the name Jungermannia Poeppigiana, and the Synopsis cites 

 it also from Mexico. It has not been reported from Chile 

 since the time of Montagne, and its occurrence there is at least 

 questionable. The status of the var. chilensis will be subse- 

 quently considered. In addition to these species of "Metzgeria" 

 Montague reported both Aneura pinguis and 'A. pinnatifida" 

 from Chile. The latter species, as will be shown later, is variously 

 understood even at the present time. 



In 1872 Angstrom (i, p. 13) listed R. alcicornis and R. prehen- 

 silis (under the generic name Jungennannia) from Port Famine, 

 Straits of Magellan, but nothing further was added to our 

 knowledge of the Chilean species of Riccardia until 1885, when 

 Massalongo (16) published an account of the Hepaticae collected 

 by C. Spegazzini on Tierra del Fuego and some of the neighboring 

 islands. Although a few of the specimens which he recorded 

 came from Argentine territory, they naturally belong in the same 

 floristic region as southern Chile. Massalongo described and 

 figured the following new species ; R. fncgiciisis, R. Spcgasziniayia 

 and R. spimdifera. The first of these has since been repeatedly 

 collected and is one of the most distinctive species of the whole 

 genus ; the other two species are likewise distinctive but are less 

 conspicuous and their distribution is less completely known. 

 Massalongo likewise gave new stations for R. preJiensilis and 

 cited "R. pinnatifida (Schw.)" from Staten Island (east of Tierra 

 del Fuego). Four years later Bescherelle and Massalongo 

 (2) published an account of the Hepaticae collected by Savatier 

 and other members of the French Mission to Cape Horn. The 

 following species of Riccardia were included : R. criocaula var. 

 chilensis, R. fucgicnsis, R. pinguis, R. prchcnsilis, R. Spcgac- 

 ziniana and R. spinitlifera. The first of these, which is cited from 

 several localities, is compared with R. prchcnsilis and with the 

 typical form of 7?. criocaula from New Zealand. 



In the following year, 1890, Schiffner (19) gave a full report on 

 the Hepaticae collected in the vicinity of the Straits of Magellan 

 by Dr. Naumann, botanist of the "Gazelle" Expedition. The 

 following eight species among those he recorded would now be 

 included under Riccardia: Aneura calz'a. A. uiultifida, A. pinnatifida, 

 A. iimhrosa, Pseudoncura crispa, P. fucgicnsis, P. prchcnsilis and 

 Spinclla niagcUanica (the last being based on Massalongo's Ric-
