OF THE KERGUELEN REGION OF THE GREAT SOUTHERN OCEAN. 393 



distributional notes accompanying each species it will be observed that 15 of the 

 species are true deep-sea forms, being unknown from depths less than 1000 fathoms ; 

 the other 10 species, though found in depths greater than 1000 fathoms in the 

 regions represented by these twenty-nine Stations, occur outside those regions in depths 

 less than 1000 fathoms, and only one of these species (Oythere scutigera) appears to be 

 an inhabitant of shallow water under 150 fathoms. It will also be noticed that 15 of 

 the species occur in the tropical Pacific, 7 species in the tropical Atlantic, while 1 species 

 is common to both the tropical Pacific and tropical Atlantic, the remaining 2 species 

 beini:^ recorded from the Indian Ocean.

LIST 11./. 



In the second place w^e give a list of the 19 species which have been recorded 

 from reo-ions north of the northern tropic as well as south of the southern tropic, 

 but which, up to the present time, are not known to occur within the intervening 

 tropical zone. From the distributional notes accompanying each species it will be 

 observed that 12 of the species are true deep-sea forms, being unknown from depths less 

 than 1000 fathoms [in the case of Pyrosoma spiyiosum, though the trawl descended to 

 a depth of 2200 fathoms, it is pretty certain the specimen entered the net near the 

 surface]; the other 6 species, though found in depths greater than 1000 fathoms in the 

 reo-ions represented by these twenty-nine Stations, occur outside those regions in depths
