Oysters on the Coast of New South Wales. Rep. Aus. Mus. i, 
pp. 41-55, pis. iii-vi. 
An account of the ravages caused by Polydora ( Leucodora ) ciliata. The 
young worms do not bore through the shell of the oyster, but, as free- 
swimming larvae, are carried inside the oyster by the inhalent 
currents. The remedies are — (1) removal to fresh water, which kills 
the parasite, but is sometimes fatal to the oyster ; (2) careful drying of 
the oysters.

Wilson, E. B. The Origin of the Mesobla^t-bands in Annelids. J. Morph, 
iv, pp. 205-219, woodcuts. 
Work done chiefly on Nereis limbata and N. megalops. In them the 
mesoblast arises from a ventral plate, and is apparently ectoblastic, as in 
Lopadorhynchus. - But in reality all the ventral plate is segregated at the 
anterior end from two pro-teloblasts homologous with those in Clepsine. 
One of these teloblasts gives rise to the anterior part of the ventral plate, 
and is the origin of the mesoblast ; the other gives rise to the posterior 
part, from which come the neural plates, setaa sacs, &c. In this way the 
discrepancies of Lopadorhynchus come into relation with the usual telo- 
blasts of Annelid development.
