Here again, the name first proposed by the circumnavigators 

 precedes that in current use. It is a pleasure to reinstate in 

 Australian zoological nomenclature the name of this unfortunate 

 and gallant explorer.

Typically southern is the genus Marsetiiopds, first introduced 

 by Bergh for two subantarctic species taken by the Challenger 

 Expedition, M. pacijica, from Kerguelen, and Af. mtirrayi, from 

 Marion Island. A pair of Antarctic forms, M. conica and M. 

 mollis, were discovered near Cape Adare, Adelie Land, while a 

 fifth, M. antarctica, was dredged by Dr. Charcot off Wandel 

 Island. 



Discussing the distribution of the group in relation to the 

 latter species, Prof. Vayssiere points out that the Australian 

 Lamellaria wilsorii should be here included. In the British 

 Museum, there is a single specimen of L. wilsoni, presented by 

 Mr. J. B. Wilson, and marked "type.' 



I now suggest that a second Austi-alian member is Caledoniella 

 contusi/ormis Basedow.* 



Phytia ornata Ferussac. 

 (Plate 1., tigs.26, 27.) 

 The nomenclature of this species was discussed (an^ea, xxxviii., 

 p. 334) under the heading of Ophicaidehis ornaiiis. 



Its habits are to associate with Bhodostoma, Salinator, and 

 Assemania in the Salicornia-zone, that is, just below high-water 

 level in sheltered estuarine swamps, either in the open or under 

 the shade of the Avicennia-mangrove. At low tide, the Phytia
