XV. — On a new British Species of Spatangnsv 
By the Rev. John Fleming, 
Minister of Flisk. 
{Read 91st March 1824.) 
The portion of the animal which I am now about i& 
describe, and which appears to constitute an addition ta 
the British Fauna, has been in my possession nearly four- 
teen years. I formerly alluded to it in the " Contributions 
to the British Fauna,"" inserted in the second volume of the 
Memoirs of this Society, p. 247, as a species nearly allied 
to the common sort found on all parts of the coast. In- 
deed, I entertained some suspicions that it might prove 
only a variety ; but having since examined many examples 
of the common species, and never perceived any approach^ 
by gradation to the characters which it exhibits, I can now 
with some degree of confidence announce it as distinct. 
Spatangus ovatus. Groove between the mouth and ver= 
tex obsolete. Leske, ap. Klein Ech. p. 252, tab. xlix. f. 12. 
13. — Only one specimen occurred in a fishing-boat from 
the deep sea cod-fishery, Zetland, 1809.-- See Plate VI,,
