I.-INTRODUCT1ON. 



THE Cephalopoda taken liv the 'Terra, Nova" consist of about sixty-eight specimens 

 belonging tn seveuteeii species and twelve genera. More than half <>f the collection, 

 consisting of nine species ami some forty specimens, belong to the Octopoda, the 

 abundance of the genus Jfoschiti's being very striking. The Myopsida are represented 

 by one species only, and, while it is not surprising to rind that the X< /</'<> family is 

 entirely absent, it seems rather remarkable that so few small Oegopsids were taken. 

 Geographically, the waters explored by the "Terra Nova" in which Cephalopods 

 occurred may be separated into three divisions namely, the Atlantic from south of 

 Madeira tn off Monte Video; the Pacific, to the north of North Island. New Zealand ; 

 and. thirdly, various points within the Antarctic Circle. .loubin (191'2) has remarked 

 on our scanty knowledge of the Cephalopod fauna of this latter region, and, un- 

 fortunately, the present collection does not add any more species to the list, only two 

 species discnvered by the French Antarctic Expeditions being met with here namely, 

 Moschites charcoti (Jmibin). [taken at 80-207 fathoms on a varying bottom of mud, 

 glassv sponges, or undecomposed animal debris], and Moschites iur</niti (.loubin). 

 [taken ai _':.'_'- -:'>OU fathoms on mud]. A large damaged .]/--><///'/, x also occurred, and 

 possiblv the eyes of a large Oegopsid. particulars of which will be found in the text.

In the Pacific, olf North Island. New Zealand. M<>*<-/iif< > seemed to be entirely 

 absent, but only six hauls of the bottom fauna were made in this region, and
