Two specimens of this species were taken by the U. 8S. Fish Commission, off 
Cape Cod, in 142 fathoms, Station 36, 1873. It has been taken in numerous 
localities off Florida and among the West India Islands, in 73 to 878 fath- 
oms, by the Bache and the Blake. It was also taken by the Porcupine 
Expedition, off the coast of Europe; by the Josephine Expedition, off Villa 
Franca, Azores, and on Josephine Bank, in 110 to 600 fathoms; by the Chal- 
lenger Expedition, off the Azores and Bermuda, in 1000 to 1075 fathoms, 
off Pernambuco, Brazil, in 675 fathoms, and’ in the South Pacific, in 2375 
fathoms. 
This is an exceedingly variable species. The living forms have been iden- 
tified by Duncan, and by Pourtalés, in his last paper, with the fossil species, 
Deltocyathus Italicus, from the Italian tertiaries.
