enough specimens to be sure that these are really constant. I am 

 almost sure that two well-marked subspecies are here represented — 

 the Uganda and Guas Ngishu form, and the dark Kavirondo GuK 

 race. The type of ansorgei is doubtless somewhat intermediate but 

 nearest the Kavirondo form. 



LOPHUROMYS ANSORGEI PYRRHUS HeUer. 



Plate 30. 



1911. Lophuromys pyrrhus Heller, Smithsonian Misc. Coll., vol. 56. No. 17, 

 p. 10. February 28. (Rhino Camp, Lado Enclave; type in U. S. Nat. 

 Mus.) 



Specimens.— Nine, including 3 in alcohol and 1 odd skull, as follows : 



Lado: Rhino Camp (Loring). 



This form is closely related to true ansorgei but averages brighter 

 and richer colored, with much more intensely colored underparts. The 

 skulls appear to average smaller, but there is not a really old specimen 

 in the series, so the limits of its growth are unknown. This race seems 

 to be restricted to the western side of the Nile.
