which is covered by a yellowish soft limestone bed containing many fossil 
corals and echinoderms. Ha sayss 
"The fossils of the marls and limestones of Anguilla are generally 
badly preserved, most of them being only casts, which makes their de- 
termination very difficult." 
The collection of fossil corals made by Prof. Cleve was kindly lent 
me by the University of Upsala. The matrix of the specimens is a yellow 
calcareous clay and from Prof. Clave*® description I suppose that they 
were obtained from the soft yellowish limestone bed which immediately 
overlies the amygdalo idal igneous rock.
