1. Sahul Bank; ii° 30' S. lat., 125 E. long. — Three specimens; 

 one of these has the arms 105 mm. long and the cirri 87 mm. long ; 

 another is similar ; the third is very small with arms only 35 mm. 

 long, but it has already developed the compressed and overlapping

 two brachials, which are practically confluent on succeeding ossicles ; 

 the axillaries bear a single sharp keel.
