In sculpture this little species resembles a Lovenella, especially L. austrina, 

 Heclley,* from the opposite shores of Antarctica. It is only about a quarter of the 

 size, however, of this shell, while the apex is heterostrophe, the peristome continuous. 

 FISCHER (Man. de Conch., p. 172, 1887) gives a list of Magellanic Mollusca, and 

 includes a " Matliildn. magellanica." This is evidently a " noraen nuclum." No 

 description can be found, and the name rests on no authority. The remarks of 

 M. DE BOURY f will probably, in connection with this, be found of interest, 

 contending with cold.)
