ME. W. K. PAEKEE AND PEOEESSOE T. E. JONES ON SOME 
culine Miliola , named Quinqueloculina tenuis by Czjzek in his description of some fossil 
Foraminifera from the Vienna Basin, in Haidinger’s Abhandl. Wiss. vol. ii. p. 149, 
pi. 13. figs. 31-34. 
This tiny shell, which presents an extreme enfeeblement of Q. Seminulum, Spirolocu- 
line in aspect and twisted on itself, occurs at great depths in the Mediterranean and 
other seas. We find it fossil in the Lias clay of Stockton, Warwickshire. 
In the North Atlantic Q. tenuis is small ; rather common at 415 fathoms on the mar- 
ginal plateau off Ireland ; rare at 2050 fathoms in the abyss. 
Description of the Plates. 
PLATE XII. 
Map of the Deep-sea Soundings, in the North Atlantic, from Ireland to Newfound- 
land, by Lieut. -Commander J. Dayman, R.N., assisted by Mr. J. Scott, Master R.N., 
H.M.S. Cyclops, 1857. With a Section of the Bed of the Atlantic Ocean from Valentia 
to Trinity Bay. The soundings are given in fathoms. Vertical scale 2000 fathoms to 
1 inch. Scales as 15 to 1. See Appendix VII. 
This Map is copied from Commander Dayman’s Report on the Soundings (1858); 
indications of the Natural-History Provinces, and of the thirty-nine Soundings described 
in this memoir, being added. 
Note. — In the ‘ Nautical Magazine,’ vol. xxxi. No. 11, November 1862, was published 
“ The Report on the Deep-sea Soundings to the Westward of Ireland, made in H.M.S. 
Porcupine, in June, July, and August 1862,” by R. Hoskyn, Esq., R.N., with a Chart, 
showing the slope of the Eastern Plateau to be, in that line of soundings, at a less angle 
off Southern Ireland than Commander Dayman found it where he sounded.
