The species examined are Motella tricirrata and M. metadata , and the 
following facts have been observed : — 
1. An annular sinus which surrounds the eye. 
2. The co-existence of two subvertebral lymphatic trunks which traverse 
the canal formed by the baomapophysis. 
3. The existence of a longitudinal dorsal subjacent trunk, and of a cor- 
responding post-anal one, which is found in both Motella tricirrata 
and M. maculata.
