of the sycamore fig-tree. The Deculas pair in the month of May in this 
district, and produce their young ones in October. ‘They are very quick and 
shy, but are occasionally hunted by the natives with dogs. ‘Their flesh, 
according to Rippell, is not particularly palatable. 
The only other African explorer that appears to have come across this 
Antelope in its native wilds is Heuglin, who, however, does not favour us with 
a very distinct account of his experiences of it. In his memoir on the 
Antelopes and Buffaloes of North-east Africa, published in 1863, Heuglin 
states that the range of this species extends over the districts of Upper Nubia 
bordering on Abyssinia, Galabat, the River Settite, and Takeh. He also gives 
a figure of the skull of a specimen obtained by him, which he points out 
differs slightly in the shape of the horns from that figured by Riippell and in 
some other particulars. In a subsequent work (‘ Reise in Nordost-Afrika’) 
Heuglin has described what he considered to be possibly a different animal 
(although closely allied to the Abyssinian 7. decula) from the banks of the 
White Nile, where it is called by the Djengs “Bor,” in Bonga “ Towa,” 
and by the Dgurs “ Burah.” ‘This Antelope he met with in pairs amongst 
the high grass and thick bushes of Bauhinia and Acacia-trees in the 
above-named districts. In case of its proving different from 7. decula he 
proposed to designate it Tragelaphus bor. 
As will be seen by our subsequent remarks, it is not quite certain which of 
the species of this group of Zragelaphus occurs on the White Nile. It may 
be either the present 7. decula or one of the forms of 7. scriptus. 
In the British Museum there is a skin of an immature male of this species, 
together with its skull, belonging to the series obtained by Rippell in 
Abyssinia. ‘There arealso in the National Collection an adult mounted male 
and female from the Upper Atbara obtained in 1874 and 1876. 
Our illustration (Plate LXXXVIII.), which was put upon the stone by 
Mr. Smit from a sketch prepared by Mr. Wolf under the directions of the 
late Sir Victor Brooke, is believed to have been taken from the mounted 
specimens in the British Museum. 
So far as we know, no examples of this form of the Bushbuck have ever 
been brought to Europe alive.
