deep sea hardly supports Ortmann's theory, for many 

 of them occur at very great depths only in the temperate

The genus (after allowing for Haeckel's weeding out 



of synonyms) is curious in its distribution, in that the 



species H. macloviana is the only representative in 



southern seas, and even this has, as yet, only been 



recorded from the Falkland Islands. The other members 



of this genus are found in the temperate and cold regions 



of the northern hemisphere as well as in the north tropical 



zone.
