Eine neue Form der Elenantilope. 



253 



inches along the curve, and thirty in a straight line from the base 

 to the tip. The distance of their ends is twenty-two inches. 

 A transverse section taken three inches from their base would 

 represent a triangle, the posterior side of which is slightly longer 

 than the outer one; at this portion the horn is broader from side 

 to side than from the front backwards. In about the middle of 

 the length of the horn the transverse section becomes an isosceles 

 triangle, passing into a circular shape in the last fourth of the 

 length. 



The trihedral shape of the basal half of the horn is produced 

 by a prominent, but obtuse ridge in front of the horn; this ridge 

 is in the median line at the base of the horn, runs then a little 

 inside of the median line for a short distance, and is finally directed 

 towards the outside of the horn, disappearing altogether in the 

 distal conical portion. The posterior side of the horn is remarkably 

 flat and broad. 



The annulations are distinct only in the basal portion and 

 very obscure further on, the distal half being smooth. . . 



Aus der Abbildung ist zu ersehen, daß die Hörner leicht nach 

 hinten gekrümmt und mit den äußersten Spitzen etwas nach innen 

 gebogen sind. 



Lydekker hat in The Field LXXVIII, 1891, 130 für dieses 

 Gehörn den Gattungsnamen Doratoceras vorgeschlagen, ist aber 

 neuerdings der Ansicht Sclater's beigetreten, daß es sich nur um 

 Hörn er einer weiblichen Elenantilope handele. 



Taurotragus oryx patter sonianus Lydekker, The Field CVIII. 

 1906, 579 ist begründet auf einen Kopf, den Colonel J. H. Pattersok, 

 wie 1. c. 609 gesagt wird, in Laikipia, nordwestlich vom Kenia 

 erbeutet hat. 



„There is an incomplete white chevron similar to, although 

 rather smaller than, the one found in the giant eland, while only 

 a narrow stripe in the middle line of the face, above and between 

 the eyes, is dark brown, the sides of the forehead being rufous. 

 On the lower part of the face there is a larger dark brown area 

 than in the ordinary eland, although there is a rufous fawn-colouri d 

 patch on each side above the nostril." 



In both the latter respects Colonel Patterson's specimen recalls 

 the giant eland, although it apparently lacks the dark white bordeml 

 band on the side of the neck charakteristic of the latter. 



Auf Seite 609 wird dann noch hinzugefügt: 



The striping of the body in very slight, the chief markings 

 being three unsymmetrical pairs of stripes on the withers.
