rhis table shows that Briaridse were secured at 25 of the Stations explored by the 

 Siboga Expedition. Of the twelve species secured, seven were new. By far the most coinmon 

 species was Solenocaulon sterroklonium which was found at eleven Stations, ranging in depth 

 from about 13 meters to 369 meters. The greatest depth at which a membei- of this family was 

 secured was 1165 t<> 1264 meters where Suberia macrocalyx was dredged. Other comparatively 

 deep-living species are Solenocaulon querciformis, from 828 meters: Paragorgia splendens, from 

 522 meters and Suberia köllikeri, from 520 meters. 



All of the species are confined, so far as known, to the Indo-Pacific region. The 

 distribution of the five species previously named being as follows: 



Solenocaulon sterroklonium, Ternate, Indian Ocean. 



Solenocaulon grayi, Northwest coast of Australia and Indian < >cean. 



Semperina rubra, Bohol, Philippine Islands.
