 [The species of Musidora are very little understood, and 

 until the genus is carefully investigated it is difficult to 

 say whether we have more than one species in Britain. 

 The specimens here recorded appear all to be forms of one, 

 although they answer to the descriptions of three or four. 

 I have therefore used the earliest specific name.]
