Two more types 

 of roving predatory 

 worms are shown in 

 the same illustration. 

 Of these, Phyllodoce 

 laminosa of the 

 French and English 

 coasts has as many 

 as three hundred to 

 four hundred seg- 

 ments, and may meas- 

 ure as much as two 

 feet in length; the par- 

 apodia are flattened 

 and leaf-like. During 

 the day these animals 

 lie quietly in their 

 hiding places, but 

 come forth at twilight 

 to swim about in 

 search of prey, when 

 the whole body, sup- 

 ported and in part 

 propelled by the 

 parapodia, executes 

 the most graceful 

 wave-like move- 

 ments. C shows a 

 species of the genus 

 Glycera, a compara- 

 tively dull colored 

 form, which habitu- 

 ally lies hidden in 

 sand'. These worms 

 make their burrows 

 by means of their 

 relatively colossal 

 proboscis, which is 

 studded with numer- 

 ous little warts and 

 teeth. From the 

 genus Glycera there
