Shetland Isles ; iloray Firth ; deep water. 
Looking over the cabinet of Dr. Ilowclen, of ]\Iontrose, 
last winter, my eye fell on this little Coral, which seemed 
new to me. Its owner was so kind as to transfer it to 
my possession, when, on careful examination, it proved 
to be an unrecognised species, with the characters above 
enumerated. It may be distinguished from P. caryophyllus 
by the relative proportion of the height to the diameter, 
and from all other described species by the number of septal 
cycles. 
Dr. Howden dredged the specimen off Ord Head in 
Bressai Sound, Shetland, in thirty or forty fathoms, on a 
bottom of small stones, to one of which it is attached. 
In March of the present year Mr. Gregor sent me, on a 
valve of Lutraria, a specimen, which appears to be of the 
same species, but of younger age. It is not more than 
half the size of the former, but in other particulars agrees 
sufficiently. On my putting it into sea-water on its arrival, 
the pellucid flesh came up and filled the intersepts, giving 
satisfactory evidence of its freshness. Unfortunately it 
had been sent through the post, packed dry ; it was probably 
alive when despatched. The whole corallum in this speci- 
men is of the purest translucent whiteness. It came up 
on a fisherman’s line from the !Moray Firth, in about forty 
fathoms, hard bottom. 
The specific name is from Thule, the ancient designa- 
tion, as presumed, of the Shetland Isles.
