8 On account of the existence of the earlier name Megamys (Laurillard, 1848) applied to 

 another genus, Megalomys has been replaced by Moschomys Trouessart (Ann. Mag. Nat. Hist., 

 ser. 7 vol. 11, p. 388, April 1903; not of Billberg, 1828) and Moschophoromys Elliot (Field 

 Columb. Mus. Publ. 90, Zool. Ser., vol. 3, p. 270, Ma-. 7, 1904). This is not in accordance 

 with the provisions of the International Code of Zoological Nomenclature. See art. 36, with 

 accompanying recommendation; also Opinion 25 of the International Commission of Zoologi- 

 cal Nomenclature (Smithsonian Inst. Spec. Publ. 1938, pp. 59-61, July 1910). The name 

 Megalomus (Hall, 1852) differs in etymology as well as in form.
