 sides are more strongly tinged with fulvous. 



Lepus texianus griseusis very closely related to L. t. eremicus 

 Allen, from the southern border of Arizona ; it is a little grayer 

 (the dorsal area less suffused with brownish), but in size and 

 proportions there is apparently little, if any, difference. 1

1 I take this opportunity to correct an error in the original description of L. t. eremi- 

 cus (this Bulletin, VI, 1894, p. 348, last paragraph of the description), where, through 

 some inadvertence not now explicable, the measurements are quite wrong. The meas- 

 urements given for the type (/. c., p. 347) are correct, and the C9rrect measurements of 

 the series of 8 specimens will be found in Vol. VII, p. 202, op. cit.
