Answer:
Large striped African antelope. There were 6 species but you'll have to check current status. Greater kudu 127 - 134 cms at shoulder. 270 kgs horns about 1 metre, open spiralled, (of at least 2 1/2 turns). long throat fringe and mane on the dorsal midline greyish fawn and 4 to 10 white transverse stripes. The others, all smaller: Lesser Kudu, Mountain Nyala, Nyala, Sittatunga and Bushbuck. Is this enough?
