IV. EXCLUDED SPECIES 



In the Introduction attention is called to several species of Ric- 

 cardia which have been reported from Chile but about which there 

 is more or less uncertainty. For the sake of convenience these 

 species are again enumerated here, five being listed under 

 the generic name Aneura to avoid the publication of new 

 combinations. 



1. RiccARDiA ERiocAULA (Hook.) Bcsch. & Massal. 



Puerto Bueno, Duscn (28, p. 18, as Aneura eriocaula) ; Huafo 

 Island and Puerto Gomez, Tierra del Fuego, Skottshcrg (28, p. 7, 

 as A. eriocaula) . 



The specimens cited under the var. chilensis have been included 

 under R. prehensilis, and it is probable that these other records 

 were based on specimens of the same species. 



2. AxEURA FRAGiLis Stcph. Bihaug K. Svenska Vet.-Akad. 

 Handl. 26^ (No. 17) : 8. 1901. Nonien nudum. 



Desolation Island and Rio Azopardo, Tierra del Fuego, Dusen. 



According to a letter received from Professor Chodat of the 

 University of Geneva, there are no specimens under this name in 

 Stephani's collection. 



3. Aneura fucoides (Sw.) Steph. 



Straits of Magellan, reported by Montague (17, p. 214, as 

 Metsgeria fucoides). 



According to Stephani (27, p. 680) this species is known from 

 several of the West Indian islands, from Costa Rica and from 

 Brazil. It is related to R. Thaxteri but is larger, and the wings 

 of the ultimate branches are broader. 



4. RiccARDiA MULTiFiDA (L.) S. F. Gray. 



Hermite Islands, Hooker (14, p. 479, as Jungermannia multi- 

 fida ; 34, p. 444, under the same name, some of the specimens being 

 referred to a var. submcrsa) ; Tuesday Bay, Naumann (19, p. 42, 

 as Aneura multifida) ; Ushuaia, Tierra del Fuego, Skottsberg 

 (31, p. 2, as A. multifida). Reported also from the Falkland 

 Islands (34, p. 444; 31, p. 2).
