Cephalopoda. 
Glyphioceras micronotum. 
Orthoceras sp. 
Pisces. 
Elonichihys Aitkini. 
Elonichthys sp. 
Crustacea. Not yet identified. 
Number 2 Shaft. — Here there is only a small spoil heap, 
owing to the shaft having filled with water and been 
abandoned. The material is a very fissile black shale, often 
very fossiliferous and containing numerous nodules, rich in well 
preserved fossils. One nodule contained some vegetable tissue 
of which I made microscopic sections, which show the internal 
structure exceedingly well. 
From here I have obtained — 
Cephalopoda. 
Glyphioceras micronotum. 
Orthoceras \ Fragments of large specimens too poor 
Goniatites J to identify. 
Plants. 
Medullosa anglica. 
Number 3 Shaft. — From here the tunnel was driven both 
ways, and the material brought from the northern face was a 
micaceous shale of a fluviatile type, in which I found no marine 
fossils. 
The material from the southern face was a hard blue shale 
often containing small nodules of pyrites in definite bands. 
Here I obtained the following : — 
Brachiopoda. 
Lingula mytiloides. 
Produ^tus (spines). 
Rhynchonella (sp.).
