540 PROCEEDINGS OF THE NATIONAL MUSEUM vol. loa 



It is apparent that these animals from the Imatong Mountains are 

 different from any of the surrounding kinds, but owing to the broken 

 condition of the skulls and there being only the two specimens I feel 

 it best to identify them only at the specific level. 



Dendromus pumilio lineatus Heller 



Dendromus lineatus Heller, Smithsonian Misc. Coll., vol. 56, No. 17, p. 4, Feb. 

 28, 1911. (Rhino Camp, Lado Enclave.) 



Specimens Examined: Eight, from: Lokwi, 25 miles south of Torit, 

 3; Obbo, 4; Loa, 18 miles north of Nimule, 1 (MCZ). 



Measurements: An adult male from Loa and an adult female 

 from Lokwi measure, respectively, as follows: Length of head and 

 body 64, 58; length of tail 87, 85; length of hind foot 18, 17; length of 

 ear 10, 9; greatest length of skull 20.5, 20.2; condyloincisive length 

 18.5, 17.9; least interorbital width 3.2, 3.2; length of nasals 7.5, 7.6; 

 width of rostrum at level of antorbital foramen 2.5, 2.6; crown length 

 of upper toothrow 3.3, 3.2. 



Remarks: The type spccuiien of D. p. lineatus has a pronounced 

 middorsal black stripe. None of the specimens in the present series 

 shows this intense black stripe, but all agree with the remainder of 

 the type series of lineatus in showing only a faint suggestion of this 

 marking. It is quite apparent that Heller selected the most strik- 

 ingly marked specimen, rather than an average one, to name as the 

 type. 



In referring lineatus to D. pumilio I am accepting the work of 

 Bohmann (1942).

Steatomys aquilo Thomas and Hinton, Free. Zool. Soc. London, p. 264, July 6, 

 1923. (Niurmya, Jebel Marra.) 



Specimen Examined: The type. 



Measurements: Only external measurements are available for 

 this species since the skull is badly broken. Those measurements of 

 the type are as follows: Length of head and body 69; length of tail 

 39; length of hind foot 14; length of ear 13. 



Remarks: The color is light brownish gray above, gradually 

 merging over the sides into the pure white of the belly. The tail is 

 markedly bicolor, being of the color of the body above and white 

 below. 



No accurate comments can be made about the relationships of this 

 species since it is known only from the type, the skull of which is 

 badly broken.
