SPECIMENS OF THE AXOLOTL, NEW YORK AQUARIUM. 



THE AXOLOTL. 



A photograph published in this number of the 

 Bulletin shows four specimens of the axolotl 

 (Atnblystoma mexicanum) Cope, which have lived 

 at the Aquarium for several years, growing consid- 

 erably during that time. This interesting amphibian 

 is a species in which it was long said the larval stage 

 was never passed, and it appears from experiments 

 that, if kept in the water continuously, it may retain 

 its gills indefinitely. It has been bred from eggs for 

 many years in European aquariums, and, like other 

 larval salamanders, may reproduce limbs that have 

 been cut off. 



It abounds in the lakes about the City of Mexico, 

 and is used for food, reaching a length of ten inches. 

 Species of the same genus, especially those found in 

 the United States, pass through a metamorphosis in 

 which the external gills are absorbed, and the animal 

 can live on land. 



Other interesting amphibians in the Aquarium col- 

 lection are the hellbender, of the Ohio valley ; the 

 mud puppy, of the Great Lakes; and the amphiuma, 

 of the Southern States. Specimens are promised of 

 a new and interesting blind genus (Typhlomolge), 

 which comes at times from the artesian well of the 

 United States Fish Commission station at San Mar- 

 cos, Texas.
