 ferent stages of growth. 



Ficf. 2. Transverse section of another example of the same, Lower Car- 

 boniferous, Brockley, near Lesmahagow, Lanarkshire. 



Fti/. 3. Transverse section of Ca))ipophyllu)ii Miireluioni, E. & H., Lower 

 Carboniferous, Duruish, County Limerick. (In the collection of 

 the Geological Survey of Ireland.) 



Figs. 4, 4 A. Longitudinal and transverse sections of another example of 

 the same, Lower Carboniferous, near Beith, Ayrshire. In all 

 these examples the narrow outer vesicular zone is more or less 

 completely tilled up. 



Figs. 5, 5 A, 0, 6 A, 7, 7 a. Longitudinal and transverse sections of dilferent 

 examples of a coral possibly belonging to Calopliyllum, Dana. 

 The structure is nearly allied to that of CanipophiiUum ; but there 

 is an absence of any exterior zone of vesicular tissue. The spe- 

 cimens are from the Lower Carboniferous of Ayrshire.

Figs. \, 2, & 3, Transverse sections of a large species of CgathophyUum, 

 closely allied to C. gigantcum, Mich., but ditfering in the nature 

 of the dissepiments, the number of the septa, and certain other 

 particulars. The specimens exhibit a large septal fossula. Lower 

 Carboniferous, Ireland. (In the Collection of the Geological 

 Survey of Ireland.)

 parous development. Lower Carboniferous, Brocldey, near 

 Lesmahagow, Lanarkshire.

 passing inwards to near the centre of the visceral chamber.
