The table shows that species of this family were secured at i8 stations, and that one 

 species was secured at each station, with the exception of Station 273 where two species were 

 found. This station must have been exceedingly rich in alcyonarian life, although but two of 

 the Sclerogorgidae were secured here. 



This family seems to be largely confined to shallow water, as but a single species was 

 secured from a depth greater than 100 meters. The species referred to was Suderogorgia 

 kollikeri, secured at Station 305 at a depth of 1 1 3 meters. 



Two of the species in the Siboga collection, however, were secured by the Challenger 

 off Japan at a depth of 345 fathoms. These are Suderogorgia verricnlata and 5. kollikeri. 



If Thomson and Simpson ^ are correct in regarding Korandes gracilis and K. pallida as 

 synonyms of K. korejii, this .species has a wider range than any other of the family Sclero- 

 gorgids in the collection, extending from the Indian Ocean to Japan and the Hawaiian Islands.
