 1905. 



entomologists reported the Red Admiral and Orange-tip butterflies, 

 while one member obtained a small but perfect wasp's nest. The 

 botanists were also very busy, being stimulated by the offer of a book 

 prize by the President for the best collection of wild flowers. This was 

 won by Miss Ella Boyd, of the Dungannon Club, whose vasculum con- 

 tained eighty species of plants. The best find of the day was Ranuncultis 

 tricJiophyllus, whicli has only been recorded from County Tyrone on one 

 previous occasion. 



May 27. — The Geological Section held an excursion to Cave Hill and 

 Carr's Glen. The party proceeded from Castle Junction by tram to the 

 foot of Cavehill Road, at which point they were met by a further detach- 

 ment of members and friends. 



On reaching the Cave Hill quarries Mr. Gray drew particular attention 

 to the missing Oolitic formations which should occur between the 

 Rhaetic (Lower Jurassic) and the Greensand (Upper Cretaceous) forma- 

 tions, representing a gap of about 5,000 feet. This feature shows that at 

 a period between Lower Jurassic and Upper Cretaceous times the region 

 had been elevated above sea level, with the result that great masses of 

 the strata had been stripped from the land. 



A few of the members proceeded to Carr's Glen to work at the Lias, 

 but several returned to town, as after the heavy rains the glen was not 

 in good order for geologising. The find of fossils was not large, the 

 specimens recorded being Exogyra cojiua var. /avigafa, Belemnites ultimus, 

 Belenmitella niucronata, Echinocorys vulgaris, Rhychonella limbata^ spines of 

 Cidaris, and Cardinia ovalis.
