BANA: 



The procedure aa outlined ia satisfactory for Bana pipiens from about September 1 

 until the normal breeding aeaaon of the species in April. The procedure for other species 

 of Anura is essentially the same except for the season, the dose of the hormone, and the 

 source of the hormone. 



The above table indicates that it is possible to secure Anuran eggs at any season of 

 the year, providing the appropriate species is chosen. Since there is also considerable 

 over-lapping of susceptible aeasona, material is available for hybridization expertments.
