Anthostoma of Schmarda. 
New species : — 
SphcRrodorum claparedii, GreefF, sp. n., 1 . c. p. 361, Taf. 6. GreefF amends 
the characters of the genus SphcBrodorum^ which includes S.Jlavum (CErst.), S. 
peripatus (Grube) peripatus (Johnston), as well as the new species 
from Dieppe. The new species is described in detail j and the cmious gland- 
like bodies, mistaken by Johnston for branchiae, are determined to be glan- 
dular capsules.

Leucodorea. 
Polydora, Bose {Leucodoray Johnst.). Agassiz {l.c. p. 323) shows that 
while Leucodora, Johnst., is the same as Poly dor a^ Bose, jQt Leucodora, Clap., 
is quite different from Polydora, Bose, and explains how this error arose, 
describing also the young of Polydora and figuring many of its stages.
