liiiii (UvNCL in which no stripes are found. except tliat the 

 lower longitudina] band is indicated by a row of spöts. This 

 form has a short-haired neck. Very little is known about it 

 as vet. Tlie abyssinian TrageJaphus decula of RirrELL has. 

 as a rule. no traces of vertical stripes. bnt a continuoiis upper 

 Umgitudinal band. and a row of spöts representing the k)wer 

 one. Tlie dorsal crest is dark, and the neek is well-haired. 

 TrageJaphus meneUki O. Neumann from the mountains of the 

 interiör Somah-Umd has no stripes at all, and only a fe^^ 

 faint spöts on the hindquarters. but unhke the South African 

 sulvatkns it has only traces of wliite in the dorsal crest be- 

 iiind. Its neek is well-haired. From the Hauascli Valley. 

 Abyssinia. the same author has deseribed another Buslibuek. 

 T. muJticolor, with well developed black crest. black under 

 parts, no stripes. but four white spöts on the hindquarters. 

 and with short-haired neck. 



Tragelaphus nigrinotatns O. Neu^iann from the interiör 

 Somali-land (at Borssa River, a tributarv to Lake Stephanie) 

 is only known from a female specimen without stripes, but 

 with numerous white spöts on the hindquarters, and a large. 

 brownish black saddle-mark on the back. T. delamerei Po- 

 COCK is also only known from a female specimen from the 

 ^omali-land, completely witliout spöts and stripes on the 

 dark yeljowish brown body. The la t ter has a collar of short 

 hairs round the neck, the former not. 



There are, as may be seen from this. a great number 

 of Bushbucks deseribed from different parts of Africa, and 

 there are probably ma ny yet unknown. To group all tlie 

 different geographical forms naturalJy. according to affinity 

 seems, at the present, verv difficult, although it is easy to 

 see that some of them are more closely related than the 

 others. O. Neumann has tried (1. c.) to divide them into 

 t^^o groups, according to the condition of the neck, viz. if 

 it was well-haired. or short-haired, at least to such an extent 

 that all specimens ha ve »cine mehr öder weniger kahle nur 

 mit kurzen Haaren bestandene Stelle, die nach Alter und 

 Geschlecht teils grösser teils kleiner ist.» To the former 

 group he counts T. sylvaticns, meneliki, delamerei and ^>pro- 

 bably^> decula and nigronofatus ; to the latter T. scriptus phale- 

 ratus, or}iafus. hor, dama. mnlticolor. iiiasaicus and rov.aleynei. 

 This grouping of the races with the aid of the characteristic 

 mentioned does not seem. however. to be correct so that the
