 Begründung zum Genus Procerodes. 



5. B ö h m i g führt Fovia trilobata unter „Ungenügend charak- 

 terisierte Genera und Species" auf. 



Für diese Art gilt, wie für vorige, daß die Einverleibung derselben 

 in das Genus Procerodes infolge der Unhaltbarkeit des Genus Fovia 

 (p. 45) nur einen Notbehelf darstellen kann. 



Geographische Verbreitung: Avatscha, Kam- 

 schatka (Stimpson 1857).

 and posterior extremities rounded. Small species, reddish brown, 

 found on the shores of Boston Harbour. Not commun.",:; jV*^ ^ 



Von diesen kurzen Angaben dürfte die, daß auch das Vorderende 

 rund sei, nicht ganz zutreffend sein. 



2. ,,. . I found within the body living youngs, 

 larvae, the form of which very much resembled that of the füll 

 grown animal, with the single difference that the anterior extremity 

 was less obtuse. There were as yet traces of eye specks. The 

 whole body of these larvae appeared to be composed of cellular 

 substance, and was surrounded by vibratory cilia. A central 

 transparent channel, probably the alimentary tube under its 

 most simple form, was seen extending to whole length the body.
