Expedition, namely lat. 83° 19' N. This, considering the few 

 opportunities for sounding, and the difficulties under which 

 material was obtained, may be regarded as very satisfactory — 

 the more so because whatever facts are derived from specimens 

 procured between the latitudes named are distinct accessions 

 to our knowledge, no previous observations of the same sort 

 having extended even to the southern limit. It is not 

 proposed in this place to do more than give a list of species, 

 and to make a few remarks on the general aspect of the 

 fauna ; technical details are better suited for publication 

 elsewhere. 



Our knowledge of Arctic Rhizopoda is chiefly derived 

 from the researches of Professors W. K. Parker and T. 

 Rupert Jones, and of the Rev. A. M. Norman. The memoir 

 of Messrs. Parker and Jones in the ' Philosophical Trans- 

 actions ' for 1865 forms the text-book of the subject. It 

 comprises the results of the examination of the soundings 

 taken by Sir E. Parry in Baffin's Bay, between latitudes 74° 45', 

 and 76° 30' N., of 'those by Dr. Sutherland off the Hunde 

 Islands, Davis Straits, in lat. 68° 50' N., and of dredgings 

 made by Mr. Mac Andrew off the coast of Norway between 

 lat. 65° and 71° N. Mr. Norman's investigations are founded 

 upon the dredgings brought home by Dr. J. Grwyn Jeffreys 

 from the cruise of the ' Valorous,' and a summary of them 

 forms one section of the Report published in the ' Proceedings 

 of the Royal Society' for 1876. In the same Report Dr. 

 Carpenter also adds a few general observations on some of the 

 larger forms of Foraminifera. Six of the dredgings brought 

 home in the ' Valorous ' were from within the Arctic Circle, 

 the most northerly being about lat. 70° N. 



Thus it will be seen that the area embraced by the 

 soundings which form the subject of the present notice 

 stretches nearly seven degrees further north than any hitherto 

 examined — in point of fact, it covers about half the distance 

 between the highest latitude of Sir E. Parry's series and the 

 actual North Pole. The following is the list of the For- 

 aminifera which have been obtained : —
