westward, however, along the wide abyssal depths (to about 45° 30' W. long.), even at 
more than 2000 fathoms, we find a larger fauna, of but few species, among which 
Orbulina and Globigerina are characteristically abundant (especially the latter), and are 
accompanied by Lagena (rare), Discorbina, Uvigerina, Rotalia Soldanii, Pulvinulina 
Menardii, P. Micheliniana , and P. Canariensis, occasional specimens of Pullenia, a few 
Nonionince and Polystomellce (P. striatopwnctata) , a few Rulimince, very few Textwlarice , 
and scattered small Milioloe and Lituolce . In the western portion of this territory the 
fauna is somewhat poorer, where naturalists have drawn the southern portion of their 
“ Boreal Province.” 
Rising the western slope from the abyss (40° 45' to 49° 23' W. long., parallel to the 
northern end of the Bank of Newfoundland), we enter the great southern angle of the 
“Arctic Province,” and the Foraminiferal fauna continues to have much the same 
elements ; but Globigerina and Orbulina have become rarer ; Miliolce are very rare ; 
Planorbulina comes in, Pulvinulince disappearing after the first upslant of the bottom at 
45° 45' W. long. 
From 50° 14' 30" to 52° 44' W. long., we are still off the northern edge of the 
Newfoundland Bank ; and, though the depth decreases from 405 fathoms to 161 and 
then to 112 fathoms, Foraminifera are extremely rare, owing, without doubt, chiefly to 
the coldness of ice-laden water. Truncatulina, Pulvinulina, Polystomella, and Uvigerina 
seem to struggle for existence here, where “Arctic” conditions are extended southwards. 
At 52° 56' and thence to 53° 57' 35" W. long, the line of soundings is in Trinity Bay, 
with depths varying from 124 to 195 fathoms. Only very scarce Globigerince, a few 
Pulvinulince, some Nonionince, rather more of the very persistent Cassidulince, and a very 
few Uvigerince, Rulimince, and Lituolce appear to inhabit this unfavourable locality at 
the depths examined. In fact this region belongs to the “ Arctic Province,” which is 
here prolonged southwards towards the Bank of Newfoundland by the influence of cold 
currents and icebergs. 
With the exception of the westerly soundings, these deep-sea gatherings from the 
North Atlantic illustrate the Foraminifera of the “Celtic Province”; but necessarily 
lack, as a fauna, the complementary shallow-water forms, — namely, those living in the 
Coralline, Laminarian, and Littoral Zones, at depths less than 40 fathoms. 
The materials from Davis Straits (Hunde Islands) above-mentioned serve to illustrate 
only for the “ Arctic Province” the Foraminiferal inhabitants of the Coralline-Zone ; 
and therefore do not fulfil the requirements of this case. We may take, however, as a 
term of comparison the list of the Recent Foraminifera of the British Isles, described by 
Professor Williamson, but classified (and partly renamed) after the plan here adopted, 
and augmented by later researches (including those by Mr. H. B. Beady, F.L.S.); and 
we thus have before us, in these combined lists, a synopsis of the Foraminiferal fauna of 
the “ Celtic Province.” (See Table IX. in Appendix V.) 
The deep-sea Foraminiferal fauna of the North Atlantic differs from the fauna of the 
Coralline, Laminarian, and Littoral Zones of the “Celtic Province” chiefly in having 
fewer varieties and (generally) smaller individuals of Nodosarina, Lagena, Polystomella
