at Rosapenna, Bundoran, Strandhill, and Dog's Bay. In early 

 Holocene times and when there was but a small accumulation of 

 sand, these localities must have been covered by a "scrub" 

 growth in which the damp-loving species found congenial en- 

 vironment. The climate was probably warmer and moister, and 

 we may thus correlate these deposits with the warm " Tapes " 

 period of the Scandinavian geologists, which has been shewn to 

 be early Neolithic ; and in Denmark to coincide with the late 

 " Fir " and early " Oak " periods. The recognition of this fact 

 is of the utmost importance in the solution of many post-Glacial 

 problems. a. s. k. 



MYRIOPODA. 



The Myriopoda collected by several members during the 

 Fiftieth Anniversary excursions have been submitted to me. The 

 collections contained several new county records and one variety 

 new to science — securiformis of Polydesmus coriaceus — which I 

 have described elsewhere.* The following list contains particulars 

 of the collections : — 



Chilopoda (Centipedes). 

 Family — Lithobiidae. 

 Lithobius forficatus Lin. Murlough Bay and Fair Head, 



Antrim.

 Kinbane, and Fair Head, Antrim; Benevenagh, Derry. 

 L. melanops Newport. Giant's Causeway, Kinbane, and 



Armoy, Antrim ; Benevenagh, Derry. 

 L. crassipes Koch. Murlough Bay, Antrim, new county
