Tliere is some sligbt difference in tbe described characters of 

 the specimens from British America and of those from California. 

 A comparison of the specimens, however, proves the identity of 

 these forms, the differences being merely local and unimportant. 

 Specimens labelled Hypmim vallium have been sent to Bolander 

 and distributed to bryologists long before the preparation of the 

 Musci Exsiccati.
