 distinct areolated cells, separated by raised ridges at the bottom of channels. Fig. 2d, small 

 portion, magnified, showing three ovicells, one of which is studded with avicularia ; numerous 

 sessile avicularia, mostly on calcareous bases, are seen on the cells with which the ovicells are 

 connected. Fig. 2e, fractured edge of polyzoary, to show the cells distinct throughout the 

 whole thickness ; the fracture was obliquely across the cells. 



I am indebted to my friend Mr. MacGillivray for the specimens
