APPENDIX 5.

ON THE MOLLUSCA COLLECTED BY MR. MACGILLIVRAY DURING THE VOYAGE OF THE
RATTLESNAKE, BY PROFESSOR EDWARD FORBES, F.R.S.

1. ON THE BATHYMETRICAL DISTRIBUTION OF MARINE TESTACEA ON THE EASTERN
COAST OF AUSTRALIA.

As in every instance the exact locality, depth and character of habitat
of species of Mollusc taken were carefully noted of at the time of
capture, much more valuable information elucidating the distribution of
shellfish in the Australian seas has been collected during this
expedition than was ever before obtained. Whilst new species are usually
sought after by collectors with eagerness, the habits and range of the
commoner or less conspicuous forms are passed over without observation.*
Hence every note on the habitat and mode of life of marine creatures from
the southern hemisphere becomes of no small value. Indeed, there is no
information more desirable at this time for the illustration of
geological phenomena, than such as may throw light on the distribution in
range and depth of the creatures inhabiting the sea of the Tropics, and
those living around the coasts of Australia and New Zealand. The
following notes will serve to record the more prominent facts bearing
upon the Bathymetrical distribution of the Testacea collected on the
northern coast of Australia, at Port Essington, and on the eastern coast
from Cape York to Bass Strait, including the northern ports of Van
Diemen's Land.

(*Footnote. An extensive collection of landshells was made at Madeira.
They proved on examination to be all known species, including several of
the rarer forms, and not a few of those discovered by the Reverend Mr.
Lowe. They were compared with Madeiran specimens by Mr. Vernon Wollaston.
When the Rattlesnake touched at the Azores on the return voyage, a few
landshells were collected at Fayal
