ferous Hedwigice and Leucodon sciuroides, which produces flagella 

 of exactly the same kind as those of H. (Braunid) sciuroides. In 

 Cryphea there are several species which closely resemble H. 

 ciliata and H. imberbis, having their fruit terminal on their 

 branches, and immersed in a similar manner. There is also a 

 great resemblance between the more branched Hedwigus and 

 Antitrichia curtipendula, Brid., which also produces the same kind 

 of flagella, and is in reality itself only a Leucodon with a more 

 completely developed peristome, and improperly separated from 

 that genus. 



Since the foregoing description of this moss was written, there 

 has appeared, in the Transactions of the American Philosophical 

 Society, Mr. Lesquereux' s description of Braunia Californica, which, 

 in so far as can be generally gathered from the description, would 

 appear to indicate the same species. On consideration, however, 

 as there are some discrepancies, it has been thought best to let the 

 description of H. pilifera stand, and to point out the differences 

 which exist between Dr. Ly all's specimens and Mr. Lesquereux' s 

 description. They are, in our specimens, 'the stems not " vel 

 simplicibus vel irregulariter innovando ramosis," nor "apice 

 incrassatis duris;" the perichsetial leaves not " brevioribus," but 

 elongated, and the capsule plicate — in fact it is just the cap- 

 sule of H. imberbis on an elongated pedicel. Mr. Lesquereux 

 says that his species has a capsule "exactly top-shaped" when 

 deoperculate, but nothing about the plication so evident in our 

 specimens.

Very different in external appearance from the usual European 

 states ; but there seems to be no sufficient distinction between 

 these specimens and the form which has a more slender habit 

 and elongate capsules, enumerated by Schimper as var. /3. His- 

 panica. Some of the specimens are very slender.
