less than 1000 fathoms, and only one of these species (Pseudocy there caudata) appears 

 to be an inhabitant of shallow water under 150 fathoms. It will also be noticed that 16 

 of the species are represented in the North Atlantic and 4 species in the North Pacific, 

 while only one of these 19 species (Dentalium heras) is common to both the North 

 Atlantic and North Pacific.

LIST lie. 



In the third place we give a list of the 24 widely-distributed species which are 

 known to occur both in the tropical and northern extra-tropical regions as well as 

 south of the tropics. From the distributional notes accompanying each species, it 

 will be observed that only 4 of the species are true deep-sea forms, being known only 

 from depths greater than 1000 fathoms ; the other 20 species, though found in depths 

 over 1000 fathoms in the regions represented by these twenty-nine Stations, occur 

 outside those regions in depths less than 1000 fathoms, and 8 of these species appear 

 to be inhabitants of shallow water under 150 fathoms. Three of the species (viz., 

 Gennadas parvus, Parapagurus abyssorum, and Discina atlantica) appear to be almost 

 cosmopolitan.
