found on the Coast of Devon. 85 



Thus Troglodytes might be said to have two series, the alternate 

 ones being always on a lower plane ; or it might be described as 

 having four series. From this, and from the number of rows 

 varying with age, this character seems to me of little value in 

 the determination of species. 



A large variety of this kind, or perhaps a distinct species, 

 occurs sometimes, thrown upon the Teignmouth beach after 

 storms. The body of the specimen from which the following 

 description was taken is of a uniform gray colour, with a tinge 

 of buff. It is twice the usual size of Troylodytes, and in con- 

 traction assumes the same hemispherical form, though the body 

 is a little more elongated. In expansion it is cylindrical, but the 

 form changes much, sometimes becoming much lengthened, and 

 at others being constricted in the middle, so as to put on some- 

 what of an hour-glass sha})e. When expanded the mouth is 

 seen to be surrounded by a circle of yellow, bounded by a dark 

 line, and outside this is another yellow border, which is ended 

 by a wavy irregular line of blackish- brown ; this may be said to 

 mark the commencement of the tentacles. Outside this waved 

 line is a broader ring of black. If the appearance of these wdth 

 regard to one tentacle be described, the broader line forms the 

 base of two triangular figures, of which the waved line forms 

 the sides, the angle subtending the base pointing towards the 

 centre of the disc. Beyond this the tentacles are white, with 

 three rings of grayish-brown, and tipped with the same colour 

 at their summit. They are numerous, arranged in four rows, 

 thick, and proportionately shorter than in the typical Troglo- 

 dytes. Though the description and appearance of these two are 

 very much alike, there is an indescribable difference between 

 them, which makes me unwilling to regard them as certainly the 

 same. The larger variety expands only in the dark, and is 

 found thrown upon the beach after storms. Both these facts 

 make me regard it as a denizen of the deep sea. No species of 

 Anemone would be less likely to be thrown upon the shore 

 than Troglodytes, which so readily retires under the sand for 

 shelter. 



A. Troglodytes has been supposed to be the young of Actinia 

 crassicornis; that this is not the fact can easily be proved by 

 keeping them. We have had some nearly two years, and they 

 are still Troglodytes.
