TJie Genus Riccardia in Chile. 99 



cardia spinulifera). Of these species Ancura calva, A. umhrosa 

 and Pseitdoncura crispa were proposed as new. In connection 

 with P. prclicnsilis Schiffner expressed the opinion that this species 

 and P. criocaula were scarcely distinct, and he stated further 

 that some of the specimens referred by Bescherelle and Massalongo 

 to the var. chile iisis were indistinguishable from some of Spegaz- 

 zini's specimens of P. prehensilis. 



In 1893 Stephani (26, pp. 21, 26) published two new species 

 of Riccardia from the Straits of Magellan under the names Aneura 

 granulata and A. Savatieri. The first of these (as appears from 

 a later publication) was based (at least in part) on a Staten Island 

 specimen collected by Spegazzini ; the second, on a specimen 

 collected by Savatier and referred by Bescherelle and Massalongo 

 to Riccardia preJiensilis. Stephani at first implied that Aneura 

 prehensilis was restricted to New Zealand ; later in the same year, 

 however (26, pp. 137, 138), he cited it from the Straits of 

 Magellan only. 



Meanwhile, in 1892, the writer (8) had cited Ancura multifida 

 doubtfully and A. fuegiensis definitely from southern Patagonia, 

 basing these records on specimens collected by the "Albatross" 

 Expedition. Six years later (9), in his report on the Hepaticae 

 collected by J. B. Hatcher in the same region, five species of Ric- 

 cardia were included, as follows: Aneura calva, A. crispa, A. 

 fuegiensis, A. prehensilis and A. Spegazziniana. The anatomical 

 structure of A. prehensilis was described in some detail and among 

 its synonyms Stephani's A. Savatieri was included. It will be 

 shown in the present paper that this reduction to synonymy was 

 unwarranted, and that two of the other determinations made 

 by the writer need to be revised. The report on the Hatcher col- 

 lection was republished in 1903 (10). 



In 1899 Stephani (27) published a monograph of the genus 

 Aneura and described the following new species from Chilean 

 territory: A. autoica, A. conimitra, A. corralensis, A. florihiinda, 

 A. Negeri, A. pallidevircns, A. spcctahilis and A. tcnax. In 

 the same work he accepted the reduction of his A. Savatieri to 

 synonymy under A. prehensilis and cited the following nine species 

 of the genus from Chile, in addition to his eight new species, thus 

 making seventeen in all: A. alcicornis, A. calva, A. crispa (under 

 which A. umhrosa is included as a synonym), A. fuegiensis, A.
