138 Mr. H. J. Carter on the 



Group 8. Foliata. 



Sarcode ? (absent.) Skeleton composed of a dense reticu- 

 lation of short-jointed, small, horny, anastomosing translucent 

 fibre of a brown or yellowish tawny colour, cored more or less 

 with minute foreign objects. Fibre of two kinds — viz. vertical 

 or large, and horizontal or small ; the former terminating at 

 the surface in small cored aculeations which are closely approxi- 

 mated. Structure vertical, radiating or plumose. Texture firm, 

 dense, tough, fine. Forms digitate ; digitations laterally united 

 and flattened, proliferous, foliate. 



Group 9. Dactylifera. 

 Sarcode ? (absent.) Skeleton, fibre, structure, and tex- 

 ture the same as the foregoing. Forms digitate ; digitations 

 simple or branched. 



Group 10. Fenestrata. 



Sarcode ? (absent.) Skeleton, fibre, structure, and texture 

 the same as the foregoing. Forms hollow and clathrous, or 

 massive lobed, or branched and fenestrate. 



Group 11. Platyfibra. 



Sarcode ? (absent.) Skeleton composed of a reticulation of 

 flaccid, flattened, horny, anastomosing translucent fibre, of a 

 light or brown colour, cored more or less with minute foreign 

 objects. Fibre of two kinds — viz. vertical or large, and hori- 

 zontal or small ; the latter arranged ladder-like between the 

 former, flattened and expanded, so as to present a clathrous 

 structure formed of circular holes of different sizes. Surface ? 

 (too much worn away for description.) Structure vertical, 

 radiating. Texture loose, flaccid, shreddy. Forms massive 

 lobed or branched simply, or simply flattened. 



Group 12. Peraxiata. 



Sarcode ? (absent.) Skeleton composed of a reticulation of 

 horny, anastomosing opaque fibre of a light grey colour, cored 

 throughout with minute foreign objects. Fibre of two kinds — 

 viz. vertical or large, and horizontal or small. Surface ? (too 

 much worn away for description.) Structure vertical, radiating, 

 plumose. Texture firm, rather compact. Forms branched, 

 lobed, and flattened.
