The generic name MiirlUi Olicn' is hei-e re.ganhMl as a nomcn nmlum. in 

 common with all the other names proposed by Oken in this now famous 

 article .giving his own eipiivalents for the generic groniis in Cuvier's class- 

 ification. Oken's proposed eipiivalents seem not with siitficient definlteness 

 intro(hiced as substitutes. an<l. conseiiuently. ;ire not removed fi'om the cate- 

 gory of noinina nuda. The jiarticular name, llu'refore. whicli we liave now 

 under consideration we must re.jed for the gronj) of ducks to whicli it lias 

 been commonly applied, at least as dating from IMT. The next name in 

 ]>oint of time, which can he used for this group, seems to be Fulix Sunde- 

 \all.- It was originally proposed for tlu' '"Anate-; lobatae." to include all 

 the ducks with a lobed hind toe. but no species was mentioned, although 

 the group was stated to contain the generic groups Plfifi/pn-'^ Brehm. lliidro- 

 hatcH Temminck, and FuliyuUi "a P.onaparte acceptum". Professor S. F. 

 liainP was the first author to restrict FiiUx Sundevall to a definite modern 

 genus of ducks, and he circumscribed tlie group to include the American 

 species Anas marila Linnaeus. Fiilif/iild nffinis Eyton. and Anna cnlliiriH 

 Donovan, but at the same time implying that his type was one of their 

 European relatives. However, the tyjie of this group was later definitely 

 fixed by Baird. Hrewer and Hidgeway' in the following language: ''No 

 type designated, but restricted to the group of which Anas marihi. Linnaeus, 

 is typical, by Professor Baird in P.. \. Am. ISW. 700." There thus seems no 

 doubt of the propriety of using the name Fulix for the Scaup Ducks. The 

 term Xcttarioii Baird' is a name pr<iposed for the same group in cas*' tiie 

 designation FiiU.r Stnidevall could not properly be restricted as Professor 

 Baird intended.
