Hepatics of Naples.* — E. Migliorato has compiled a bibliography 

 of the hepatic flora of the Abruzzi and Naples districts, giving the 

 results in three lists : 1. Alphabetical list of authors, with their works. 

 2. Chronological table of the authors. <\. List of the localities, with the 

 names of the authors who studied their hepatic flora. Migliorato has 

 prepared a manuscript alphabetical catalogue of the species contained in 

 these works, and puts it at the disposition of hepaticologists interested 

 in the districts. 



Bryology of Sorrento.f — C Negri gives an account of the mosses 

 of this district, founded on collections made by himself in December 

 and April of 1908 and 1904. He delimits the peninsula topographi- 

 cally, and points out that it includes three groups of mountains, the 

 height and extent of which he describes. The geological formations 

 and the climate are also considered, and the effect of these on the 

 moss-flora. Certain species are enumerated which are found in the 

 highest zones of the mountain regions, and also occur lower down ; and 

 a list is also given of the Mediterranean species of the district. After 

 deducting these two short lists and the cosmopolitan species from the 

 total number of species recorded, it is found that the sub-mountainous 

 region provides a good third of the remainder. As regards the influence 

 of the calcareous stratum on the moss-flora, it is found that of 116 

 species and varieties 21 are exclusively calcareous, 26 prefer it, 29 are 

 indifferent, 19 tolerate it, and 20 are calcifugous. In the general enu- 

 meration of the species the attitude of each as regards this point is 

 stated. A new variety, augustifolium, is described for Milium albicans 

 Simp. 



Sicilian Bryophytes.J — G. Zodda begins a series of contributions to 

 the bryology of Sicily and the adjacent islands. The bryophytes of 

 Messina are excluded, as they have been already treated of in another 

 series of papers by the author, the first of which appeared last year. 

 The material on which the present short list is founded was collected at 

 Riesi, a town in the province of Caltanissetta, in Southern Sicily ; at 

 Linosa in 1884, by Dr. Solla ; and at the same place, in April of last 

 year — on a volcanic rock entirely covered by lichens — by the author 

 himself. The two former collections were found by Dr. Zodda in the 

 herbarium of the Royal Botanic Institute at Messina, and all the species, 

 numbering 15, given in the present paper constitute the first records for 

 their respective localities. Three hepatics were also found in Dr. Solla's 

 collection. They were recorded as growing intermixed with Tortula 

 cesliva on volcanic tufa of Monte Bandiera. 



Brazilian Hepatics.§ — P. Dusen, in his account of the flora of the 

 Serra do Itatiaya in Brazil, gives two lists of hepatics — one consisting of
