a fauna charactei'istic of the lower part of the Pendleside series, while 

 the Chokier beds contain a fauna and have a lithological character indi- 

 cating higher beds in the Pendleside series, such as are found in thd 

 bullions of Horsebridge Clough and Crimsworth Dean, Pule Hill, River 

 Dane, and various other localities. 



It is interesting to find this fauna present in its proper position iil 

 Western Eui'ope, and the same fauna obtains \\\ the Lower Carboniferous 

 beds of Magdeburg still farther east,^ and still farther east in the Culm 

 of Herborn.^ 



The results of Mr. Tait's collecting are as follows : 



Poolvash, Isle of Man : — 



Black shale interbeddecT with lenticles 

 and hummocks of limestone containing 

 marine fossils, between tide-marks west 

 of the barn at Poolvash Farm. 



(There has been a great deal of lateral 

 thrusting on the shore. These plant-beds 

 should, I believe, rest on the shelly lime- 

 stone.) 



* With reference to these fossils, Mr. 

 Kidstoa says they seem to be the same 

 class of organism as the unknown Pendle 

 Hill (Hook Cliff) fossil (found last year by 

 Mr. Tait), but apparently specifically dis- 

 tinct. I would say they belong to Gop- 

 perts' and Hall's Dictyonenia.
