NEW SPECIES OF CAMBRIAN FOSSILS FROM CAPE BRELON. 
285 
From Parabolinalla Plantii , Salter, as figured by F. R. C. Reed, 
it differs in its arched front margin, broader glabella, differing glabellar 
furrows, and in possessing pygidial spines.* 
If it were not for the pair of marginal spines at the front corner of 
the pygidium, this species, from the flattened side lobes of the 
pygidium and other features, would fall under Brogger’s sub-genus 
Parabolinella.f 
The following scheme of the succession of faunas of the St. John 
group in New Brunswick, Canada (amended to include later dis- 
coveries), is quoted from Yol. VIII., Sec iv., p. 129 of the Transactions 
of the Royal Society of Canada, to show the relation of these Cape 
Breton species to the Cambrian succession as a whole.
