Obs. In Griffith’s ‘ Cuvier’ (vol. xiii. Annelida, pl. 4. fig. 2) there is 
a figure of our Leucodore ciliatus under the name of Spio seticornis. 
It is not said from what work this figure is copied. I cannot re- 
concile the description of the Spio seticornis of authors in general 
with the worm before us.
