tical with the present species. He has figured a single 

 hydrotheca, which corresponds exactly with that of C. fra- 

 gilis ; and his description,, in all important points, agrees 

 with the one just given. He has noticed especially the 

 very minute size*.

STEM short, simple, rising from a slight bulbous expansion 

 of the stolon, ringed above and below, and bearing a 

 single calycle ; HYDROTHEC^: rather long and narrow, 

 tapering a little towards the base, and with 5 or 6 deep, 

 pointed crenulations round the margin; GONOTHEC^: 

 unknown. 



Height ^Q inch. 



A MINUTE species, with a slender calycle and a very small 

 number of marginal denticles. 



Dr. Strethill Wright has succeeded in rearing a Cam- 

 pannlarian from the planules of Thaumantias inconspicua 

 (Forbes) which bears a close resemblance to the present 

 species f. It is not improbable that C. raridentata may 

 prove to belong to the same genus.
