260 SMITHSONIAN MISCELLANEOUS COLLECTIONS [vOL. 45 



(op. cit.) : " There are not, so far as I am aware, any Cyclostomatous 

 Polyzoa which may be considered as truly stoloniferous. vSome of 

 the Hydrozoa are, but I know of none whose stolons are adherent 

 to stone or shell, such as are found in these ancient rocks ; neither 

 am I aware that the stoloniferous Ctenostomatous Polyzoa are ad- 

 herent to stone or shell, like Ascodictyon or Rhopalonaria. Yet it 

 seems to me that we have in Ascodictyon Uliformc, at least, primitive 

 representatives of stoloniferous VesictdariidcB, such as Vesicularia 

 or Bowerhankia, or possibly some member of the more humble race 

 of the Entoprocta. Barrois has spoken of a pro-Bryozoan race, 

 composed of free swimming organisms. May Ascodictyon be the 

 attached or larval form of some of the as yet unknown pre-Upper 

 Silurian types of organic life, polyzoan or otherwise ? " The name 

 Rhopalonaria hotellns is suggested for a new type of these fossils. 



In 1887, in a paper entitled " Notes on the Polyzoa of the Wenlock 

 Shales, etc.,"^ Vine gives further figures and descriptions of pre- 

 viously known Wenlock species of Ascodictyon and Rhopalonaria. 

 In this paper the " Ascodictyje " are referred to the Stomatoporidce, 

 which are Cyclostomata. 



Terebripora capillaris Dollfus and T. vctusta new species are de- 

 scribed by Oehlert in 1888 in an article entitled " Description de 

 Ouelques Especes Devoniennes du Departement de la Mayenne."^ 

 Both species are apparently Ctenostomata of the genus Rhopalonaria, 

 although we refer the latter doubtfully to this genus. Another for- 

 eign species which we doubtfully refer to Rhopalonaria is Entohia 

 antiqua described by Portlock in 1843.* 



In March, 1890,* Ulrich proposed a new genus, Vinella, " for an 

 adnate form supposed to be a Ctenostomatous bryozoan, with rela- 

 tions to Vesicularia Thompson, and probably also to Mimosella 

 Hincks." The fossil remains described and illustrated in this paper 

 were interpreted as representing " the stoloniferous part of the 

 bryozoan only," the zocEcia themselves being regarded as " having 

 been deciduous and developed by budding from the creeping stolons 

 at the parts now represented by small pores." Vine is credited as 

 being the first to' suggest the relation of Rhopalonaria and Asco- 

 dictyon to the Ctenostomatous Bryozoa.
