Br. J. W. Gregory/ — Egyptian Corals. 251 



Distribution. — Tnronian : Bausset, France (De Froraentel) ; 

 Abu Roasch, Egypt (Brit. Mus. Coll., E. 336, and Coll. Geol. Surv. 

 Egypt, No. 53). 



Figures. — PI. IX, Fig. la, corallnm from above, f nat. size; 

 Fig. 16, part of upper surface of corallum, x 2 diam. ; Fig. \c, some 

 oorallites seen in horizontal section, x 3 diam. Fig. 2, part of hori- 

 zontal section across another specimen, x 2 diam. 



Remarks. — The specimen used as the type of this variety was 

 presented to the British Museum by W. M. Newton, Esq. It is 

 well preserved, and shows the upper surface of the corallum. 

 A weathered specimen sent by the Egyptian Geological Survey 

 proves to be the same species ; the external surface has been 

 destroyed, and only transverse sections show sufficient of the septa 

 for determination.
