The first section across tlie Atlantic, from Teneriife to Som- 

 brero, was tlirongli deep water, and principally over a bot- 

 tom of red clay, the most unproductive of all the deep-sea 

 sediments. The following table gives an idea of the pro- 

 portion in which the principal zoological groups were repre- 

 sented : 



The only stations in this section which can be considered at 

 all productive are No. III. and No. XIII., both on globigerina 

 ooze, and Station XXIII. in shallow water off the Island of 

 St. Thomas. At the other stations animal forms were few in 

 number, and apparently stunted in growth. 



In the next series of stations, from Bermudas to Sandy Hook 

 and Halifax and back to Bermudas, the conditions varied great- 

 ly ; but by far the greatest abundance of animal life occurred 

 in the comparatively shallow water, including one or two of 

 the cod banks off the American coast and the coast of Nova 

 Scotia. Tlie fauna of that region was of course, on the whole, 

 well known ; some interesting observations were, however, 

 made on the distribution of the subarctic fauna in deeper
