PHYLLODOCIDAE

Varietal characters. The only difference that I can find between these specimens 

 and a typical example of this species from northern 

 European waters is that in the elytra from the middle of the 

 body, on each side of the opening caused by the indentation 

 of the scale on its outer border, there are two or three fiUform 

 papillae (Fig. 15) not present in the northern form. More- 

 over, the bract above the neuropodium is more flattened 

 and tongue-shaped than in the stem-form and lacks the 

 terminal stylode. Otherwise, in the shape of the head, in 

 the form of the minute elytral vesicles and in the structure 

 of the feet and bristles these specimens are indistinguish- 

 able from the European form. 



I have not been able to compare the scales from the 

 anterior region of the body, for these are all lost from the 

 present specimens, which are in rather poor condition. They 

 are all incomplete and the largest measures 20 mm. by i mm. without the feet for about 

 80 chaetigers.
