[21] CEPHALOPODS OF NORTHEASTERN COAST OF AMERICA. 231 



Moroteuthis robusta (Dall, sp.) Verrill. 



In this connection I may also refer to a gigantic Pacific Ocean species, 

 obtained by Mr. W. H. Dall, on the coast of Alaska, in 1872, which 

 will be described as fully as possible in another part, of this article, 

 when discussing the foreign species of large Cephalopods (see Plates 

 XIII and XIV). Three specimens were observed and measured by Mr. 

 Dall. The largest one measured, from the base of the arms to the end of 

 the body, 8.5 feet. The ends of all the arms had been destroyed in all the 

 specimens. It was originally t briefly described by me under Mr. Dall's 

 MSS. name, Ommastreplies robustus, but a more careful study of the 

 parts preserved, especially the 'cone' of the 'pen' and the odontophore, 

 convinced me that it belongs to the family Teulhidce, characterized 

 especially by having rows of sharp claws or hooks on the 'club' of the 

 tentacular arms, instead of suckers.! It was of special interest, to add 

 another generic type to the list of gigantic species.
