70 Mr. C. O. Waterhouse on two 



transverse sections of the same, showing the structure at dif- 

 ferent stages of gTowth. 



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

 boniferous, Brockley, near Lesuiahagow, Lanarkshire. 



Fly. 3. Transverse section of Caynpophyllum 3Iurchisoni, E. & H., Lower 

 Carboniferous, Durnish, 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 hlled up. 



Figs. 5, 5 A, G, 6 a, 7, 7 a. Longitudinal and b-ansverse sections of different 

 examples of a coral possibly belonging to Calophyllum, Dana. 

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

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

 cimens are from the Lower Carboniferous of Ayrshire. 



Plate VII. 



Figs. 1, 2, & 3. Transverse sections of a large species of Cyathophyllum, 

 closely allied to C. giganteum, Mich., but differing in the nature 

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

 particulars. The specimens exhibit a large septal fossula. Lower 

 Carboniferous, Ireland. (In the Collection of the Geological 

 Survey of Ireland.) 



Figs. 4 & 5. Transverse sections of Cyathophyllum, sp., exhibiting fissi- 

 parous development. Lower Carboniferous, Brockley, near 

 Lesmahagow, Lanarkshire. 



Figs. Q, 6 a. Amplexus {Cijathopsis) comu-bovis, Mich., showing the septa 

 passing inwards to near the centre of the visceral chamber. 

 Lower Carboniferous, Ayrshire. 



Fig. 7. Cyathophyllum paracida, M'Coy, showing calicular gemmation ; 

 7 A, longitudinal section of the same ; 7 b-7 d, transverse sections 

 of the same. Lower Carboniferous, Lanarkshire. 



Fig. 8. Cyathophyllum, sp., transverse section. Carboniferous, Ireland. (In 

 the collection of the Geological Survey of Ireland.)

 the Families Buprestidse and Melolonthid^. By Charles 

 O. Waterhouse. 



Fam. Buprestidae. 



Stigmodera Saundersii, sp. n. 

 Oblonga, convexa, lata, nitida, viridi-cgerulea ; elytris eyaneis, ma- 

 culis quatuor cocciueis ; thorace convexo, longitudine ^ latiori, 

 fortiter crebre punctate ; scuteUo parvo, nitido ; elytris thorace 

 vix latioribus, at 2^ longioribus (apicibus rotundatis), punctato- 

 striatis. Long. 8 lin., lat. 3|- lin. 



This species is peculiar for its broad, very convex form, and
