The supplementary plates and descriptions of Cyclostoma, pl. 31a, 314, and pages 157*, 168*, should be placed following pl. 31 and page 156 in Vol. L., if that volume is still unbound. [If not, at the end of Vol. IL.

As the plan formerly recommended, of binding the plates separately from the text, does not seem to succeed, perhaps it will be better to place the plates after the text of each genus. For the convenience, however, of those who wish it, a second copy of the Title and Contents is given.

NOTICE.

in publishing the completion of the Second Volume, the Editor again thanks his friends for their support, and again apologizes for all delays. Any considerable increase in the former will be followed by a de- crease in the latter.

Many of the Subscribers are already aware that the Editor’s father, Mr. G. B. Sowerby, F.L.S., to whom they are indebted for several Monographs, has been removed by death, after a life devoted to Science. His family, his acquaintances, his commercial patrons, and his fellow labourers in Natural History, will ever remember him with affection and honour, as a husband, a father, a friend, a man of inte- erity, and a useful contributor to knowledge.

The business at 70, Great Iussell Street, is continued by a part of

the family.
