Sphcerosyllis. Claparede (/. c. p. 204) emends the diagnosis of this genus 
as given in his ‘ Glanures,’ by substituting for the words ^‘the tentacular cirri” 
a single pair of tentacular cirri on the buccal segment.” This genus has 
not been correctly defined by either Quatrefages or Ehlers. S. pirifera, sp. n.,
