Ac. LONDON: PRINTED BY ORDER OF THE TRUSTEES 1857. PRINTED BY TAYLOR AND FRANCIS, RED LION COURT, FLEET STREET. PREFACE The object of the present Work is to explain the manner in which the Collection of Mollusca and their shells is arranged in the British Museum, and especially to give a short account of the chief characters, derived from the animals, by which they are dis- tributed, and which it is impossible to exhibit in the Collection. The figures referred to after the names of the species, under the genera, are those given in " The Figures of Molluscous Animals, for the Use of Students, by Maria Emma Gray, 3 vols. 8vo, 1850 to 1854 ;" or when the species has been figured since the appear- ance of that work, in the original authority quoted. The concluding Part is in hand, and it is hoped will shortly appear. JOHN EDWARD GRAY. Dec. 10, 1856. ERRATA AND CORRIGENDA. Page 43. Verenad.e.—This family is to be erased, as the animal is like Tricho- tropis. I was misled by the incorrectness of the description and figure. Page 63. Tylodinad^e.— This family is to be removed to PleurobrancMata at page 203 ; a specimen of the animal and shell having since come into my possession. Pages 135 & 167. For Cirrhobranchia read Cirrobranchia. Page 141. Erase Chrysostoma, which is inserted in its correct place as part of Livona at page 156. Pa^e 159. For Stomatia read Stomas. TABLE OF CONTENTS.
