PHYLLODOCE GRCENLANDICA. 



87 



Body-wall with a comparatively thick coat of hypoderm under the cuticle, and 

 the circular muscular coat is well developed. The dorsal and ventral longitudinal 

 muscles are large, the former being almost separated by a median fissure, their outer 

 borders in section being very massive, whilst the ventral are somewhat ovoid. The 

 fasciculi in the ventral are flattened in transverse section, and almost all have their ends 

 placed externally and internally, the flat faces being parallel to each other. 



The oblique muscles meet or decussate beneath the nerve-cords, the circular coat, 

 the basement membrane, the hypoderm and cuticle being external. In certain sections 

 their attached ends widen into a broad fan.
