rated from Nardia (p. 113) and our species become 31. spha- 

 celate* (Gies.) Dum. (p. 114), M. emarginata (Ehrh.) Dum. 

 (p. 114) and M. adusla (Nees) (p. 114). Nardia, however, 

 receives a considerable accession from Jungermania as fol- 

 lows : N. hyalina (Lyell) Carr. (p. 102), N. crenulata (Sm.) 

 Lindb. 23 (p. 101), N. creuuliformis (Aust.) Lindb. (p. 101). 

 -.V. biformis (Aust.) Lindb. (p. 102), and N. fossombronioidcs 

 (Aust.) Lindb. (p. 101) the last forming a distinct subgenus. 

 Cesia (p. 115) is preoccupied as Cassia (R. Br. t8io) in 

 the Liliaceae ; hence our species must be referred to Gym- 

 nomitrium (Nees, 1833) anc * becomes G . concinnatum (Lightf.)

Steetzia (p. 57) becomes Pallavicinia as noted above, and 

 our species is P. Lyellii (Hook.) S. Gray. 



The species which since the days of Schweinitz, the father 

 of American hepaticology, has been confused under the name 

 of A. palmata (p. 54), is a very distinct species which has 

 been described as A. latifrons Lindb. 



Lunularia cruciata (p. 43) was described by Micheli long 

 before Linnaeus called it Marchantia cruciata ; hence it must 

 be called Lunularia vulgaris Mich. 25 



Duvalia (p. 35) and Grimaldia (p. 35) form one genus as 

 early held by Bischoff 26 and later insisted upon by Lind- 

 bergh, who, however, reduces all to the genus Duvalia 



(Nees, 1817). As there is an earlier Duvalia (Haworth, 181 2) 

 the species must be placed in Grimaldia (Raddi, 1818). Our 



species of Duvalia thus becomes Grimaldia rufestris Lindenb. 

 Riccia bilurca (p. 23) is omitted, there being no probabil- 

 ity that it is a member of our flora. 



Sphaerocarpus Micheli (p. 30) has a much earlier name. 



S\ terrestris Mich.," which must take its place in our list. 

 Four species are known only from their original descriptions, 



no specimens, so far as we are aware, existing in any American 

 collection; these are (1) Frullania Pennsylvania Stepham, 

 (2) Jungermania Gillmani Aust., (3) 7- Wattiana Aust. and 

 (4) Cefhalozia flenicefs (Aust.) Und. These should be spe- 

 cially sought by collectors in the higher latitudes. Two species 

 must be added to our list, viz. : (1) Frullania dtlatataO,.) 

 Nees, and (2) Pellia endivice folia (Dicks.) Dum., which ha
