The type of Plagiochila abdita is not to be found at present in 

 the Sullivant Herbarium, but there is a drawing of the species 

 there, which agrees very closely with the Lapotaia specimens and 

 also with the published descriptions and figures* of Leioscyphus 

 pallens. The two genera, Mylia and Leioscyphus (or Leptoscyphus), 

 are both given places by Schiffnerf in his recent treatment of the 

 genera of Hepaticae. He recognizes, however, that they are very 

 close to each other and points out only two, purely vegetative,

 first distinction, however, does not hold, as there are acknowledged 

 species of Leioscyphus (e. g. f L. chiloscyphoideus) with alternate 

 leaves ; and the second distinction seems hardly sufficient to sep- 

 arate the genera.
