THE CAVE-DWELLING ANEMONE.

he describes as of a reddisli-brown or orange hue, with 
white (suctorial) spots, and well-barred tentacles ; the disk 
generally crossed with a white line. The latter has more 
of the ordinary aspect of a troglodytes. 
Sir John Dalyell observed in the latter (which he named 
explorator from the circumstance) the occasional elonga- 
tion of one or two tentacles, which we have seen to be a 
not uncommon phenomenon in this family. A specimen, 
not half an inch in diameter, exhibited two tentacles 
together, each of the length of an inch and three quarters. 
In general, the elongation took place at night. From its 
ordinary length of half an inch, each tentacle gradually 
became two inches long, thickened and distended to 
transparency. “ It is then seen rising from among the 
rest, curving over to the opposite side of the disk, and as if 
searching around.” After a while, it shrank back to its 
former state. 
Both of these (supposed) species were prolific. The 
latter produced sixty young in one night ; which were pure 
white, and large in proportion. Of the former, three indi- 
viduals, in October, produced infusorium-like germs, which 
were ovoid, and yellow-green in hue : some showed a long 
transparent horn in front, visible as the animalcule pur- 
sued a steady course ; behind it was open like a cap. They 
presented much disparity both in form and size. They 
swam actively by means of cilia. These germs continued 
visible throughout October, but, though carefully preserved, 
they led to no ultimate results.* 
Since the earlier pages of this article were issued, I have 
been favoured with an interesting letter from Miss Gloag, 
of Queensferry, Fifeshire, who has long been a successful 
cultivator of Anemones. I regret that limited space forbids 
my giving her communication in extenso : I am compelled
