FORAMINIFERA FROM THE NORTH ATLANTIC AND ARCTIC OCEANS.

The Telegraph-line, in passing the northern end of the Bank of Newfoundland, 
enters (at about 47° W. long.) the Southern extension of the “Arctic Province”*, 
where the prevalence of floating ice keeps “ Arctic ” conditions as far south as 45° 
N. lat. This western extremity of the line does not belong, therefore, to the 
“Celtic,” but to the “Arctic Province”; and the few Foraminifera occurring there 
may be regarded as equivalent to those mentioned above as being found at similar 
depths in Bafiin’s Bay. 
The south-western extremity of the “ Boreal Province,” bordering the “ Arctic,” also 
invades the western part of the line of soundings f ; and is coincident with a somewhat 
impoverished condition of the abyssal fauna common to these soundings (Nos. 21-26) 
and others (Nos. 27-32) to the East (“ Celtic”). 
The accompanying Map (after Commander Dayman’s Chart), Plate XII., illustrates the 
foregoing remarks. See Appendix VII. 
We are fortunately able to compare the deep-sea Foraminifera of the North Atlantic 
with those inhabiting the shallower water of its western margin at a lower latitude than 
Newfoundland, where the Telegraph-soundings terminate. The late Professor Bailey’s 
examination^ of some soundings made by the United States Coast-survey on the shores 
of New Jersey and Delaware, between lat. 50° and lat. 38° N., in 1848, affords us the 
means of doing this, at least to some extent. 
Where the “ Celtic Province,” crossing the Atlantic from the British Isles, approaches 
North America, it takes on a modified character, and is known as the “ Virginian Pro- 
vince”; and its north and south limits are just those of the series of soundings made by 
the United States Coast-survey referred to above, and thus yielding us (as far as Professor 
Bailey’s figures and descriptions serve) the western equivalents of the eastern margin of 
the “ Celtic Province.” See Appendix II., and Table VIII. 
As far as Professor Bailey’s material shows, we find the “ Virginian ” fauna to be 
related to the “ Celtic ” of the Irish coast by Orbulina universa , Cristellaria cultratcc , 
Planorbulina TJngeriana (abundant in the Irish and rare in these American soundings; 
whilst its congener, PL Haidingerii, abounds here and is wanting in the soundings off 
Ireland), Pulvinulina Menardii, Globigerina bulloides , and Quinqueloculina Seminulum. 
All the recorded “Virginian” forms occur in the British seas, except Marginulina regu- 
larise Verneuilina triquetra, Bulimina Pyrula (represented to the eastward by B. margi- 
nata) and Virgulina squamosa.
