NOTE) ON THE PRECEDING PAPER. 



Mr. Matthew's interesting remarks, courteously enclosed in 

 a letter to myself, will be welcome to workers in early 

 Palaeozoic strata on this side of the Atlantic. The important 

 point seems to be that the uppermost series of impressions of 

 the tentacles of Monocraterion runs over the more open part of 

 the true burrow, and that other sets of impressions are found 

 connected with the same burrow, a well-marked one occurring 

 as much as an inch below the uppermost. This seems 

 effectually to negative the idea that the various upper series 

 are inorganic repetitions of the lower, through subsidence of 

 several layers into the hollows left by the decay of the original 

 tentacles. At the same time, if all the impressions are 

 depressed on the upper surfaces of the layers, the tentacles 

 were probably retractile, and left grooves as they withdrew. 

 Mr. Matthew cannot intend us to conclude that the depressions 

 were caused by the decay of the tentacles after each protrusion.
