3 Architeuthis dux is refevreä to this genus and A. mönachus with a query; hence A. dux is thetype; neither 
is characterised. — A note on the orthography of this name seems advisahle. By most writers it has been speit Archi- 
teuthis and, curiously enough, this is the form in which it was first published by Steenstrup. This would seem, however ? 
to have been a printer’s error, for in all his subsequent writings it is speit Architeuthus and in Oversigt K. D. Vid. 
Selsk. Forh., p. 1, 1881, he expressly States: — „jeg ikke har kaldt Slaegten med det forste Navn [ Architeuthis] 
men med det sidste [Architeuthus].“ 
4 Argonauta: two species are mentioned by Linn6, A.argo and A.cymbium; the latter is diagnosed only by 
reference to a figure of Gualtieri which represents a Shell so minute that it is impossible to identify it with any adult 
form: it seems necessary, therefore, to regard the first-mentioned species A.argo as the type. 
5 Bathyteuthis was published in the Narrative of the voyage of H. M. S. “Challenger” in May, 1885; 
Benthoteuthis was published in Trans. Connecticut Acad,, vol. 6, part. 2, in July, 1885,
