with a most convulsive-looking movement. I took a very hasty shot, and had the satisfaction of seeing the animal tumble over with a big splash in the water. It turned out, unfortunately, to be a doe, full-grown, with a young one at foot. I had shot my first Nakon, and I solemnly affirm it will certainly be my last, except under much more favourable circumstances. An attempt to bring out the carcase that night being utterly useless, two Makobas slept on the small island, and I myself turned back to the village, where I arrived long after midnight, and, although completely done up with fatigue, could not sleep a wink, owing to the myriads of mosquitoes which preyed on me the whole night long.” From Lake Ngami the little animal thus captured was carried by Mr. Nicolls and his companions in their waggon 800 miles to Kimberley, and thence brought by rail and steamer to London. On arrival at the Gardens it was placed in a sheltered compartment of the Gazelles’ sheds, in which the yard in front was covered with dried peat-fibre in order to suit its elongated hoofs. Accompanying the Secretary’s Report on the additions to the Society’s Menagerie in October 1890, in which its arrival was noticed, will be found a coloured plate by Mr. Smit, giving an accurate representation of the animal as it then appeared. The Sitatunga thus acquired quickly attained its full stature, and showing symptoms of readiness to breed, was placed, in 1894, in company with a male of the Congo species (_L. gratus_) which had been obtained by purchase from the Zoological Gardens, Hamburg, no male of its own species being available. From this union hybrids were born on February 12th, 1896, and on February 28th, 1897, being in each case of the female sex. The period of gestation was, in both cases, about seven months. The young animals in general appearance took after the colour of the female of _L. gratus_, being of a generally bright red colour with white lateral stripes and white spots on the haunches. Such a young one is well represented, along with its mother, in the background of our Plate XCIV. In June 1899 the Society were fortunate enough to obtain a fine adult male example of this Antelope from the Right Honourable Cecil J. Rhodes’s Park at Groot Schuur, near Capetown, from which the principal figure in our Plate XCIV. has been taken. Mr. Rhodes kindly accepted in exchange for it one of the female hybrids above mentioned. The Society have therefore at present a unique pair of this scarce and beautiful Antelope in the Collection, besides the female hybrid born in 1896. The specimens in the National Collection referable to this form of the Sitatunga comprise two pairs of horns from the Chobé River (_Selous_), one pair of young horns from Lake Ngami (_J. A. Green_), the skin of an adult from the Zambesi (_Chapman_), and a pair of horns from Lake Mweru (_Crawshay_).
