318 THE ZOOLOGIST. 



hall contained Paradise-fish (Macropodus viridi auratus), colours very vivid ; 

 Peacock-fish (Trichogaster fasciatus), in dazzling iridescence of green and 

 orange. The following amphibians were also shown : — Bombinator pachy- 

 pus, Rana esculenta, R. temporaria, Bufo calamita, Triton tceniatus, T. 

 alpestris, Salamandra maculosa ; also seven large Axolotls in a tank, 

 greyish green, marbled and mottled with darker green. 



A good Museum, the cases all painted white, was attached to the 

 Aquarium building, and contained a collection of Snakes and Tortoises, 

 well mounted in spirits, and also several other zoological collections. 



The Insect-house, close to the Bird-gallery, contained living insects, 

 such as Papilio machaon and large silk moths, in great variety, and in 

 various stages of metamorphosis. 



At Rotterdam, the Gardens, which are close to the Delftsche Poort 

 Station, possessed two examples of the Thibetan Black Wolf (Canis niger) ; 

 a very interesting Siberian Tiger, the fur of which was remarkably delicate, 

 the stripes being long and thin, and the whole animal presenting a pale 

 washed-out appearance, contrasting markedly with the darker coat of the 

 Malaccan Tiger in the next cage. 



The Eagle aviaries were fine and spacious, and the Heron pond of very 

 ample dimensions. It was curious to note that just outside the wires a 

 colony of free Herons had taken up their abode. 



The Antwerp Zoological Gardens, which are very fine, are close to the 

 principal railway-station ; admission one franc. The Monkey-house, a 

 handsome building, contained amongst its inmates a very rare and little 

 known Cercocebus from the Belgian Congo ; an example of Cercopithecus 

 brazzce (Brazza's Monkey), smaller apparently than the specimen in 

 London ; and many other animals. Perhaps the most curious building is 

 the Elephant-house, the front of which is decorated, in Egyptian fashion, 

 with figures of the Mountain Zebra and other animals painted on the out- 

 side. The Ungulates are well represented at Antwerp, the most note- 

 worthy being two Mountain Zebras (Equus zebra) ; a Giraffe (North African 

 form), protected from draughts by a huge sheet of plate-glass in front of its 

 cage ; a European Bison (Bos bonassus) ; two short-horned African Buffa- 

 loes, darker perhaps than normal (Bubalus pumiius) ; several American 

 Bison (Bos americanus) ; Malayan Tapir (Tapirus indicus), in the very best 

 health, as a glance at its beautiful coat testified ; Sable Antelope (Hippo- 

 tragus niger) ; Roan Antelope (H. equinus) ; Brindled Gnu (Connochcetes 

 taurina); Dama Gazelle (Gazella dama) ; Addax (Addax nasomaculatus) ; 

 and a Sumatran Rhinoceros (Rhinoceros sumatrensis). The Lions, Tigers, 

 and other large Carnivora were provided, as in London, with outdoor cages.
