NEW LITERATURE 
We have recently discussed poecilogony with 
regard to cnidarians and mentioned articles 
dealing with evidence of poecilogony in 
polychaetes. Krug (1998) reports on 
poecilogony in the small estuarine 
opisthobranch Alderia modesta. The species 
produces eggs of different sizes which yield 
either planktotrophic veligers, or lecithotrophic 
veligers depending on their available yolk 
supply. Back-crosses of these two forms yield 
the same ratio of reproductive types seen
