THE DAHLIA WARTLET. 217 



crassicornis, 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. crassicornis. 



TEALIA TUBERCtTLATA (CockB). 



In the Report 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, corrugated, and everted ; tentacula nume- 

 rous, large, obtuse, some bifurcated, others trifurcated. 

 Diameter three and a half inches when contracted." By 

 private communication I learn further particulars. It was 

 obtained thirteen miles south-west from Falmouth, attached 

 to a valve of Pecten maximus ; it lived with Mr. 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 bellis. 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 disagreeable 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 crassicornis; but Mr. 

 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.
