never found it associated Avitli tlie A. mesemhr^anthemiim, 
and rarely more than one or two in tlie same locality 
(though explored ^by me in Cornwall), with one exception. 
On the under surface of some very large stones used for 
making a pier near the north-western extremity of the 
town of St. Ives, I found several colonies of the in- 
teresting creatures in full health, enjoying the blessings of 
freedom in a nook not often disturbed by anything but 
the rough and boisterous waves from the North Channel. 
About twenty feet from this spot, and nearer high-water 
mark, tlie under surfaces of the stones forming a portion 
of this abortive construction were covered with old and 
young members of the beautiful varieties of the A. mesem- 
bryanthemum, dark bottle-green with yellow dots, dark 
green with yellow stripes, claret with yellow spots, yel- 
lowish green, light ochre, amber, scarlet, &c. The blue 
beaded rim and blue fillet at base were displayed by each 
member of this group. A specimen of the A. cMococca, 
which I had in confinement for more than twelve months 
in my experimental jar, furnished me with a batch of young 
ones, — all were true to colour and markings.” This, how- 
ever, can by no means outweigh the positive evidence on 
the other side furnished by Sir J. Daly ell. 
Nor can the A. margaritifera of Templeton be allowed 
any higher rank. The flattened, rigid, corrugated con- 
dition on which he relied for a specific character, I have 
not imfrequently seen in individuals, which, in the course 
of an hour or two, were swollen out to the softness and 
plumpness normal to the species. ]\Ir. Cocks comes to 
my aid here with an interesting narrative of two specimens 
which he found in a condition exactly corresponding to 
Mr. Templeton’s description of margaritifera. He was at 
once convinced that sickness was the cause of their pecu- 
liar flatness and attenuation, and the shrivelled tesselated
