Onchidiid^]. 
Bergh (15), from anatomical examination of several species, finds that 
the Onchidia resemble the Pulmonates in the structure of the nervous 
system, the presence of a lung, of a parenchymatous kidney, of the pecu¬ 
liar foot-gland, as well as in the relations of the genital organs ; they are 
thus not Nudibranchs, but Pulmonates, which have become adapted to 
an amphibious or marine life. Bergh’s view is opposed by von Jhering ;
