The method of formation of the embryo is that of concrescence by fusion from 

 before backward at the dorsal lip of the blastopore. The head of the frog lies on 

 that portion of the egg corresponding to the posterior portion of the body of the 

 fish. The posterior portion of the body of the frog lies over a portion of the egg 

 into which the body of the fish never extends.

, The duct is first represented by a columnar epithelium on the pronephros bet- 

 ween the nephrostomes extending backwards opposite the segmental duct. The 

 part covering the pronephros forms the mouth of the duct, the posterior portion 

 becoming thicker gives rise to a rod of cells forming the Müllerian duct. The 

 anterior portion is formed from coelomic epithelium ; the posterior part of the 

 segmental duct does not participate in the formation of the duct, not even by a 

 small part.
