38 MEMOIES OF THE QUEENSLAND MUSEUM. 



Genus MESEMBRIOMYS, Palmer, 1906.

 Wash., xix, p. 97.

Hapalotis hemileucura, described by Gray (P.Z.S., xxv, p. 243, 1857) and 

 illustrated by Gould (Austr. Mamm. iii, pi. iii), has not been incorporated by Oldfield 

 Thomas in his revised list, and is probably regarded as a synonym. Only a single 

 specimen was procured, Mr. A. R. McCulloch (Austrahan Museum) informs me that 

 it is hsted as a valid species in Trouessart's Catalogus Mammalium, i, 1897, p. 504. 

 Unfortunately, this work is not obtainable in Brisbane. 



Mesembriomys macrurus, Peters.

R. Collett (P.Z.S., 1897, p. 322) says there is much reason to believe that 

 Hapalotis boweri, Ramsay (P.L.S. N.S.W. (2), i, p. 1153, 1886), is identical with 

 macrurus.
