212 PELAGIC MFE, FALMOUTH. 



Norway and France. Drs. Bloclimann and Hilger ( 1 ) six years 

 ago published a very full anatomical description of this Actinian. 

 The most unique feature in connection with this species is its 

 mode of increase by transverse fission. 



The method is as follows : — an annular constriction appears 

 in the region of the posterior third ; buds being formed just 

 beneath this which eventually surround the mouth of the parent 

 and form the tentacles, meantime this constriction rapidly 

 increases, and the anterior portion is cast off, a perfect animal. 

 M. Sars once noticed three connected individuals. I have 

 carefully followed this interesting method of fission through 

 all its stages, and can fully confirm the statements of previous 

 investigators. There is one point, however, in the anatomy of 

 this animal to which I should like to direct special attention. 

 Drs. Blochmann and Hilger loc. cit record the presence of 

 " sixteen tentacles, in two rows of eight each." In my 

 specimens I find the number of these tentacles to vary exceed- 

 ingly. In three specimens I found the number of tentacles to 

 be as follows : 10, 11, and 16, respectively; and in a specimen 

 secured since my return from G-ermany only 14 tentacles were 

 present. I am now engaged in studying the anatomy of this 

 species of anemone, and I hope at some future date to offer some 

 further remarks on its anatomy. 



Polyzoa. On the 1 4th of July, Mr. Bealey gave me a stone 

 about four inches in diameter which he had obtained from some 

 long-line fishermen. He informed me "it was dragged up, off 

 the Lizard." I found attached to this stone, near the centre, a 

 beautiful specimen of PoreUa Isevis. In size it was unusually 

 large being Z^ cm. in height, and the spread of its branches 

 5 cm. 



There were no less than four specimens of the anemone 

 Caryophyllia Smithii on the same stone, and one Oaryophyllia 

 had upwards of seven specimens of the parasitic barnacle 

 Pyrgoma Anglicum on it. Mr. Q-osse says concerning this 

 barnacle as follows: — "two are sometimes found on the same 

 coral." 



Mollusca. On the 13th of January, when making my 

 periodical examination of the coal hulks moored near my hut,
