that the shortness of the mantle was due to its having been folded, a fact 

 which had not been observed owing to the transparency of the animal, and 

 that the difference in the fin is owing to mutilation. The gladius, so far as 

 he was able to examine it, presents some resemblance to the curious pen 

 elsewhere described (Chall, Ceph., p. 178). 



Dr Pfeffer's generic name being invalid, it would be necessary to change 

 the family name, which he has proposed (Hyaloteuthidse), to correspond with 

 the one which has the preference, but I think that for the present this form 

 may be placed among the Chiroteuthidfe.
