ACTINOMETRA CUMINGII. 



Actinometra ciiniingii 1887. Bell, Sci. Trans. Roy. Dublin Soc. (2), vol. 3, 



p. 645. 



Professor Bell records under this name an " Actinometra'' from Ceylon with 

 more than ten arms. He says '• This is typically a ten-armed species, but injury 

 and subsequent repair frequently lead to the development of a larger number 

 of arms." 



I have recently examined this specimen, which is preserved in the British 

 Museum, and I find it to be an example of the cumuion Cotnunthiis parvicirra.
