 two embryos of 14 and 20 mm. length and two older Amblystoma 

 of 7 and 10 cm. length respectively, the following table is given:

From these tables it will be seen that sometimes the right 

 and left medial rami are joined. The division of the common 

 medial ramus is into right and left branches. In their position
