Indeterminable fragments of fishes were also found in small 

 nodules of clay-ironstone from this horizon at the Tunnel, Biuley, 

 and Kingsbury Collieries.

This horizon was seen at Amington Colliery, where the fisb- 

 remains are found, in association with Carhonicola^ Spirorbis, and 

 ostracoda, in a black shale said to come from the Double Coal. 



It is interesting to notice the varied habitat of these ubiquitous 

 organisms, Spirorbis and ostracoda. They occur in the Middle 

 Coal Measures associated with freshwater shells, such as Carbonicola 

 and its allies ; but they are equally common in the marine shales, 

 where the shells of Fterinopecten are frequently covered with the 

 casts of Spirorbis. In the upper beds of the Productive Measures, 

 where mollusca appear to be absent, Spirorbis is found adherent 

 to the stems of Ccdamites goepperti. These fossils are still more 

 abundant in the Upper Coal Measures, but they appear to be 

 restricted to the Spirorbis Limestones. The Spirorbis Limestone 

 in the ISTuneaton Clays is crowded with Sp>iro)'bis and ostracoda : 

 they are common in the limestones in the Haunchwood Sandstones 

 and persist into the Keele Beds ; but they finally die out in the 

 thin and almost unfossiliferous limestone near the top of the Keele 

 Beds. 



Finally, the following fossils are mentioned in this brief summary 

 of the fauna, because of their great rarity : —
