JIah. and tjipe as above. 



Tills species is a southern representative of the Ph. Ilaggardi 

 of Ecuador, from which it differs in various cranial details 

 and notably its stouter incisors. Its shorter tooth-row 

 separates it from Ph. osihe^ Allen. Mr. Simons's former 

 collections from La Paz and other localities in N.W. Bolivia 

 also contain specimens apparently referable to this form.

E. griseojiuva group. 



General culour of the type as in that of E. cachiria, Allen*,

* riiyllUis cachinus, Allen, Bull. Am. ISIus. N. II. xiv. p. 40'J (1901). 

 Ou renewed exiiniiiiatiun I am inclined .still to adliere to the view I put 

 forward in IH'.'b (1*. Z. S. 1898, p. 210), that tiie yrineii/iarus group is 

 really more allied to EUyvtodontia than to the more or less hypsoduut 

 Phyllotis.
