Note. — We hope to have an earJy opportunity of describing and figuring the new 

 species. 



Of this list 24 species occur elsewhere in the Carboniferous rocks 

 of the North of England. And 28 of them are known to us from 

 Scotland. Two others {Cytherella? reticulosa and Bairdia legumen) 

 are also probably found there. Five species — Leperditia obesa, 

 Kirlcbija tricoUina, Phreatura concinna, Xestoleberis f subcorbuloides, 

 and Cythere? gyripunctata — are new to us.
