EOEAMINIEEEA FEOM THE NOETII ATLANTIC AND AECTIC OCEANS. 425 
The allusions to the Foraminifera in the Soundings “E. No. 37,” “ H. No. 2,” and 
“H. No. 67,” are not precise enough for the determination of the species found therein ; 
and even with the notes appended to the account of the Species, we cannot make a very 
exact table of the distribution. 
In Professor Bailey’s plate illustrating his memoir, we have 
1. Orbulina universa , D’Orb., tig. 1. 
2. Nodosaria , a fragment, tig. 8. With almost cylindrical chambers, as in some sub- 
varieties of N. Pyrula , D’Orb. Several fragments in the deeper soundings are said to 
have occurred. 
3. Dentalina mutabilis , Bailey, tig. 7. This fragment might well belong to such a 
subvariety of Dentalina communis as D. pauperata, D’Orb. Several fragments were 
found in “FI. No. 1.” 
4. Marginulina Racliei, Bailey, tigs. 2-6. Figs. 2-4 are the same as If. similis, D’Orb., 
and M. pedum, D’Orb., all of these being dimorphous or Marginuline modifications of 
Nodosaria Rctdicula, Linn., sp„ ; and figs. 5, 6 represent a larger individual of the same 
form, such as has been named Marginulina regularis by D’Orbigny in his ‘ Foram. Foss. 
Bassin Vienne,’ where the others are figured. 
5. Robulina D’Orbignii , Bailey, figs. 9, 10. This is the common Cristellaria cultrata, 
Montfort, sp. The figured specimen has its last few chambers keelless, and trying, as 
it were, to leave the discoidal plan of growth, each having its septal aperture almost free. 
This is said to accompany the foregoing, which was in considerable numbers in all 
except the shallow soundings. 
6. Rotalina Rhrenbergii , Bailey, figs. 11-13. This is Planorbulina Haidingerii , D’Orb., 
sp. (a variety of PL far eta, Fichtel and Moll, sp.), and occurred in “ F. No. 25.” and in 
several of the deeper soundings. Professor Bailey thought it to be near Rotalia Soldct- 
nii , D’Orb. ; and in truth Pl. Haidingerii does resemble that form, — but as an isomorph, 
not as a relative : so also it is an isomorph of Pulvinulina truncatulinoides, D’Orb. 
7. Rotalina cultratal , D’Orb., figs. 14-16. This is the common Pulvinulina Menar- 
dii , D’Orb., a variety of P. repanda , Fichtel and Moll, sp. Deferred to as common in 
the deeper soundings. 
8. Rotalina semipunctata , Bailey, figs. 17-19. The same as Planorbulina Ungeriana, 
D’Orb., sp. ( Pl.farcta , var.). 
9. Globigerina rubra , D’Orb., figs. 20-24. Professor Bailey rightly considered figs. 
20-22 to represent a separate form; it is Gl. inflata , D’Orb., a variety of Gl. bulloides , 
D’Orb., to which all must be referred specifically, D’Orbigny’s GL rubra being so named 
on account of the ruddiness of its shell, which is not dependent on the sarcode for its 
pink colour. GL inflata is specially noticed as occurring at 105 fathoms. Vast num- 
bers of Globigerina occurred in the deeper soundings, especially the deepest ; whilst they 
were but few and small at 49 fathoms. “ The abundance in which the species of Globi- 
gerina occur in the deep soundings G„ No. 31 and H. No. 1 gives to these green muds a 
most striking resemblance to the green Tertiary marls perforated by the artesian wells
