Following the activities of the Blake, explorations were made by 

 steamers of the United States Fish Commission in the deeper waters 

 off the Xew England coast and off the Delaware Capes, extending 

 their field of operations to the Hatteras region, from inshore stations 

 to the abyssal depths beyond the continental slope. These were the 

 Fish Hawk in 1880-18S2, and the Albatross in 1883-4. The mol- 

 lusks so obtained were made subjects of a series of papers by A. E. 

 Verrill, published in the Transactions of the Connecticut Academy of 

 Aria and Sciences in 1882, 1883, and 1885, and also by Katherine
