"We also have a pretty species from Madagascar. It has 

 probably been named by Herr Saalmiiller or M. Mabille ; 

 but at present I cannot spare the time to look it up. Grote's 

 A. funeralis is unknown to me, but (if confounded with 

 A. americana) can hardly belong to the section Jochecera,

It is possible that one or two of the Japanese and Cliinese 

 forms enumerated above may be synonymous with species 

 described from East Siberia ; but the illustrations to the 

 * Lepidopteren Ost-Sibiriens ' and ' Keiscn und Forscliungen 

 im Amur-Lande' are so poor that, without seeing examples 

 from the Amur, it would not be possible to be certain of tiie 

 identity of the species, in a genus containing so many closely 

 related forms. 



LXV. — Notes on some Mexican Oryzomys. 

 By Oldfield Thomas. 



Dr. a. C. Bulleu has lately sent to the British Museum a 

 sjjecimen of an Oryzomys from Jalisco which appears to be 

 new and in working this out I find that some confusion 

 exists as to Alston's llesperomys Couesi, in clearing up which 

 a second species in the Museum collection proves to need 

 description.
