embedded in a yellow dolomitic matrix. These layers coutaiu 

 forms identical with those found in the algal layer lying at the 

 base of the Prochictus-glohosus Band iu the Shap and liavenstone- 

 dale Districts, and undoubtedly represent the same horizon. About 

 30 feet above the base occurs a compact, porcellanous, grey lime- 

 stone, containing crushed and recrystallized crinoid-stems, together 

 with teased-out corallites of Syrincjopora. In the succeeding 40 

 or 50 feet fossils are scarce, with the exception of Semimda aff. 

 Jicoidea and S. gregaria. One or two thin black shaly layers,, 

 however, occur containing plant-remains, among which fragments 

 referable to ArcJiceosigiUaria vanuxemi Goppert may be recognized.^ 



In the upper portion of the cliff, silicitied fragments of a small 

 Cyrtina (aff. carhonaria) occur; these are in too fragmentary a 

 condition for exact determination, but the form is not unfrequentiy 

 met with at this horizon in the Western Districts. The Thi/sano- 

 lyhyllum-jjseudovermiculare Band has almost died out here, though 

 one or two corallites, referable to this species, have been collected 

 about 40 feet below the summit of the section.- About 30 feet belov.^ 

 the top of the cliff the beds become rather more fossiliferous, and in 

 addition to Semimda at least two species of Sgringojjora occur in 

 some profusion. 



The following species have been collected from the Semimda- 

 ffregaria Sub-zone at Meathop, up to the base of the Sjnri/er- 

 fiircatus Band : —

This assemblage, although containing several new species, 

 agrees with the fauna of the Seminida-gregaria Sub-zone of the- 

 Shap District, while the Algal Layer, which is so well developed 

 along the bottom of the cliff, may be taken, here as elsewhere, 

 to represent the base of the sub-zone. The Brownber Pebble-Bed 

 has entirely thinned out here, and the Thysanophyllum Band is 

 scarcely represented ; but the dolomitic character of the rock and 

 the abundance of S. gregaria and S. aii'. Jicoidea, taken together with 

 the fact that the beds are underlain by the Camarotcechia-proava 

 Band and overlain by the Sjnrifer-ct furcatus Band, leaves no

 horizon in Kavenstonedale, mentioned on p. 500.
