perns. The specimens of P. h. australis from Jalisco described by 

 Mr. G. S. Miller, Jr., had been long in alcohol and their exact color 

 is not known, no skins having been obtained, but if the measure- 

 ments given should be established by a series of specimens, it is 

 a smaller race than the one here described, and probably with a 

 different coloring. Additional material is riecessary before this 

 can be ascertained. 



MOSCHOPHOROMYS. 



In 1 88 1, Trouessart (Le Naturaliste, Paris, in, No. 45, p. 357) 

 proposed Megalomys as a generic name for Mus pilorides Desma- 

 rest from the Antilles. In 1903 (Ann. Mag. Nat. Hist., 7th Ser., 

 xi, pp. 387-388), he considered this term preoccupied by 

 Megamys (Dorbigny & Laurillard, Voy. Amer. Mend., in, 1842, 

 p. no, pi. xn, figs. 4-8, Paleontology), which, in accordance 

 with the rules of nomenclature prescribed by the International 

 Zoological Congresses, to be correctly spelled should stand as 

 Megalomys. He, therefore, proposed in its place the term Mos- 

 chomys. Unfortunately this name is preoccupied by Moschomys 

 Bellberg, Syn. Faun. Scandinaviae, i Mamm., Conspectus A, 

 1828, proposed for the Ondatra, Lace"pede Castor zibethicus, Linn., 

 and is not available. I, therefore, propose MOSCHOPHORO- 

 MYS, or Musk-bearing rat; ,ffxff, <f'f>tu, nun, with Mus desmaresti 

 Fisch(= Mus pilorides Desmarest), 8$ Oryzomys lucia Major as the 

 species, the former to be considered as the type.
