intermaxillary are much narrower than in that species, and altogether of the 
same shape as in V. kirki; and the entire prelacrymal part of the snout is 
narrower than in J. saltiana, which is especially striking in the lower view 
of the snout (figs. 2846 and 28c). Also with regard to the form and size of 
the nasal bones the new species is in some measure intermediate between 
the two other species. The suture, by which the nasals are united with the 
frontals, forms a much more obtuse angle than in J. saltiana, but is not a 
straight transverse line as in MV. kirki. The size of these bones is the same 
as in the Abyssinian species. ‘The hindermost molar of the lower jaw has a 
third lobe developed behind with a single enamel fold asin I. kirki. The 
nasal cavity seems to be as distensible as in the Abyssinian species.”’ 
Mr. Trimen furnished Sclater with the following information respecting 
this specimen :— 
“Tt was sent to me in March last from Damaraland by Mr. Eriksson, who 
has lately presented to us a male specimen. The Museum previously 
possessed a young male, also a Damaraland specimen, presented by the late 
Mr. James Chapman .... The colouring of the male and female is the 
same; but the adult male has straight horns 23 inches long, with prominent 
irregular ridges (seven in one example) circling their basal half. In the 
young male that we have the horns are 1 inch shorter, and there are only 
three undeveloped ridges. 
“‘ Mr. Eriksson informs me that this Antelope frequents rocky hills in the 
vicinity of Omaruru (about a degree north of Walvisch Bay), but is not easily 
procured, owing to its great agility among its stony haunts.” 
Judging from the localities it would appear highly probable that the Dik- 
diks obtained on the River Cunene by the well-known Portugese collector 
d’Anchieta, and referred by M. Barboza du Bocage to WM. saltiana, as also the 
skull in the Leyden Museum procured in Mossamedes by Mr. P. J. Van der 
Kellen, and assigned by Dr. Jentink in 1887 to “ Cephalophus hemphrichi- 
anus,’ will be found to belong to Madoqua damarensis, and that this species 
extends into the southern provinces of Angola, where the country is of the 
same character as in Damaraland, 
December, 1895.
