Heller has recently created two new subspecies of this 

 Jackal.^ One of these from Kisumu, Brit East Africa, is 

 named »bweha» and is said to ha ve only »a few scattered 

 white hairs hidden among the black hairs of the tip» of the 

 tail. By this it differs very conspicuously from the present 

 specimens. »Bweha» appears also to have smaller dimensions 

 of tail and hind foot viz. 310 and 148 mm. in an adult male 

 constituting the type. The other subspecies »notatus» is from 

 the Loita Plains, Brit. East Africa. It is said to s>be distin- 

 guished from all other races by its white underparts». The 

 present specimens from Juja farm are all more or less over- 

 laid with ochraceous or buffish on the underparts, but just 

 because this is subject to variation, it might sometimes be 

 absent, and it seems hardly to suffice for the establishment 

 of a new subspecies, the less so as Heller found at the 

 type locality of notatus also a female v/hich had »a fulvous 

 wash on the underparts». He regards this colouration as a 

 sexual character. With regard to the present specimens this 

 is not confirmed, although one of the males is whiter than 

 the rest. Another difference between notatus and the typical 

 adustus according to Heller should consist therein that the 

 ears of the former were »drab», while those of the latter 

 were »russet». The ears of the present specimens are blackish 

 brown densely and finely sprinkled with whitish rings to 

 the hairs. By this a greyish brown general appearance is 

 produced. The ears of Sundevall's type specimens (rf-^ ?) 

 agree completely with those of the specimens from Juja farm 

 except that they are somewhat paler which may be due to 

 fading already during the lifetime of the animals because 

 their pelage is rather worn. Although the colour of the ears 

 of the types is not exactly »drab», it is much more like that 

 colour than »russet». It is possible that Heller has inter- 

 preted Sundevall's expression in his diagnose of Canis adus- 



^ Ought probably to be 755 !
