tion is sufficient to determine the matter, and until his type-speci- 

 mens are restudied, the genus can not be considered vaUd. The other 

 three species referred to Myriolithes by Eichwald are from 

 Carboniferous strata and undoubtedly belong to a genus 

 distinct from the Ordovician type.

Although this is registered as a Monticulipora by Eich- 

 wald, his figured specimen is undoubtedly a coral like Heliolites and
