Kionoceras myrice Hall and Whitfield from the Cedarville of 
Ohio which is the Ohio equivalent of the Racine of Wisconsin. 
Actinoceras backi Stokes was identified by Foord from Bessels 
Bay, about 20 miles southwest of Offiey Island, and from Cape 
Louis Napoleon, 120 miles southwest of Bessells Bay and 35 
miles northeast of Bache Peninsula. Another Actinoceroid was 
found at Dobbin Bay, directly west of Cape Louis Napoleon. 
Trochoceras horeale Foord was described from Wellington 
Channel, between North Devon and Cornwallis Islands. It 
appears related to the Ordovician Eurystomites among the Tar- 
phyceratidae, Orthoceras griffithi Haughton, a vertically striated 
species, was described from Griffith’s Island, south of the middle 
of Cornwallis Island. Endoceras ommaneyi Salter was described 
from Assistance Bay, on the southern coast of Cornwallis Island. 
According to Haughton it was a cyrtoceraconic shell. 
Actinoceroids appear to be relatively common on Southampton 
Island, which blocks the northern end of Hudson Bay, and 
Actinoceroids are common also in the Silurian areas west of 
Hudson and James Bays. 
To me the affinities of these American Arctic cephalopods are 
with American forms, especially of Racine and Drummond Island 
type, and not with those of the Scandinavian-Baltic areas. 
However, such a minute part of the great Arctic regions has 
been investigated so far that it easily is possible for Silurian 
zones of European facies to turn up elsewhere in Arctic areas 
some time in the future. The vastness of these Arctic areas 
may be realized from the fact that Greenland is as long as the 
distance from Ottawa in Canada to Cuba; Baffin Land is as 
long as the distance from Cincinnati, Ohio to Portland, Maine. 
Ellesmereland is as long as the distance from Cincinnati to the 
Gulf of Mexico. At least half a dozen of the lesser islands equal 
in size at least two-thirds of that of the state of Ohio. Evidently 
there are innumerable possibilities of future discoveries. 
The present paper was inspired by Dr. Holtedahl’s extremely 
important communications on the geology of various Arctic 
areas, briefly reviewed on the preceding pages. While engaged 
on the study of Arctic Ordovician and Silurian cephalopods the
