FORAMINIFERA FROM THE NORTH ATLANTIC AND ARCTIC OCEANS. 329 
this region. Cassidulina abounds, but is not large. A small Nummulina, the feeble 
representative of a once highly potent species, still abounding in some warm seas, is not 
wanting in the “Coralline-zone.” The essentially Arctic form of Bulimina (B. elegantis- 
sima ) flourishes at from 30 to 70 fathoms at the Hunde Islands, and other varieties are 
not wanting, though not abundant. The Textularice are represented by some small spe- 
cimens of the type, and by three of its modifications in small but numerous individuals. 
Spirillina is very rare and small. Patellina is small and common from 30 to 70 fathoms. 
Trochammina is common, though small, in the deepest sounding. Cornuspira is common 
at the least and the greatest depths. Quinqueloculina is common, but not large, 
throughout. Triloculina occurs freely at 25 to 30 fathoms. Lituola abounds from 25 
to 70 fathoms. 
3. From the coast of Norway, between North Cape and Drontheim, from 69° to 63° 
N. lat. Dredgings made by Messrs. MacAndrew and Barrett in the summer of 
1855. 
One portion of these materials* was received from the late Mr. Lucas Barrett, in 
small boxes, numbered, and labelled with the depths and localities of the dredgings ; 
another portion, received from Dr. Woodward, was the sandy refuse from a jar in which 
specimens of Mollusks, &c. had been preserved in spirits ; and, thirdly, Dr. Bowerbank 
favoured us with a packet of shelly sand obtained when preparing sponges taken in the 
same dredgings. The latter lots of sand were manipulated and examined together^, no 
particular depths and localities being noted for these mixed results of dredgings in from 
30 to 200 fathoms. 
The series of which the exact localities and depths are known comprises seven lots ; 
these with their characters and contents are arranged in the following Table (No. III.). 
The Bivalved Entomostraca from these dredgings have been determined by Mr. G. S. 
Brady, as follow : — 
Cythere Minna, Baird. Cythere catenata, Brady. 
spinosissima, Brady. Cytheridea Bradii, Norman. 
clathrata (varieties), Reuss. Cytherella Beyrichi, Reuss. 
* These Norwegian Foraminifera have already been noticed and illustrated by us in the Annals of Nat. Hist. 
2 ser. vol. xix. pp. 273, &c., pis. 10 & 11 (1857) ; we are, however, desirous of emending some of the 
descriptions there given, as well as the nomenclature and classification in several points ; and these Foraminifers 
are here brought into association with their allies of the neighbouring ocean. 
f The specimens from this mixed material are grouped together in pi. 10 of the Ann. Nat. Hist. 2 ser. vol. xix.
