As the visitor will observe from the following enumeration of species, our collection of large and rare African and Asiatic antelopes is very rich. Unfortunately, until the completion of the Zebra House releases the apartments now occupied by the equines, a number of species which belong in the Antelope House must temporarily be quartered elsewhere. The Nubian or Three-Horned Giraffes, (_Giraffa camelopardalis_), are at present the most important and interesting animals in the building. The pair came from German East Africa, are now (April, 1913) about twelve years old, and cost $5,500. The male stands 14 feet 4 inches in height, and the female 12 feet 6 inches. Both are good-tempered animals, and have been in good health ever since their arrival. Their food consists of clover hay, broken forage-biscuits, an assortment of raw vegetables carefully cut into small pieces, a small quantity of bran, and rock salt. A study of the Giraffes reveals most interesting conditions. According to the point of view, the total number of species and subspecies may be reckoned at any number from three to six, inclusive. According to the specimens in hand, the Southern, or Two-Horned Giraffe, (_Giraffa capensis_), seems clearly defined from the Northern, or Three-Horned Giraffe, (_G. camelopardalis_). Next, the Somali Giraffe, (_G. reticulata_), of the Lake Rudolph region and northern British East Africa, seems fairly separable. At first the Five-Horned Giraffe, of western Uganda, seemed quite distinct, but now British naturalists hesitate about according to it rank as a separate species, because of its intergradation with the Nubian form, (_camelopardalis_). Judging from all evidence now available, it seems that the Giraffes of to-day represent the midway stage of an effort to develop several species from the parent stock, the Three-Horned Giraffe, which is the species here represented. The existing forms, including all species and subspecies, intergrade and run together in a manner that is fairly bewildering; but if the Giraffes could remain uninfluenced by man for a sufficiently long period the probabilities are that the species now branching off would be clearly established.
