154 ANTHEAD.E. 



same time, if I were quite sure that the specimens in my 

 possession were identical with that described by Forbes, I 

 should be compelled to reject his specific name as involving 

 important error. The tentacles can in no sense be called 

 biserial : there are four distinct rows, which are regularly 

 graduated in length, and which show no other distinction ; 

 the appearance indicated by his figure (supposing it to 

 represent the present species) being quite illusory. 



But on examination I found peculiarities in the animal, 

 which required its generic separation. The most promi- 

 nent of these were its form, the length and flexuosity of its 

 tentacles, and its permanent expansion. In two of these 

 characters, as well as in several other points which I shall 

 presently notice, it manifested so close an affinity with 

 Anthea cereus, that I should not have hesitated to include 

 it as a second species in that genus, had not the presence of 

 acontta, and their extrusion through cincltdes, indicated a 

 nearer approach than is made by that species to the family 

 Sagartiadce. I therefore ventured to describe it under the 

 name oiAiptasia amacha ; the generic appellation referring 

 to its permanent expansion, from del, always, and irerdw, 

 to expand ; and the specific to the patience with which it 

 bore pushings and pokings without unsheathing its weapons, 

 from a, priv., and ixd-^o/xaL, to fight. The English name 

 refers to its trumpet-like form. 



Subsequently, however, I have found that the species has 

 been well described and figured by Mr. W. P. Cocks, in 

 his valuable List of the Actiniae of Falmouth, published in 

 the Eeport of the Cornwall Society for 1851, under the 

 title of Anthea Couchii, which specific name takes prece- 

 dence of mine. It is true, in his description, mention is 

 made of three white lines extending longitudinally up 

 the column, of which no trace exists in my specimens ; 

 but by a coloured drawing with which Mr. Cocks has
