INDUCED BREEDING IN OTHER AMPHIBIA 



There is reason to believe that any amphibian which is sexually mature and which has not 

 recently undergone its normal breeding reaction, will respond to the pituitary hormone by 

 ovulation (female) or by the release of spermatozoa (male). In general, the Anura will 

 respond to pituitaries from other Amphibia but not from mammalian extracts of the pitu- 

 itary hormone. Exceptions to this statement are Bufo and Xenopus. The Urodela, in 

 contrast, will respond readily to the pituitary hormone from almost any source. 



There follows an alphabetical list of the more common Amphibia which have responded to 

 pituitary treatment in the manner described for Rana pipiens. The references given are 

 not complete but represent one of the major sources of other references for the particular 

 form.
