ITS FORM AND COLOUR. 95 



procure it, it was needful to bale out the water to that 

 depth, which I eflfected by the aid of one of my collect- 

 ing jars, and then to cut out the animal's cell with the 

 steel chisel. I was however sufficiently repaid for 

 the labour by the beauty of this snow-white Anemone. 



It does not appear to exceed f inch in diameter 

 when expanded; when contracted it is about the same 

 in height, and about J inch in thickness ; though by 

 more forcible contraction it becomes more globose. 

 In this state it is wrinkled both transversely and 

 longitudinally ; its colour is yellowish-brown, gradu- 

 ally merging into white on the basal half; the 

 porous suckers are also white, and are rather large, 

 and papillary. (See Plate I. fig. 8.) The number, 

 arrangement, and character, of the tentacles closely 

 agree with those of A. rosea, and, as in that and other 

 species, they are continued across the disk in lines 

 converging to the mouth. They do not appear how- 

 ever to be capable of distension, so as to become 

 diaphanous. The mouth forms a sort of conical tu- 

 bercle in the centre of the disk, the lips of which are 

 only slightly tumid, not protruded in lobes. The lips 

 do not appear to be crenated. The tentacles 

 and disk are opaque white, beautifully distinct, 

 without any markings, except that, when fully ex- 

 panded, a grey tinge spreads in a circle around the 

 disk, at the bases of the tentacles ; produced by the 

 degree of pellucidity of which the integment is capa- 

 ble, when filled with water. 



When much alarmed, as when we attempt to remove 

 it from its place of attachment, it discharges the con- 

 torted seminal filaments in unusual copiousness from
