Kemakks. — The collection includes a fossil which is probably the 

 cast of a massive Sympliyllia, and agrees more closely in general 

 appearance with Symphyllia erytliracea than with any other species. 

 The specimen is not in a condition for positive determination. 

 Walther^ has figured a coral from the raised reefs of Jebel Hamman 

 Musa on the coast of the Gulf of Suez, opposite the locality whence 

 the Egyptian Survey specimen was obtained, which probably also 

 belongs to this species. 



Ponrtales- and Duncan^ have both urged that Isopliyllia and 

 Sympliyllia should be merged, a pi'oposal with which I agree : this 

 species is therefore included in Sympliyllia, as that name has three 

 years' priority.
