Fig. 21. Rotalia profunda, 10,998'.

According to the nomenclature of English rhizopodists (see 

 "Annals Mag. Nat. Hist.," ser. 4, vol. ix., p. 211, 280 ; x., p. 184, 

 253, 453, and for March 1, 1873), the study of Dr. Ehrenberg's 

 genera and species would lead us to regard figs. 1-5, 9-16, and 

 22 as various individuals of Globiyerina bulloides, D'Orb., with 

 some modifications of spirality and size of chambers, whilst 

 fig. 23 and figs. 24 and 25 of PI. II. are GlobigerincB within the 

 specific limits of Gl. bulloides, but varietal, near clevata and 

 helicina (D'Orb.). Fig. 6 is Lagena globosa, var. ; 7, Qui7i- 

 queloculina ; 8. Textularia sagittula. Figs. 17 and 19-21, are 

 PlcmorbulincB, small growths and varieties of PI. vulgaris pro- 

 bably ; and fig. 18, Nonionina. Looked at in this light, this 

 group of Foraminifera, excepting its far great richness in Globi- 

 gerince, is to a great extent such as has been described from 

 Davis' Strait and Baffin's Bay by Parker and Jones in the " Phil. 

 " Trans.," civ., 1865. See above, pp. 192, 193. 



Besides Davis' Strait, Hingston Bay, Greenland, has also 

 yielded Microzoa to Dr. Ehrenberg (" Monatsber.," 1853, p. 523, 

 &c.). All of the foregoing, together with the materials he ob- 

 tained from the First and Second* German North Polar Expedi- 

 tions ("Monatsb.," 1869, p. 253, &c., and 1872, p. 282, &c.) and 

 one sounding from Behring's Strait (** Abhandl.," 1872, p. 195), 

 Dr. Ehrenberg has grouped in the " Abhandl." for 1872 (Table, 

 pp. 220-329), with the following results for the <* North-Polar 

 Zone " :— 



Polythalamia (Foraminifera), 36. 



Polygastrica (Diatomacese, &c.), 92. 



Polycystina, 6. 



Phytolitharia (51), Geolithia (3), and Zoolitharia (4), (spicules 

 of Sponges, &c.), 51.

 Depths in Seas abounding in Floating Ice, in 

 Arctic Regions near Greenland and Spitzbergen.

" Dr. Torell, after he had examined, between the years 1856 

 and 1860, the glaciers of Switzerland, Norway, Iceland, Green- 

 land, and Spitzbergen, was appointed to command in 1861 a 

 scientific expedition fitted out at the joint expense of the Swedish 

 Government and Prince Oscar of Sweden. It consisted of two
