NEW SPECIES OF RODENTS AND CARNIVORES FROM 

 EQUATORIAL AFRICA 



By EDMUND HELLER 

 Naturalist, Smithsonian African Expedition 



Further study of the mammals collected by the Smithsonian 

 African Expedition has made necessary the description of twenty- 

 one additional new forms which are dealt with in the present paper. 

 The bulk of these new forms are from Rhino Camp, in the Lado 

 Enclave. The specimens in the collection are the first which have 

 been obtained in this unknown region. The Lado Enclave com- 

 prises the Nile watershed lying west of the Upper Nile (Bahr-el- 

 Jebel). The precise geographical position of Rhino Camp is lati- 

 tude 2° 55' north, on the west bank of the Nile some fifteen miles 

 north of the station of Wadelai. 



This paper is the thirteenth dealing with the results of the expe- 

 dition. Incidentally a new Lophuromys from West Africa is here 

 described.
