Note. — Throngh inadvertence we have overlooked in this account of the 

 British BulUdce, Mr. Clark's interesting paper in the "Annals of Natural His- 

 tory" for August, 1850, in which there are very full accounts of the animals of 

 Bulla hydatis, Cyliclina cylindracea, and Cylichna iruncata. It is there shown 

 that Cylichta, contrary to the statement put forward at page 507, has a gizzard 

 of testaceous plates, a fact of which we have had further reason to convince our- 

 selves by the examination of specimens kindly forwarded by Mr. Clark. (E. F.)
