^ Oryzomys chrysomelas AUeii was originally recorded (Allen, Bull. Amer. mus. nat. 

 hist., Ill, p. 210, April 17, 1891) as Hesperomys [= Akodon ] califfhiosus Tomes. 



2 In 1894 Merriam published a partial revision of this group (Proc. acad. nat. sci. 

 Phila., 1894, pp. 225-2o2, September 24, 1894). 



3 The bushy-tailed species (X. cinerea and its allies) are regarded by Merriam (Proc. 

 biol. soc. Washington, viii, p. 112, July 31, 1893, and Proc. acad. nat. sci. Phila , 1894. 

 p. 242, September 24,1894) as forming the subgenus Teonorna Gray (List of the specimens 

 of mammalia in the British museum, p. 117, 1843). As the boundaries Ijetween this group 

 and typical Xeotoma have not been clearly defined, no attempt is here made to maintain 

 the distinction.
