JMAMMALS OF ANGLO-EGYPTIAN SUDAN — SETZER 499 



Fasher, 1; Hamza, 1; El Fasher, 2; 110 miles east of El Fasher, 1; 

 Madu, 80 miles east of El Fasher, 1 ; 60 miles west of El Fasher, 2 ; 49 

 miles west-southwest of El Fasher, 3 ; 35 iniles west-southwest of El 

 Fasher, 1; near Ta^bo Hills, 1; 25 miles east of En Nahud, 2; Jebel 

 Meidob, 2. 



Measurements: An adult female from Umm Keddada, measures 

 as follows: Length of head and body 116; length of tail 151 ; length of 

 hind foot 29; length of ear 21; condyloincisive length of skull 31.3; 

 greatest length of skull 36.8; length of nasals 15.0; least interorbital 

 width 6.4; length of anterior palatine foramina 6.0; crown length of 

 upper toothrow 5.0; length of auditory bullae 10.4; depth of skull at 

 level of auditory bullae 14.1; breadth of braincase 16.6. 



Remarks: Intergradation with T. e. rufus is noted in the two speci- 

 mens from near En Nahud in the intermediacy of color and in the 

 shape and degree of inflation of the auditory bullae. The same 

 characters indicate intergradation in the specimens from west- 

 southwest of El Fasher with clivosus.

 Gerbillus (Taterina) lorenzi Wettstein, Anz. K. Akad. Wiss. Wien, Math.-Nat., 



vol. 53, p. 152, 1916. (El Obeid.) 



Specimens Examined: Twenty-two, all in BM, from: 20 miles 

 west of El Obeid, 1; 50 miles west of El Obeid, 4; Agur, 6; Nuba 

 Mountains, 5 ; Delaini, 5 ; Um Dona, 1 . 



Measurements: An adult male from 20 miles west of El Obeid, 

 measures as follows: Length of head and body 130; length of tail 175: 

 length of hind foot 32 ; length of ear 21 ; condyloincisive length of skull 

 33.0; length of nasals 15.6; least interorbital Viadth 6.9; length of 

 anterior palatine foramina 7.1; crown length of upper toothrow 5.1 ; 

 length of auditory bullae 10.1; depth of skull at level of auditory 

 bullae 14.5; breadth of braincase 16.4. 



Remarks: Specimens from the Nuba Mountains appear to be 

 intermediate in several characters between T. e. hutleri and T. e. rufus. 

 This intermediacy is demonstrated in the color of the pelage and the 

 size and shape of the auditory bullae. In all other characters of the 

 skull, though, they are more nearly like rufus. 



The five specimens from Delami appear to be intergrades in color 

 and size with T. e. anthonyi. 



Hatt (1934, p. 3) states that specimens from 50 miles west of El 

 Obeid are in many respects intermediate between T. e. hutleri and 

 T. e. anthonyi. Apparently Hatt overlooked the paper by Wettstein
