" The polyps are irregularly disposed in a double row on each side of 

 the colony ; there is a median liare space on eacli side of the two flattened 

 faces. The verrucae are unequal in height, and stand at right angles to the 

 colony ; they are conical in shape ; the summit has a small opening which 

 shows a radiated structure." 



Duchassaing and Michelotti had, however, only a fragment devoid of 

 base ; the breadth was 5'5 mms., including the verrucae, the longest of which 

 were two mms. in height.

Colony simple, flexible; polyps in a single series on two sides, small, 

 adpressed to the stem, and directed upwards ; oval opening small, with a

Juncella barbadensis. 



Juncella barbadensis Duch. and Mich., p. 22, PI. v., figs. 5 and 6. 



Colony attached, simple, filiform, white ; polyps elongated with club- 

 shaped spicules ; verrucae in a single series on each side ; there is a distinct 

 median groove on each bare space. It is larger and more robust than 

 J. fimiculina ; the verrucae are larger.
