Worms 75 



The bright orange or pink Lepralia or 

 Ross is very abundant on our west coast 

 and forms huge stony masses six feet 

 or more in diameter. Certain modified 

 individuals of this group occurring on 

 polyzoan colonies and termed Avicularia, 

 bear organs which have much the same 

 functions as the pincers of Echinoderms. 

 They bear a grotesque resemblance to 

 the skulls of birds of prey, the " skulls " 

 being mounted upon perpetually swaying 

 necks.
