158 REPORT ON NATIONAL MUSEUM. 



It has been found necessary to keep king-snakes apart from the others, as their canni- 

 balistic tendencies are well developed. 



In the months of September and October copulation was noticed between some fine 

 exami)les of the indigo snake (Spiloies ei-ebennua) in the vivarium, and it is aoped 

 young specimens may be secured as a result. 



In the basin of the fountain in the rotunda are kept living fishes of 

 the following species : 



1. Oyprinus carpio (Liun6). a scale carp ; h leather cari3. 



2. Carassius auratus (L.) Bleeker. Goldfish: a common form ; 6 triple- 



tail form. 



3. Hybrid between Nos. 1 and 2. 4. Idus melanotus (Hajckel). 



In a tank in the same room are shown two specimens of albino axo- 

 lotls {Siredon piscifortnis), which were bred by M. Carbonnier in Paris, 

 France, from other albinos which were the progeny of a pair of black 

 axolotls. 



Kearly all the living species of North American Testudinata are kept 

 in confinement in one of the smaller inclosures on the carp ponds on 

 Monument lot, where they remain for purposes of acclimation. 



Fishes of the following species are cultivated in the carj) ponds : 



1. Cyprinus carpio (Linn(5). a scale carp ; h mirror carp ; c leather carp. 



2. Idus melanotus (Haeckel). Leuciscus idus (Gthr.). ]!^erfling; Orfe; 



Golden Tench ; Ide. 3. Tinea vulgaris (Cuv.). Tench. 



These ponds are under the control of the Director of the Museum, and 

 the details of their management are described in his report as Commis- 

 sioner of Fisheries. Many American species of fish have also during a 

 part of the year been kept in aquarium tanks in the Armory Building, 

 where during the spring months extensive operations in connection 

 with the hatching of fish have been carried on, which have been wit- 

 nessed by large numbers of visitors.
