In Muséum d'Histoire naturelle, Paris, are to be found the type-spe- 

 cimens of species described by Lamarck, Poirkt, Desvaux, Fournier and some of 

 those described by Fée. 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 Fée in his 5.^ — 10. mémoire sur la famille des fougères 

 were not found there, and I dare not know, where they are. 



Prince Roland 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 Växter och A re h ego n later« 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 Willdenow, Link, Klotzsch, Mettenius, Kuhn and Hieronymus. 



The University Museum of Prague, the genera Nephrodium and Lastrea 

 from Presl's herbarium, which besides the original specimens of species described 

 by Presl also contains several authentical specimens of species described by 

 Kunze. 



The University Museum, Vienna, some original [specimens of species 

 described by Christ. 



Royal Botanic Gardens, Kew, all type-specimens of species described by 

 Hooker and Baker, besides several authentical specimens of species described by 

 SoDiRo 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. Christ, Basle, and Dr. E. Rosenstock, 

 Gotha, the type-specimens of the species described by these two celebrated pterido- 

 logists. From Dr. Christ I have received also several authentical specimens of 

 species described by Sodiro. 



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.
