 tlie (lenoniination of certain limbs, especially with reyard to the three posterior ones. This is 

 due to a great extent to the very fact that the functions and not the homology of these organs 

 have been taken as a basis for the terminology. Thus .). 1). D.WA. the first writer to interpret 

 the appendages of the (' v j) i- i d i n i d s correctly, names the three posterior limbs as follows

 Onlv in the case of the last two pairs of limbs in the Cypridinids are there variations 

 in this work: these limbs are called either the next to the last and the last pairs of limbs or 

 the first and the last pairs of limbs. 



The terminology of the appendages used by G. W. Mt'LLi:i! in his large monogra])h of

 the special ])art of this work the three limbs in <piestion are called:
