225-252 fathoms, 1880. Some of those specimens must liavo boon at least 

 20 nun. in diameter. They agree in all respects with the larger specimens 

 figured by Moseley. 



. This coral is remarkable fur having a wider range, in depth and geographi- 

 cally, than any other known species. It was first taken by Pourtales, olf 

 Florida, in 350 and 450 fathoms, on the Bache ; and in 100 fathoms, oft' 

 Barbados, on the Hassler. By the Challenger it was taken in the North 

 Atlantic, oft' the Azores and olf Bermuda, in 32 to 1075 fathoms; in the South 

 Atlantic, in 1900 to 2650 fathoms; in the South Indian Ocean, in 1600 to 1950 

 fathoms; in the Malay Archipelago and West Pacific, in 360 to 2440 fathoms; 

 cast of Japan, in 2300 to 2900 fathoms ; oft' Valparaiso, in 1375 fathoms. 

 Studer also records it from the Pacific Ocean. 



The Fanijiacyathus frafjilis of Sars closely resembles this coral, but according 

 to the figures its septa are not united into groups, nor are there any transverse 

 lissepiiueuts uor trabiculai in the four specimens described, although sunie of 

 tlieni were larger than many of the specimens of BatJiyadis, in which these 

 characters are well m;nkod. A larger aeries of the arctic furm may, however, 

 serve to unite them hereafter.
