Baird (/. c. p. 108, footnote) states that he retains the genus Sternasjns 
amongst the Gephyrea, as, in outward form at least, it seems to be more 
nearly allied to this group than to the true Annelids. 
Phoronis hippocrepia, St. Wright. Kowalevsky has published a treatise on 
the anatomy and development of this form. This memoir is printed in the 
Russian tongue, and we have been quite unable to obtain a copy of it. In 
a footnote to page 6 of the same author’s memoir “ On the development of 
simple Ascidia,” he mentions that the alimentary canal in Phoronis is built 
up just as is indicated among the Ascidia, that from its first pushing in of 
itself (Einstulpung) there appears an opening, which is the amis, and that 
after this the oral opening makes its appearance. 
The Phoronis is nothing else but the Sipuncuhis-ionxi from wliicli, accord- 
ing to Schneider, Krohn, and Claparede, Actinotrocha is derived. 
In a footnote to the Annelids of the Gulf of Naples, Claparede alludes to 
this discovery, /. c. p. 409.
