C. B. Yule^ R.N.^ and Lieut. J. Dayman^ B.N.^ I 

 beg* to express my thanks for the Hberal manner in 

 which they carried out their Lordships' intentions. 



To the other g-entlemen A\ho have contributed 

 Appendices to this work — Georg'e Busk^ Esq. F.R.S., 

 Dr. E. G. Latham^ Prof. Edward Forbes^ F.B.S.^ 

 and Adam AVhite^ Esq.^, F.L.S. — I have also to 

 offer my best thanks. It also affords me great 

 pleasure to record my obligations to T. Huxley^ 

 Esq. R.N.^ F.E.S.; late Assistant-Surg-eon of the 

 Rattlesnake^ for the handsome manner in which he 

 allowed me to select from his collection of drawing's 

 those which now appear as illustrations \ and I may 

 express the hope^ which in common with many 

 others I entertain^ that the whole of his researches 

 in marine zoology may speedily be laid before the 

 scientific world. My own collections in Natural 

 Plistor}' have been submitted to the examination of 

 various eminent naturalists. Man}* of the novelties 

 have already been described^ and the remainder will 

 appear fi'om time to time.
