Until lately the Inyala was believed to be restricted to the coast-lands of Eastern Africa south of the Zambesi. Recently, however, it has been discovered that this Antelope is likewise found further northward on the Upper Shiré, where it is known to the natives as the “Bō,” the _o_ being pronounced very long. Mr. Alfred Sharpe, C.B., on his return to England at the end of 1891, first brought home a single flat skin of the so-called “Bō,” which was identified by Sclater as belonging to the male of this species, and other specimens have since been obtained in the same district. Mr. Sharpe’s information was that it is found only in a piece of thick scrubby country bordering the Moanza River, which enters the Shiré on its right bank, near the Murchison Cataracts. In 1895 a fine specimen of this Antelope was forwarded to the British Museum by Mr. Gerald Oliver, R.N., of H.M.S. ‘Herald,’ with the following information in an accompanying letter:— “On the 5th of October, last year, I was shooting near a village called Mantana’s (lat. 16° 30´ S., long. 35° E.), about 7´ W. by S. of Chilomo, near the right bank of the Shiré River. Impala (_Æpyceros melampus_) are very plentiful about this particular spot, but I had not been able to get a shot at a good head. Later in the day, wanting meat, I decided to kill what I could, and coming across a solitary doe I fired. Great was the astonishment of myself and boys to find I had killed a female Inyala. I took the skin to Chilomo, and was told it was the first Inyala ever known to have been killed about these parts, and that it was practically an unknown animal there. “On the 26th of October, near the same spot, a male Inyala was killed by the then Surgeon of this ship. On the 29th of October I saw together 2 Inyalas and 8 Impalas. On the following day, at dusk, I met with and killed a solitary male Inyala, whose skin I forward. The natives were tremendously excited, dancing about and exclaiming ‘Bōōh,’ ‘Bōōh,’ the local name for the Inyala. They examined the body with great care. I was told in the village that the natives, on account of some superstition, would not touch the meat. Our bluejackets, however, ate it, and it was very good. The skin was _remarkably_ glossy and soft, and the hair was long under the neck.” In 1893 (see P. Z. S. 1893, p. 729) Sclater found a skull of this Antelope in one of Mr. Crawshay’s collections from the district of Lake Mweru, but we are not quite certain that it was actually obtained in that locality. Sir Harry Johnston, in his volume on ‘British Central Africa,’ sums up his information on this species as follows:—
