quartz, mica, glauconite, and red and black minerals ; many pelagic 

 and other Eoraminifera, Coccoliths, and Ehabdoliths ; a few siliceous 

 spines. 

 Beautiful and wonderfully perfect casts of the carbonate-of-liine organ- 

 isms remained after treatment with acid, as Echini-seines, Polyzoa, and 

 Eoraminifera, &c. Some of these were dark green, some pale green, and 

 others a dirty white colour. 



Compare 600 fathoms, off Orozets. 

 Soundings 197 and 198. Lines parted. 



Sounding 199. 17th June, 1874. 2600 fathoms. Lat. 34° 50' S., long. 

 155° 28' E. A red clay containing : — Amorphous clayey matter ; 

 many exceedingly fine mineral particles, quartz, mica, red and green 

 particles (pumice?) ; a good many broken pieces of pelagic Eorami- 

 nifera and a few Coccoliths ; one or two pieces of siliceous spines ; 

 one or two manganese grains. 

 Sounding 200. 19th June, 1874. 2600 fathoms. Lat. 36° 41' S., long. 

 158° 29' E. A red clay containing : — Amorphous clayey matter ; 

 many very fine mineral particles of a white and black colour ; a few 

 broken pieces of pelagic Eoraminifera ; a few broken parts of 

 Eadiolaria; a few manganese grains. 



Sounding 201. 21st June, 1874. 1975 fathoms. Lat. 37° 53' S., long. 

 163° 18' E. A white Globigerina-ooze containing: — Very many 

 pelagic Eoraminifera, Coccoliths, and Ehabdoliths ; much amorphous 

 calcareous and some clayey matter ; a good many Eadiolaria ; one 

 or two black and small white mineral particles (scoria and pumice?). 



Sounding 202. 22nd June, 1874. 1100 fathoms. Lat. 38° 36' S., 

 long. 166° 39' E. A Globigerina-ooze containing : — Very many 

 pelagic Eoraminifera, Coccoliths, and Ehabdoliths; some amorphous 

 calcareous matter ; a good many Eadiolarians and some Diatom 

 remains ; one or two small green and red mineral particles. 

 There were one or two nearly pure white casts of Eoraminifera. 



Sounding 203. 23rd June, 1874. 275 fathoms. Lat. 38° 50' S., long. 



169° 20' E. A small quantity which came up indicated Globigerina- 



ooze, containing : — Many pelagic and other Eoraminifera ; many 



Coccoliths, Ehabdoliths, and Echini-spines. 



The trawl brought up many Grlobigerinas, Pulvinulinas, Orbulinas, and 



other Eoraminifera, Echini-spines, surface-shells, &c. All the finer 



portions of the bottom had been washed out of the bag. 



23rd June, 1874. 400 fathoms. A Globigerina-ooze containing: — 

 Many pelagic Eoraminifera, Coccoliths, and Ehabdoliths (the Cocco- 

 liths were very large and numerous, and made up perhaps 15 cwt. 

 of the bottom); one or two Eadiolarians and a few remains of 

 Diatoms ; a few white and small green mineral particles.
