Résumé. 
1. That the deep-sea corals differ from the reef-building forms in not possessing 
certain important ccenenchymal structures. 
2. That deep-sea corals have been dredged up from a depth of 1094 fathoms. 
3. That deep-sea corals live in very different temperatures, from 29°°9 to 56°3 
Fahrenheit. 
4, That the growth of deep-sea corals is very vigorous at great depths and in low 
temperatures. 
5. That the variability of deep-sea species is very great. 
6. That genera and species exist at great depths which are unknown elsewhere. 
7. That the horizontal distribution of many deep-sea forms is great. 
8, That the present deep-sea coral faunas contain species and varieties of species of 
3B2
