when adult ; the other having the arms equidistant and 30 

 to 60 tentacles per group. To these they applied the names 

 auricula and octoradiatus respectively. In a subsequent 

 paper (1878) on H. auricula {Sviithson. Contrib. K)iozvl., 

 vol. xxiii., 1881) Clark repeats that the number of tentacles 

 per group is about 100, but his figures show no more 

 than 30 to 35. Beaumont, after examining many specimens 

 from the coasts of England and Ireland, is of opinion that they 

 all belong to one species, the number of tentacles and other 

 characters varying according to age, etc. ; and for it he uses 

 the specific name auricula of Rathke — see his paper in Proc. 

 Roy. Irish Acad., 3rd ser., vol. v., p. 806, 1899, where the 

 matter is discussed at some length. For figures of H. 

 auricula reference may be made to Johnston's History of 

 British Zoophytes, 2nd ed., 1847, vol. i. p. 246. The author, 

 who was the well-known Berwick naturalist, does not say 

 where his specimens were obtained. Prof. MTntosh, 

 however, in his list of the Marine Invertebrates and Fishes 

 of St Andrews (1875), states that the species is locally 

 common on the coast there. 



In his second paper alluded to above, Clark compares 

 this stalked medusa to " a lady's parasolette heavily tasselled 

 at eight about equall\' distant points around the edge." 

 " Imagine," he says, " the parasolette turned inside out, so 

 that the usually concave under side becomes convex, and it 

 would then have the shape which our Lucernarian most 

 frequently assumes." American examples would appear to 

 attain rather larger dimensions than European ones. 



Rhizostonia octopus (1^.) = cuvieri, Gosse. — On 13 th 

 December 191 3, Mr VV. M. Ingles found a large Jelly-fish 

 stranded among the rocks west of North Berwick, and, 

 perceiving that it differed markedly from the common 

 species seen there, he carried it home and placed it in water 

 in his bath that he might examine it more carefully. 

 Comparing it with figures of Jelly-fishes in a book on 

 Natural History to which he had access, he confidently 

 referred it to Rhisostoma cuvieri, and at once wrote telling 

 me of the occurrence. Before I could visit him, however, 

 the fast decaying organism had been thrown out, so that I
