We have not met with the Eolidia Guvieri of Dr. Johnston, 

 found by him in Berwick Bay, though it is most likely an inha- 

 bitant of the Northumberland coast. 



A small Eolis from Whitley rocks was described in the Annals 

 of Natural History, under the name of Eolis 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.
