Ohs . — It is difficult to assign characters to a sjiecies whose fellows all 
resemhle one another as closely as do those of Ser'pula ; hut as this is the first 
yet noted from the Permo-Carhoniferous Series of New South Wales, I

"Waterhouse, M.A., were forwarded to Prof. T. Bupert Jones, F.B.S., who, 
after a careful examination with Mr. J. "W. Kirkhy, pronounced them a
