96 EINAR LONNBERG, MAMMALS COLLECTED IN CENTRAL AFRICA. 



that of the present collection, viz. with a maximum length of only 168 mm., a basal length 

 of 142 mm., orbit to muzzle 83,5 mm., length of nasals 53,3 mm. etc. 



Dollman's subspecies lutea from »N. E. Karamojo, Central Province, Uganda »^ 

 is described on an adult female as type. Unfortunately no adult male skull has been 

 measured of this race, but it appears to be rather large as the greatest length of the 

 female skull and some of its other dimensions are fully as gteat as, or more than those 

 of a male S. g. hindei. To judge from these facts it appears probable that the skull in 

 Capt. Arrheniits's collection can be referred to *8'. g. lutea. 



Roosevelt's and Heller's map over the »distribution of the races of bush duiker » 

 may need some modification in consequence of this. 



Hylamus harrisoni Thomas. 



1 ? Beni, Aug., Sept. 1914; 1 ? Masisi, Febr. 1914. 



The former is more vividly coloured than the latter which appears faded and appar- 

 ently is in the act of shedding its old hairs. The tail is above like the back, white beneath. 



The skull from Beni has a basal length of 94 mm. (the other is not quite fuUgrown), 

 distance from orbit to tip of premaxillary 47,5; length of nasals 33; greatest breadth of 

 the same 23, length of upper molar series 31,8 mm. These measurements are somewhat 

 smaller than those of the type, but this may be dependent on different sex, as probably 

 the female is smaller. 



Capt. Arrhenius has recorded in his diary that the specimen shot at Beni in the 

 Kisuahili language was called »Songola ». As this word, also spelt »Sungula », means a 

 Hare it apparently has been used to signify the small size, and perhaps also the horn- 

 less condition of the animal. 



Kobus defassa forma dianse Matschie. 



2 male head-skins and skulls from Rutshuru, ^"/^ 1914; 1 J", 1 ? complete and 

 a male skull. 



Although these specimens are from the same locality, as far as is known, they are 

 not quite identical with regard to their colour and pattern. The two head-skins have the 

 forehead )>fawn», but the white mark above the eye is much better developed in one 

 than in the other, and the one with smaller eye-spot has more black mixed in on the 

 lower cheeks etc. The large white spot on the throat does not extend laterally as far 

 as to the base of the ears. In the complete specimen the forehead is a little duller in 

 colour, somewhat approaching »burnt umber » (Rep. de CouL, 304, 1) without, however, 

 quite representing this colour. In this respect the specimen in question appears to re- 

 semble the specimens from Kasindi which Matschie has named ))cottonii>, but it differs 

 from those in having less white on the throat, so that this colour does not extend to the 

 base of the ears. The colour of the body is in correspondence with Matschie's descrip-
