Zone of Ammonites Buclclandi. — The rocks of this series present 

 the characteristics of the Yorkshire type of the Lima or Buclclandi 

 beds of the south of England, consisting chiefly of shales -with shelly 

 tops and thin earthy limestones, contrasting with the compact blue 

 limestones of the underlying series. The section opposite exhibits 

 the lithological variations of this horizon in the Waterfall Cliff, 

 If allaig, Eaasay. Order ascending. 



The greyish and yellowish- coloured calciferous sandstones which 

 form the remaining portion of the cliff, contain throughout scattered 

 Gryplicm arcuata ; no other fossils observed. 



I place here beds 5 to 11 of Geikie's section, as a few cha- 

 racteristic fossils of this horizon were obtained from beds 5, 6, 8, 

 and 10 ; they are given in the subjoined Table. 



The limestone of Loch Sligachan also belongs here.

Zone of Ammonites Jamesoni. — " The dark grey or brown sandy 

 micaceous shales (with small doggers and shelly masses) of Pabba, 

 beyond Corry, and around the Syenite of Beinn Bhuidh, as far as the 

 entrance to Scalpa Sound " *, most undoubtedly are correlative with 

 the shale occupying the base of Huntcliff, Yorkshire, inasmuch as 

 they contain the same series of fossils, and the other beds regularly 

 superimposed contain identical species each to each. Similar beds 

 are exposed on the banks of the burns by the roadside, two miles 

 from Eaasay House on the way to Hallaig, and elsewhere on the 

 Island of Eaasay.
