I consider these specimens identical with the Cirro- 

 teuthis umbellata described by P. Fischer. As some of 

 the specimens are considerable larger than the ones 

 previously described some measurements may be recorded:

1st arm 300 mm 130 mm 72 mm 



2nd „ 260 „ 



3rd „ 230 „ 104 „

Length of fins 52 „ 38 „ 28 „ 



Length of mantle to centre of eye 83 



Diameter of eye 20 ,, 12 ,, 



We note the fact that all the specimens were taken 

 in the trawl. The coarse structure of the animal, and its 

 likeness to Opistoteuthis, seem to indicate that we 

 have to do with representatives of the genus Cirro- 

 teuthis which live near the bottom and form a transi- 

 tion to the typical bottom form Opistoteuthis. They 

 are so like the genus Opistoteuthis that the somewhat 

 damaged specimens at first sight might easily be 

 mistaken for the latter.

Two larvae, which 1 regret to say have been 

 badly damaged. Their likeness to the genus Vam- 

 pyroteuthis which I intend to describe more fully 

 later, is so obvious, that I refer them to this genus.

Stat. 82. 3000 m. w. The present memoir 

 ends with the description of a new and wonderful 

 type of Cirroteuthidae, which may probably be 

 counted among the most valuable spoils of the 

 expedition. The specimen is a perfectly gelatinous 

 semi-transparent cephalopod, the fragility of which 

 recalls that of a ctenophore. Notwithstanding this, 

 the specimen had been so well preserved in formalin, 

 that I am able to give a suitable representation of it. 

 Although the web on account of its excessive frail- 

 ness has been torn, I consider it desirable to reproduce 

 a photograph of the preserved specimen (fig. 7), 

 because it conveys a good idea of this peculiar 

 organism. The photograph shows that the posterior 

 end of the body runs into a flap, the mantle having 

 comparatively large fins. The eyes appear to be
