some new Species of Drawida. 533 



in D. somavarpalana, tlie nepliridia of this species do not 

 differ, from those of D. (/nrndis, of wliich we have a most 

 elaljorate account by Bourne. 



The Nervous System. — Both the cord and the oesophageal 

 nerve-mass siiow the same disposition of tlie histological 

 elements discussed under D. somavarpatana, and perhaps the 

 only feature wliich distinguishes D. j)aradoxa is the absence 

 of the large spherical centred cells occurring in the internodes 

 of the nerve-cord and also in oesophageal nerve-mass. Tiiis 

 primitive character of the nervous system, associated with the 

 presence of two pairs of testicular vesicles in two species of 

 Draioida, is a morphological fact worth calling attention to.
