THE DAHLIA WARTLET.

erassicornis, the tentacles much longer and more slender, 
the warts fewer and of a purplish hue. He has favoured 
me with a spirited drawing of it, but I cannot satisfy 
myself that it is anything more than T. erassicornis. 
Tealia tuberculata (Cocks). 
In the Keport of the Cornwall Polytechnic Society for 
1851, Mr. W. P. Cocks has described and figured a species, 
which he names Actinia tuberculata. “ Body globular, light- 
brown, densely covered with large greyish-white tubercles, 
the apex of each tubercle depressed; disk white; mouth 
large; lips thick, con-ugated, and everted; tentacula nume- 
rous, large, obtuse, some bifurcated, others trifurcated. 
Diameter three and a half inches when contracted.” By 
private communication I learn farther particulars. It was 
obtained thirteen miles south-west from Falmouth, attached 
to a valve of Pecten maximus ; it lived with ^Ir. Cocks for 
some months. “ Bulky, rather loose in texture, when fully 
expanded covering the bottom of a large pan, — it had the 
appearance of a mammoth hellis. It appeared to be ex- 
tremely irritable, and upon the slightest provocation would 
throw off from its body a large quantity of thick glaire, 
which, if allowed to remain, produced a disagi'eeable smell. 
When contracted it had the appearance of a half-boiled 
sago pudding.” 
I ventured to suggest that it might have been a great 
colourless deep-water specimen of erassicornis; but ]\Ir. 
Cocks repudiates the identification, while he admits the 
relationship. The tendency of the tentacles to a monstrous 
fission seems to me its most marked peculiarity. It may 
be distinct.
