and progresses from behind forward, the new hairs coining in 

 uniformly and not in irregular patches as in summer molt. The 

 winter molt succeeds the summer molt so soon that the summer 

 pelage has not had time to become much worn ; consequently, 

 at this season, such shabby specimens as those commonly found 

 at the end of the breeding season are unknown.

4. REMARKS ON THE TOWNSENDI GROUP. 



EiUamias townsendi and its relatives are the largest and darkest 

 members of the genus. They inhabit the Pacific coast region 

 from southwestern British Columbia (Westminster and the Mt. 

 Baker range) southward to the Cuyamaca Mts. in extreme south 

 ern California ; and if. as seems probable, E. obscurusis a member 

 of the same series, the range will be extended to San Pedro Martir 

 Mt. in Lower California. No member of the group is known from 

 any point east of the east base of the Cascade-Sierra system. 

 The group comprises five forms, all but one of which seem worthy 



*This list does not include the three new extralimital forms described 

 in the present paper (palmeri, p. 208 ; oreowtex, p. 207 ; and dorsalis utah- 

 ensis, p. 210).
