Sclater that the female of the pair had been received from the Jardin d’Acclimatation in March 1876, and the male in November 1879, and that both were believed to have come from Gaboon. The female had brought forth her young one on December 4th, 1880, after a period of gestation of 7 months and 24 days. A young male had likewise been born of the same mother in December 1881, but had not lived long. Besides those of Paris, several other Gardens in continental Europe have of late years obtained specimens of _Limnotragus gratus_, which, singularly enough, when we consider its habits in a state of nature, appears to thrive in captivity and to breed with facility. There are at present small herds of this species in the Zoological Gardens of Hamburg and Amsterdam. Dr. Kerbert, the Director of the last-named Garden, has kindly sent us for this work a list of the nine individuals bred in that establishment from 1891 to 1896, which is here subjoined:— Female covered. Young born. Sex. Period of gestation. ---------------------------------------------------------- days. 1. 18.4.91 26.12.91 ♂ 252 2. 31.7.91 28.3.92 ♂ 240 3. 26.5.92 5.2.93 ♀ 255 4. 3.7.92 17.3.93 ♂ 257 5. 21.6.93 4.3.94 ♂ 256 6. 22.6.93 7.3.94 ♂ 258 7. 9.7.94 15.3.95 ♂ 249 8. 30.8.94 6.5.95 ♀ 249 9. 25.5.95 24.1.96 ♀ 245 Dr. Kerbert observes that the colour of the young males and females when born is exactly like that of the mother, but that the sexes are easily distinguishable by the white hairs in the middle of the black stripe over the back in the males. The Zoological Society of London have not as yet been so successful in the treatment of this Antelope. They received their first female in 1885, but lost it. A male purchased in 1894 bred with the female _L. selousi_, as already mentioned, and produced two hybrids. A young female bred at Amsterdam, and received in September 1898, was lost shortly after its arrival. [Illustration: Fig. 113. Head of the male Congan Sitatunga, from the specimen in the British Museum. (P. Z. S. 1883, p. 36.) ] In our illustration of this species (Plate XCV.) the male has been drawn by Mr. Smit from the adult specimen above mentioned, now in the Zoological Society’s Gardens. The female, in the background, was drawn from the typical skin (now in the British Museum) upon which Sclater founded the species in 1880. The National Collection likewise contains a skin of an adult male (with horns) of this Antelope, obtained by Mr. du Chaillu in Gaboon, and a stuffed adult male from the same country obtained by purchase. From this last specimen the drawing of the head (fig. 113, p. 169) was taken by Mr. Smit in 1883. It has been kindly lent us for this work by the Zoological Society of London. _April_, 1900.
