Frempen, R.A., F.G.S., and Roserr Erseriper, , ERS, 
F.G.S.—In this communication the authors bro sora hens the 
Society the paleontological results and details of the collection 
made by the naturalists and other officers of the late expedition 
to the rah Circle — Admiral Sir G. Nares. The purpose 
of the paper was to record the presence of inte ~ Carbonif- 
erous fossils i in the highest latitude yet reache 5’ N. 
the former group 60 species have been Seb oi eis ay from 
Silurian species of Actinozoa belonging to Halysites, Havosites, 
Heliolites, wees Laphrentis, Amplexus, Cyathophyllum, and 
Arachno ophyl lum were noticed, and correlated with British forms 
when possible; but, on the whole , the facies of io aint a 
genera were noticed—Bronteus, Calymene, Enerinurus, and 
Proétus, all Upper Silurian ; and the genus Asaphus, associated 
with Maelurea, of Lower Silurian age. Ten species of thio 
da belonging to the genera Pentamerus, _Rhynchonella, Chonetes, 
Atrypa, Strophomena have been determined. 
Collections were made from twenty isaelibics, seeing é from lat. 
79° 34’ to 82° 40’ N., notably the highest at Cape Joseph Henry, 
where Captain Feilden obtained a numerous arboniferous-lime- 
si fauna, numbering about thirty species, chiefly eapirnhice sn

allied to that of America than to that of Europe, and thus must 
be correlated with it, although it was shown that a large number 
of species are common to the two areas, especially the British 
Islands. The absence of Lamellibranchiata in rocks older than 
the Tertiary was noticed as having special psa in the physio
