APPENDIX 4.

ACCOUNT OF THE POLYZOA AND SERTULARIAN ZOOPHYTES, COLLECTED IN THE VOYAGE
OF H.M.S.  RATTLESNAKE, ON THE COASTS OF AUSTRALIA AND THE LOUISIADE
ARCHIPELAGO, ETC.  BY GEORGE BUSK, ESQUIRE F.R.S.

This collection includes about eighty-five species, distributed in twenty-nine genera, and may perhaps be regarded as the largest and most interesting of the kind ever brought to this country.

When it is stated that seventy-eight of the species are new or undescribed, the number will appear extraordinarily great, but when the comparatively neglected state of exotic Zoophytology is considered the wonder will be much diminished, and still further, as it may safely be assumed, that many of the species here given as new have been previously noticed, though so insufficiently described, as in the absence of figures not to admit of correct identification.

Making, however, a considerable deduction on this account, the remainder will still stamp the present collection with extreme value.  As an instance, may be cited the genus Catenicella, of which this collection affords about fifteen species, and of which certainly not more than three have been previously noticed in any way, and of these no sufficient descriptions or figures are extant by which even that small number could be identified.  The explanation of this is perhaps to be sought in the circumstance that the species of Catenicella are deepsea forms, and only to be obtained by dredging in deep water—­very few being apparently found on the shores.
