7 According to Chun Eledonella is a synonym of Bolitaena. If this be the case Verrill’s name must stand, 
for Steenstrup in 1859 gave neither diagnosis nor type; the first definition was given in the “ Challenger ” Report in 1886. 
8 d’Orbigny includes the following in his Genus Enoploteuthis. 
E. leptura, 
E. morisii, removed to Abralia, 1849, 
E. molinae, type of Cucioteuthus, 1882, 
E. lesueurii, type of Ancistrochirus, 1849, 
E. armata, type of Abralia , 1849, 
E. subsagittata, fossil. 
9 Steenstrup enumerates three species E. morsei , stenodactyla and bursa as belonging to this genus, but does 
not specify a type; in default of any eyidence to the contrary I think it is proper to regard the species first named 
as the type and I venture to designate it as such to guard against any uncertainty in the future. 
10 The name is preoccupied in Aves (Blyth, 1863). 
11 Having examined the type of Haliphron in Copenhagen and that of Alloposus in Washington I am satisfied 
that these two names are Synonyms; Steenstrup’s phrase (like the flower of a Lily of the Valley Convallaria majalis), 
is not, I think, a valid diagnosis and therefore VerriH’s name must take precedence.
