The White-Bearded Gnu, (_Connochaetes albojubatus_), is noticeably larger than the white-tailed species, and in some respects it presents a finer appearance. Its bulk is considerably greater, and its color is more pleasing. This species bears a strong resemblance to the third species, which is known as the Brindled or Blue Gnu, (_Connochaetes taurinus_), from which the former is distinguished by its white mane and jaw-tufts, and generally paler color. At wide intervals the White-Bearded species inhabits southern East Africa, from about S. Lat. 23°, to the Albert Nyanza and Lake Rudolph, but chiefly near the coast. In only one locality do we learn of its occurrence west of the 30th meridian. To-day it is most numerous in German East Africa and the southern portions of Uganda. The Addax Antelope, (_Addax naso-maculatus_), is a spiral-horned antelope which inhabits the southern edge of the Sahara Desert from Dongola quite across Africa to Senegal. Its extremely broad and spreading hoofs betoken a dweller upon sand, and are strongly suggestive of the snow-shoe hoofs of the caribou. It is said that this animal is not to be taken without making a journey into the desert, with camels. The Leucoryx Antelope, (_Oryx leucoryx_), is the only member of its genus which has curved horns. Because of the length and very slight curvature of the horns, this species has by some writers been spoken of as the Sabre Antelope, and by a mischievous perversion that name has been turned into “Sable” Antelope, which refers to a totally different creature, (_Hippotragus niger_). Anyone who places an order for the purchase of a real Sable Antelope, and receives a Leucoryx instead of _Hippotragus niger_, is profoundly disappointed. This species is a desert habitant, and its home is the desert region of North Africa from Dongola to the Senegal country. It is breeding regularly here, and the offspring mature successfully. The largest Leucoryx horns on record measure 39⅝ inches. [Illustration: BEATRIX ANTELOPE] [Illustration: BLESSBOK] The Beisa Antelope, (_Oryx beisa_), is a good representative of the group of straight-horned antelopes found in the genus _Oryx_. Of all the long-horned species, the two Beisas and the Gemsbok of Africa, and the Beatrix of Arabia, are the only species possessed of horns that are practically straight from base to tip. The Gemsbok is the largest and most showy species, being painted like a harlequin, in a startling pattern of roan, black and white. The Beisa is a good second, however. The horns of all these antelopes grow to great length, and are excellent weapons for use in encounters with the smaller game-killing carnivores. The largest horns of record measure 40 inches. The Beisa inhabits eastern Central Africa, from Suakin on the Red Sea southward to the Equator.
