Eighteen or twenty individuals were found together under a 
stone among the rocks at Whitley, feeding upon Laomedea gela- 
tinosa.—A. H. 
We have not met with the Holidia Cuviert of Dr. Johnston, 
found by him in Berwick Bay, though it is most likely an inha- 
bitant of the Northumberland coast. 
A small Holis from Whitley rocks was described in the Annals 
of Natural History, under the name of Holis minuta. The de- 
scription was taken from an imperfect specimen, and as it has 
never occurred again, and there is a degree of uncertainty at- 
tending it, we have left it out of the present Catalogue.
