 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-
