FORAMINIFERA FBOM THE NORTH ATLANTIC AND ARCTIC OCEANS. 423 
observed that wherever Foraminifera are abundant small individuals are plentiful, but 
they very rarely represent other types than those to which the larger specimens are 
referable. 
Appendix II. — Professor J. W. Bailey’s Researches on the “ Virginian ” Foraminifera 
of the North Atlantic. 
“ Microscopical Examination of Soundings made by the U. S. Coast-survey off the 
Atlantic Coast of the U. S. By Professor J. W. Bailey,” Smithsonian Contributions 
to Knowledge, vol. ii. 1861, Article III. * 
The examination was made and reported in 1848. The soundings were taken off the 
coast of New Jersey and Delaware, from lat. 50° to lat. 38° N., varying in depth from 
10 to 105 fathoms. In the deeper soundings Professor Bailey found “ a truly wonderful 
development of minute organic forms, consisting chiefly of Polythalamia” (Foraminifera). 
He also remarked that these deep soundings were from a sea-hed under the influence, 
more or less, of the Gulf-stream ; and that probably this might cause an immense deve- 
lopment of organic life — giving rise to a “ milky way of Polythalamia.” Professor 
Bailey also noticed that Foraminifera abundant in deep water would necessarily there 
make extensive calcareous deposits, contrasting with the quartzose and felspathic sands 
and muds of the coast. 
We will, in the first place, give abridged notices of those soundings which were found 
to contain Foraminifera ; and afterwards we will offer some remarks on Prof. Bailey’s 
specific determinations, adapting them to the nomenclature used in this monograph, and 
so make them available for comparison with our “ Celtic” forms. 
E. No. 37. About South-east of Montauk Point ; lat. 40° 59' 55", long. 71° 48' 55" : 
19 fathoms. Coarse gravel, mingled with ash-coloured mud. With a few small Fora- 
minifera , chiefly Botalina ; a small bivalve Crustacean, Biatomacece, and Sponge-spicules. 
E. No. 9. Lat. 40° 21' 54", long. 70° 55' 35" : 51 fathoms. Greenish-grey mud or fine 
sand, with a few bits of shells, and a considerable number of Foraminifera , among which 
were Marginulina Bachei , Bailey (fig. 5, not abundant), Bobulina D'Orbignii, Bailey 
(figs. 9 & 10), and Bulimina auriculata, Bailey (figs. 25-27). 
F. No. 27. About South-east of Fire Island Inlet; lat 40° 14' 13", long. 72° 21' 30": 
20 fathoms [material not described]. One specimen of Quingueloculina occidentalism 
Bailey (figs. 46-48) ; with a spine of Echinus and small plates of an Echinoderm. 
F. No. 24. Lat. 39° 52' 40", long. 72° 14': 49 fathoms. Greenish grey, rather coarse 
sand, mixed with some mud. Foraminifera rather abundant, comprising Marginulina 
Bachei , Bailey (fig. 5, rather common), Orbulina universa, D’Orb. (fig. 1, rare), a small 
Bulimina, a few small specimens of Globigerina ; also a few Sponge-spicules, a small 
Cypridiform Crustacean shell, and a spine of Echinus.
