Plectoteuthis, Owen, 1881. P. grandis, Owen, 1881 [monotypic] (— Architetithus). 
20 This is probably the young of some species of Abralia. 
21 From the definition Moschites is the same as Eledone Leach and must therefore take the type of that genus, 
which is Octopus moschatus Lamarck. 
22 There can be no reasonable doubt that this spelling is the result of a printer’s error and that the rectification 
to Octopodoteuthis made by Krohn in 1845 is fully justified. 
23 Although two species “0. carriboea” and “0. angulatus” are referred to by Lesueur, yet in as much as one 
is described and the other merely referred to, the former has every Claim to be regarded as the type; Teleoteuthis 
Verrill has precedence over this name which was preoccupied in Entomology. 
24 I regard this as a case of “type by original designation” because this species is described and figured from 
an actual specimen, whereas the others are merely based upon the more or less inadequate accounts of previous writers.
