The measurements are summed up in Table I and are presented in 

 graphic form in figure 1. In addition, the biometric characteristics of 

 the two species are given in Table II. In making the calculations, the

have been followed. The writer makes no pretense to a comprehensive 

 biometric study of the two Sclerosporas but has used this method solely 

 as a means to the end of presenting the accompanying data as a basis
