Extract

Muscles.—As the number and position of these organs differ materially in the two great divisions into which the Brachiopoda have been separated, and to some extent, also, in the different genera of which each division is composed, it may be desirable to treat this subject under two different heads.

page 202 note 1 The reader is referred to an important paper upon this subject by Prof. Edward Suess, über die Wohnsitze der Brachiopoden (Aus dem xxxvii. und xxxix. Bande, Wien, 1859, 1860, Akademie der Wissenschaflen besonders abgedruckt).

page 203 note 1 Mr. Vélain informs me, that the Brachiopods he forwarded to me (a species of Kraussina) are found in great abundance on the shore, in the interior crater of the island of St. Paul. During the ordinary low tides they are scarcely covered by water, and are alternately covered and left bare at the ebb and flow of the tide, but twice a month, during the high tides, they are left completely dry. They occur only in an area of a few yards, and consequently at a very shallow depth, doubtless because they find there those undisturbed conditions to which they are accustomed in other localities.

Suess and Count Marschall was also published in Vienna in the same year, 1856.
