DEEP-SEA CORALS. 



The deep-sea corals collected during the voyage of the United States 

 steamer Hassler from Boston to San Francisco are not as numerous as were 

 expected, variovis causes having combined in rendering deep-sea dredging 

 rather unsuccessful. The only rich locality discovered was off the island of 

 Barbados, a few miles north of Bridgetown, in depths varying from 80 to 120 

 fathoms. A few corals of interest were also obtained off the coast of Brazil 

 and off the island of Juan Fernandez. 



The opportunity is taken in this paper to make some remarks on the deep- 

 sea corals dredged by the late Dr. W. Stimjjson, during the last months of his 

 life, in the waters of Florida, Cuba, and Yucatan, in the United States Coast 

 Survey steamers Bibb and Bache.

 About one hundred and twenty specimens of this species were dredged at 

 Barbados in 100 fathoms. There is less variety of form in this than in any 

 other species examined, and the development of the fifth cycle in two half- 

 systems at one end of the longitudinal axis manifests itself at an early 

 age. There are, therefore, always fourteen pali, whilst C. formosa has never 

 more than twelve. The fourth cycle is never incomplete as stated by M.- 

 Edwards and Haime. The specimen described as C. herteriana in the Illus- 

 trated Catalogue of the Museum of Comparative Zoology, No. IV., from the 

 coast of Florida, I have now convinced myself is only a variety of C. formosa
