In Muséum d'Histoire naturelle, Paris, are to be found the type-spe- 
cimens of species described by Lamarck, PornET, DESVAUX, FouRNIER and some of 
those described by FÉr. I paid a visit to the museum in the summer 1909 and 
found the majority of the type-specimens mentioned. The original specimens of 
the species described by FÉr in his 5.—10. mémoire sur la famille des fougéres 
were not found there, and I dare not know, where they are. 
Prince RoLtanp BONAPARTE’s comprehensive herbarium, no doubt the largest 
private collection in existence, contains numerous authentic specimens; especially 
are Spruce’s South-American collections richly represented. The type-specimens 
of the species recently described by Dr. Rosenstock from Spruce’s collections are 
in Herb. Bonaparte, and I have had them for study. 
In February 1909 I was at Stockholm, where I found in »Riksmuseets 
Afdelning for Fossila Vaxter och Archegoniater« the original specimens 
of species described by O. Swartz a hundred years ago'). Authentical specimens 
of not a few of the Swartzian species are to be found in the Botanical Museum of 
Copenhagen. 
On loan I have received from 
Kgl. Botanisches Museum, Dahlem bei Berlin, the type-specimens of 
species described by WiILLDENOw, Link, KrorzscH, METTENIUS, KunN and HIERONYMUS. 
The University Museum of Prague, the genera Nephrodium and Lastrea 
from PnEsr's herbarium, which besides the original specimens of species described 
by Presi also contains several authentical specimens of species deseribed by 
KUNZE. 
The University Museum, Vienna, some original 'specimens of species 
described by Curist. 
Royal Botanic Gardens, Kew, all type-specimens of species described by 
HookER and Baker, besides several authentical specimens of species described by 
Soprro and JENMAN. 
Botanisk Museum, Copenhagen, LiEBMANN's Mexican collections. 
New York Botanical Garden, some original specimens of JENMAN's her- 
barium, kindly sent to me by Miss MARGARET SLOSSON. 
U. S. National Museum, Washington, type-specimens of species de- 
scribed by BRACKENRIDGE, DAVENPORT, DONNELL SMITH, MAXON and JENMAN. 
Finally I have received from Dr. H. Curist, Basle, and Dr. E. RosENSTOCK, 
Gotha, the type-specimens of the species described by these two celebrated pterido- 
logists. From Dr. Curist I have received also several authentical specimens of 
species described by Soprro. 
As it will be seen from the enumeration above there remain only some few 
type-specimens, which I have not seen. The “species”, which I have not seen, are 
enumerated partly under each subgenus, partly at the end of the work.
