*' There is some doubt as to the earliest spelling of this name. Both Phocena 
and Phocena were published in the same year, 1817. The former is given pref- 
erence as being in accord with the derivation and evidently the correct form, but 
Phocena is the spelling adopted by Linnzeus and some earlier authors for the name 
of the type species which doubtless suggested the designation of the genus.
