ZOOLOGY AND BOTANY, MICROSCOPY, ETC. uO 



Iceland. It has been compiled from lists published by various authors 

 and from material brought back by the Norwegian Polar Expedition. 

 Darbishire found eight new species in the material brought home by the 

 ' Fram,' the most striking of these being Placodium splendens, somewhat 

 resembling P. elegans, but occasionally forming upright podetia. Fruti- 

 culous lichens grew abundantly, though there are few species ; species of 

 Gyrophora and Parmelia lamia were among the commonest. A series 

 of ecological notes are given of the different lichens, and there is a 

 bibliography of publications on Arctic lichens. Habitat and locality are 

 given with each species. 



Siberian Lichens.* — E. A. Wainio describes the lichens collected by 

 E. Almquist in Northern Siberia, and gives an account of the conditions 

 in which they were found. The country round Pitlekai, where they 

 were collected, is uniform and very bare. On the sand dunes of the 

 sea-shore Cetraria hiascens was occasionally found ; further inland 

 occurred patches of moss and a considerable variety of lichens : Ochro- 

 lechia tartarea, Lecanorse, Lecideee, Pertusarise, Parmelise, Gladonise, etc. 

 Stones the size of one's fist were scattered around, and on these grew 

 another series of crustaceous lichens, Lecideee, etc. On some smaller 

 stones near by, Umbilicaria proboscidea -grew abundantly. Detailed lists 

 of these lichens are given by the author according to habitat, and then 

 a full account of all the species, with diagnosis of new forms. 



Chemistry of Lich.ens.t- An important paper has been issued by 

 Zopf on the chemical products of Peltigera, Solorina, and Nephroma. 

 He finds several new bodies : peltigerin in all the species of Peltigera 

 examined, with the exception of P. canina, P. rufescens, P. spuria, and 

 P. prsetexta. Another new T substance is polydactylin. Zopf deduces 

 from these researches that the genus Peltidea should not be separated 

 from Peltigera, as the chemical products are so akin.
