170 EINAR LONNBERG, MAMMALS COLLECTED BY THE SWEDISH ZOOLOGICAL EXPEDITION ETC. 



Banded Grant Gazelle, 0. g. notata is probably an inhabitant only of somewhat higher 

 altitudes, the Loroghi mountains etc., and does not descend on the hot and arid 

 plains, resp. thornbush country. Its longer fur and richer colouration speaks for 



such a theory. 



HoLLiSTER has recently recorded' this race from the Laikipia plateau and also 

 given the measurement of a skull which had a condylobasal length of 260 mm., thus 

 larger than that of the pale race described above, but the author quoted says » there 

 appear to be no constant cranial characters by which skulls without horns* of this 

 and the typical race can be separated. The horns are different, however, he says, 

 » spreading but little at the points ». The distance between the points is recorded to 

 be 16 cm., thus the same as in one of my specimens from Lekiundu. There is thus 

 in this respect as well intergrading specimens to be found. 



The Grant gazelles are rather common on the acacia steppe south of Guaso 

 Nyiri. They occurred usually in small flocks, but single as well bucks as females are 

 often seen. In the thornbush on the northern side of the river they were less nume- 

 rous. In consequence of their pale colour and short, smooth fur they appeared 

 quite white in some shades of light. 



Lithocranius walleri (Beooke). 



ScLATEB & Thomas: Book of Antelopes Vol. HI, p. 229. 



The type locality of the species is said to be the Tsavo plains east of Kiliman- 

 jaro. The specimens from Somaliland which already then were known to be larger, 

 were named » Lithocranius sclateri-o by O. Neumann.^ The distinguishing characteris- 

 tics are said to be, in addition to the difference in size, as follows: The typical 

 L. walleri is said to be »redder» (»rother») than the Somali-race. It shall have black 

 knee-tufts (»schwarze Kniebiischel » ) and »das weisse der Unterseite bildet an den Seiten 

 des Schwanzes einen undeutlichen breiten Fleck*. On the other hand, the Somali- 

 race is said to have »braune Kniebiischel, und das weisse def Unterseite zieht sich 

 seitlich des Schwanzes als feine weisse Linie aufwarts». 



Looking at my three specimens from the northern side of Guaso Nyiri I find 

 that the upper central parts of the knee-tufts are black, but the lower and lateral 

 parts are rufous. It is thus difficult to know whether this characteristic shall indi- 

 cate L. walleri, or L. sclateri. The white along the posterior edge of the hams extends 

 as a fine line to the root of the tail, where it expands to a maximum breadth of about 

 1 cm. in the doe, about 2 cm. in the buck. It is difficult to know what Neumann 

 means with his words » einen undeutlichen breiten Fleck », which should be charac- 

 teristic of L. walleri, but it appears most probable that my specimens in this respect 

 as well are intermediate, between the northern and southern races. The name ^ scla- 

 teri i> can thus only be regarded to have subspecific value.
