64 On neio Forms of Dendromus, Dipodillus, dec. 



number 76. Collected 11th July, 1904, by R. B. Woosnam. 

 Five specimens examined. 



This is the species quoted as Gerbillus paeba schinzi, ■'Noa.ck, 

 by Schwann *, who rightly identified it with Andersson's 

 Damara specimens so named by me some years before. But 

 in making that earlier determination I was clearly in error, 

 as Noack's animal was much larger, had naked metatarsals, 

 and was probably some form of Taterona. 



From G. paeba this gerbil is readily distinguishable by its 

 much paler colour, the complete inclusion of the fore-limbs 

 in the white body area, and its smaller bullae. 



Gerbillus paeba broomi, subsp. n. 



Paler than true paeba, the foot longer. 



Colour dark sandy fawn, intermediate between that of 

 G. calidus and of true paeba ; the hairs of the back pinkish 

 buff, heavily darkened by their brown or blackish tips ; the 

 sides clearer pinkish buff. Under surface as usual white, 

 but this does not pass across the fore limbs, as on the front 

 of these the body-colour runs down to the wrists. Face 

 rather greyer than body. Postorbital and postauricular light 

 patches present, but inconspicuous. Ears greyish with a 

 narrow brown edging. Hands and feet white ; soles hairy 

 to the same extent as described above in calidus. 



Dimensions of the type (measure 1 in the skin) : — 



Head and body 100 mm. ; tail 109 ; hind foot (wet) 28*5. 



Hab. Port Nolloth, Namaqualand. 



Type. B.M. no. 98.9.3.2. Collected September 1897 

 and presented to the National Museum by Dr. R. Broom. 



A paler form of Smith's G.p leba. There is in the Museum 

 collection an example of this group from Deelfontein, Central 

 Cape Colony, so closely matching Smith's type (which was 

 said to come from north of Latakoo) that I am disposed to 

 think some mistake was made by Smith as to the region 

 where his type was got. For north of Latakoo would have 

 been in the desert area, where the desert form G. calidus 

 occurs, while the type of paeba (which is also that of tenuis) 

 is of strong non-desert cinnamon-colour, very like the Deel- 

 fontein specimen. Possibly it was obtained on the way out 

 or home, as Smith passed, and that then it was wrongly 

 supposed to have been got at his farthest north.
