AURICULID^E. 51 



Menke adopted the genus Pedipes in Lamarck's family Pli- 

 cacea. Reeve proposes to reunite it with Auricula. 



Till the year 1832 all knowledge of the animal was exclu- 

 sively drawn from Adanson, and then Lowe was the first who 

 confirmed that author's observations. He found the typical 

 species abundantly on the north coast of Madeira under stones, 

 together with two species of Melampus, and demonstrated by a 

 series of experiments, that the animals like to live in salt water, 

 and are able to remain above the surface of the water. Yet 

 he does not hesitate to regard them as true Pectinibranchiata. 

 The other species, which by analogy are now considered as 

 belonging to Pedipes, have not been observed, or at least not 

 described, hi the living state.
