This description is taken from ' ; Brit. Hy. Zooph." (Hincks) 

 where it applies to C. radiatum, and modified to suit the present 

 specimen, which differs from G. radiatum in the following respects : — 



C. radiatum. C. — Sp. I 



Suctorial appendages, usually 3 in One only.

The four sense organs were very large clear spheres, with a 

 small opaque white spot. 



In habits the medusoid strongly resembled C. radiation ; it 

 ' ; frequently fixes itself firmly by means of its suckers, and the arms 

 are thrown back and stand erect around the umbrella. It swims 

 b}^ short and rapid jerks, and when in motion the tentacles are 

 closely retracted/' 



Unfortunately the medusoid did not survive long, so that it 

 was impossible to make any further observations on its develop- 

 ment. It may have been a young example of G. radiatum, in which 

 the additional radial canals, suctorial appendages, and the branches 

 of the tentacles had not yet developed ; but on the other hand, the 

 medusoid was large and apparently well developed, the bell 

 measuring To mm. in height, and possessed double the number of 

 arms present in G. radiatum. 



While the species is doubtful, the genus in which this medusoid 

 must be placed can only be Cladonema ; I can find no previous 

 records of a Cladonema having been found so far north.
