A peculiar assortment of large continental rock fragments more or less 

 unprognated and covered with Manganese was brought up by the trawl at 

 Stat.on 2, lat 28^ 23' N., long. 126^ 57' W., 2368 fothoms, 450 mileJ fLm

A con,panson of this map with the n.ap published in the "Challenger" 

 Report on Deep-Sea Deposits in 1891 shows at a glance that a lar^e n.ass 

 of n.format.on bearing upon the distribution of n.arine deposits hL been 

 collected m the mterval. Frou. the numerous surveys made under the 

 ausjnces of the British Admiralty in the S. W. Pacific, and northeastward 

 to he Sandw.ch Islands and the American coast, in connection with the 

 Bnush cable between Australia and British Columbia, from the work of the 

 Albatross and other ships of the U. S. Navy and U. S. Fish Comnussion 

 and rom other sources, we have derived much information both regarding 

 the depth and the deposits of the Pacific. The chief modifications on the 

 deposit map of 1891 are,— 



(1) The increased area occupied by the Radiolarian Ooze, in lat. 3" to 

 12 N., extendmg from long. 165^ to 80° W., and also in lat. 8' S to 6° N 

 and long. 162° to 177" W. 



(2) The alterations in the form of the Globigerina Ooze areas, which 

 are now, m the vicinity of the Coral Islands, more circumscribed, while the

 Pacific Ocean, extending from off Yezo Island, Japan, hugging the Kurile 

 and Aleutian Islands, to off Vancouver Island, British Cohunbia The 

 existence of this Diatom Ooze band was recognized during the examhialion
