extreme diameter, and it tlirew out its tentacle to a dis- 
tance of three inches from tlie margin. Of course all colour 
disappears, and it requires one to Lc looking for the fact 
to observe the transparent membranous nature of the ex- 
tended limb. I tried if its object was seeking for food, by 
dropping a scrap of meat in the way of the tentacle : it was 
seized and carried to the oral disk instantly.” 
The same gentleman in a subsequent letter (dated 7th 
July, 1856) thus continues his observations: — “Another 
specimen of hellis, from Ilfracombe, of a dark self-colour 
(chocolate or umber-brown), is constantly extending the 
tentacles to full four times their length under ordinary cir- 
cumstances ; and on one occasion I have seen a tentacle 
on each side thrown out so loDg as to command fully a circle 
of six inches in diameter. After the extension, I observe that 
the tentacle assumes for several hours a white appearance, 
increasing in intensity towards the extreme tip. This ex- 
treme extensility is interesting, as showing the resources of 
the animal in commanding a larger range for feeding : and 
the modus operandi is no less curious; for, after having 
reached the utmost length, any nearer spot is examined by 
curling the tentacle into a variety of elegant curves and 
rings.” 
]\Ir. E. W. II. Iloldsworth has also favoured me with 
some interesting observations on the same curious habit. 
Kcferring to an example which he had already described to 
me in the case of S. miniata, and which will be detailed in 
its place,^- this excellent observer says : — “ Since my last 
letter I have seen the elongation of one of the tentacles of 
the first row in hellis. The ordinary shape and proportions 
were retained, but the arm was stretclied to more than 
twice its natural length, yet without any appearance of 
unnatimal tension or straining : it was constantly in motion,
