Owing to unavoidable circumstances, the paper of Dr. Ginsburg on the KABBALAH, for which the publication of this Volume has been delayed for some months past, is not yet completed. It is therefore deemed desirable to issue the present Volume without it, and the paper will appear in the succeeding Volume, which it is hoped may be ready about July or August.

N.B.-The paper by Mr. Williams on a new species of Chatopterus has meanwhile appeared in the Linnæan Transactions, the Annelid being named by Dr. Baird, Chatopterus insignis.
