shape of a button and is firm to the touch, coriaceous, and of a deU- 

 cate yellow colour. 



The body is covered by an epidermis, which is easily detached and 

 slimy ; when this was rubbed off the animal was of a dirty white ; 

 the epidermis was replaced in a few days, when the animal recovered 

 its colour ; when portions only of the epidermis are rubbed off, it has 

 a mottled appearance. 



AVhen closed all the tentacles are completely withdrawn. 



The margin of the disk is crenated ; the tentacles are placed within it. 



The tentacles in the outer row are thirty-two in number ; the other 

 three rows have each two or three less ; there are four rows in all. 

 The tentacles in each row differ from the others ; those in the outer 

 row are the longest, then those of the second, third and fourth, in 

 the order that I have named them ; the third and fourth rows having 

 the peduncles so short as to be nearly sessile. The shape of the ten- 

 tacles, as 1 have stated, differs much. The rows of tentacula, as also 

 the individual tentacles, closely approximate ; those in the outer row 

 diverge slightly, and, when looked at from above, bear the appear- 

 ance of a finely-lobed edge to the disk, the real margin being hidden 

 by the heads of the tentacles hanging over it. The tentacles in each 

 row appear to the eye short, stout and capitate ; those in the first 

 or outer row have the head bilobed or kidney-shaped, and a round 

 tubercle placed below the head on the inner side ; all the tentacles are 

 horizontal. The tentacles of the second row are of a peculiar con- 

 struction, a])parently uniting the capitate extremities of Corynactis 

 with the elongated form of Actinia ; the apex is a spear-shaped pro- 

 cess, and this is seated on a peduncle formed by four globose bodies 

 placed two and two, and divided from each other by constrictions 

 more or less deep. In the third row' the peduncles of the tentacles 

 are very short, thick and capitate ; the crown is round, rather oblong, 

 and wdth a constriction at half the distance from each end, giving 

 the crown the appearance of a figure of 8. The fourth or innermost 

 row is short, or shorter than those in the third ; they are in fact nearly 

 sessile. The heads of the tentacles in the fourth row appear occa- 

 sionally to vary ; sometimes being of the same shape as those in the 

 third row, that is, bilobed, whilst at other times they are decidedly 

 five-lobed. The whole of the tentacula are straight, rigid, regularly 

 disposed, and point slightly outwards. They shghtly change their 

 shape at times when the animal is opening ; this however is not always 

 the case. 



The disk within the inner row of tentacles is ample. 



The mouth is formed of two crenated lips, forming a straight ori- 

 fice ; at times this is drawTi into the shape of a crescent. Whilst 

 copying this portion of my notes, my Corijnactis does not appear quite 

 easy ; it has thrown out its lobes, covering every part of the disk, 

 with the exception of the crenated margin ; the lobes do not rise, as 

 in species oi Actinia, above the margin ; they are on the contrary flat 

 and even with it, and are firm to the touch. 



The colour of the animal is a delicate yellow or buff. The disk 

 is of a pellucid white, streaked with fine radiatmg lines of a dead
