DISCORBINA PAIUSIENSIS, ttOrbigny. Discovery Passage at station No. 7, and Queen 

 Charlotte Sound at stations Nos. 14 and 17, not uncommon. Double specimens, in 

 which the bases of two shells have grown together, or specimens which have been 

 double, but which have been broken apart by some cause unknown, are more 

 frequent than normal and single examples. In the ninth volume of the Zoology 

 of the "Challenger" Expedition (p. 649) Mr. Brady says "it is probable that the 

 phenomenon is to be accounted for in the same way in all cases, that it is brought 

 about by the extension of a lobe of sarcode from the mouth of the parent test, the 

 subsequent division of the nucleus, and the continued growth of the new 

 individual withoiat separation from the parent, a very similar process to that 

 minutely watched by Gruber in a species of Euglypha. "
