6. This communication between stalk and calyx, and the 

 continuity of muscle fibers from one part of the polypide to 

 the other, together with the oblique setting of the lopho- 

 phore, allies Myosoma rather closely with Loxosoma. 



7. The new species, Gonyj^odaria ramosa, is distin- 

 guished by the possession of a branching stalk. The 

 branches arise from any bulbous dilatation, and are of two 

 kinds, simple and stolonic, 



8. It is difficult to draw a real distinction between these 

 two kinds of branches. Transitions between them can 

 often be found. 



9. A septum is found below the calyx and above each 

 muscular dilatation of the stalk. A double septum is pro- 

 duced at the origin of a branch. 



10. That part of the branch which is enclosed by the 

 double septum may perhaps be homologous with a non- 

 polypide-bearing segment of the stolon. 



11. Regeneration of a stalk from the inner layer of cells 

 at the base of a muscular dilatation may take place, even 

 though the whole upper portion of the stem with the mus- 

 cular dilatation be broken away. 



V. Identification of Known Species. 



The following is a list of the species of Entoprocta found 

 on the Pacific Coast, which have been previously described. 

 The classification given by Ehlers has been followed.
