of eaeh half at the middle is 10 mm. The dimensions of the 

 lateral parts are 42 by 13 mm. The rectum with its appen- 

 dages extends to the middle of the funnel. The appendages 

 are triangulär in shape, their point of fixation being at one 

 of the angles, and the two others ending each in a little tip, 

 the ventral of whicli is larger. The gills are long (100 mm.) 

 and fixed to the mantle up to their ends. The ink-sac which 

 is rather large is situated in the middle, with its posterior 

 end about 1 cm. anterior to the level of the base of the gills. 

 The stomach which has thin semi-transparent walls is situated 

 with its main mass behind the right gill. It is filled up 

 with bones and fragments of fish. The liver is very large 

 and oily, its capsule is thick and its bulk seems to be more 

 than all other organs taken together. The testicle is situated 

 to the left of the stomach and extends to the posterior end 

 of the pallial cavity. The organ which attracts most attention 

 when the pallial cavity is opened is the spermatophor-sac 

 and its efferent duct. It puts in appearance Coming out at 

 the base of the left gill; from there it makes a curvature 

 over to the right side but is however long enough to reach 

 out through the anterior (exterior) opening of the funnel. At 

 the act of copulation it thus certainly can be extended a 

 great deal outside the funnel and have the function of an 

 organ for copulation so that it may perhaps even be intro- 

 mitted in the pallial cavity of the female. This is the reason 

 why this form does not need any hectocotylised arms. It 

 was filled up by spermatophors of large size measuring from 

 40 to 45 mm. without the appendages which usually are two, 

 15 — 20 mm. in length, but varying a good deal. 



I have not taken out the gladius, only opened the posterior 

 end to see the shape and size of the »cone». It measured 42 

 mm. in length and was triangulär in section. It was also 

 solid all the way through, not hollow in any portion.
