authors regard the oxygenation of the perivisceral fluid as taking 
place through the thin integument covering the scale tubercles 
and the tubercles at the bases of the dorsal cirri, and having ob- 
served the scales to be subject to rhythmical movements by 
means of which a current of water is driven continually over the 
dorsal surface, thus renewing the water in contact with the 
“branchiez.” In species in which the felt-like dorsal covering 
does not exist, this function would appear to be in abeyance; 
in Polynoé and allied genera, so far as Mr. Haswell has observed, 
the elytra remain perfectly motionless, while the animal as a 
whole is at rest. i 
The sexual products reach the exterior through apertures in the 
bases of the parapodia ; and the ova are carried by ciliary action 
to the under surface of the scales, where they remain, adhering 
by means of a viscid matter till the embryos are well advanced. 
Impregnation probably takes place while the eggs are in this 
situation.—/ournal of Royal Microscopical Society.
