454 NOTES ON DR. AMI'S PAPER ON DICTYONEMA SLATES. POOLE. 



from the syncline at Green Bank, Point Pleasant Park, Halifax. 

 I obtained it last autumn, but could not detect other structures 

 in the same beds * 



D. Websteri was named by Hall forty years ago; if it be the 

 same as D. fldbelliforme or D. sociale, I for one am not disposed 

 to take later names " made in Germany," but contend we should 

 maintain our oldest Nova Scotian name of D. Websteri. 



A consideration of dates shows that the Eel River fossils 

 were reported on a year before Dr. Ami wrote his Synopsis, and 

 it is hard to understand how their discovery influenced Dr. Ami 

 AFTER he wrote his Synopsis. 



Nor can we cannot accept Dr. Ami's conclusion, that the 

 specimens of D. Websteri at McGill are the type specimens. 

 Hall named it, and Dr. Webster's collection of some two dozen 

 slabs are in the Provincial Museum at Halifax. They show 

 cellules, etc., and, I fancy, a second species. 



Any examination in criticism of the finding of Hall should 

 "be made of the large collection in the Halifax Museum, and at 

 Wolfville, and not be restricted to the two specimens at McGill. 



* The specimen i9 now in the Provincial Museum at Halifax.
