478 SUMMARY OF CURRENT RESEARCHES RELATING TO 



the appearance of a primitive ancestral Funaria, and suggests that in 

 the Pentland Hills plant we have a reversion towards the primitive 

 organs of the ancestral plant. 



Photomicrography of Mosses.* — W. B. Davis describes a method 

 of making photomicrographs of mosses and hepatics — an easy thing to 

 do in most cases, the Microscope preparations being as a rule fairly 

 transparent. Quite simple apparatus will with care afford good results. 



Fauna of Mosses.f — F. Richters has been studying the fauna 

 of moss-tufts, and gives an account of the Invertebrata found in a 

 collection of mosses brought back by the German Antarctic Expedition 

 from the Island of Ascension, and also in mosses from the Comoro 

 Islands, from Sumatra and Java. 



Moss Galls. $ — M. Spindler describes the character of some Nema- 

 tode-galls on Webera nutans, apparently not noticed before on this 

 species, and certainly not mentioned in V. Schiffner's paper on moss- 

 galls in the same journal three years ago. Spindler believes that in 

 W. nutans, as in other species, the galls are produced by Tylenchus 

 Davainii Bast., an Anguinule or Nematode-worm. 



Bryological Notes. § — V. Schiffner continues his bryological notes. 

 53. On Riccardia sinuata, three different forms of which were gathered 

 by E. Stolle in Saxony last summer. One of these is described as a 

 new var. subincurvata. 54. On Riccardia major. Schiffner objects to 

 C. Midler's making this species a mere variety, and maintains that it 

 cannot be regarded as a synonym of R. sinuata, which is always 

 aquatic or subaquatic, and has a greater number of cell-layers in the 

 transverse section of its stem. 55. Occurrence of Neesiella carnica in 

 lower Austria and Hungary. The plant was known previously only 

 from the Italian Carnic Alps ; but now it has been recorded from 

 several stations between the Eastern Alps and the Hohe Tatra. 56. On 

 Lophozia acutiloba, recorded from two stations near Salzburg, from one 

 of which came the original specimen of Jungermannia inflata var. 

 nigricans Nees, the description of which corresponds closely with that 

 of Lophozia acutiloba var. heterostipoides. 57. On an interesting form 

 of Brachythecium campestre. It is polygamous. He also publishes || an 

 account of two critical hepatics of the European flora, Aplozia 

 Schiffneri and Lophozia acutiloba, discussing their morphology and 

 relationships in considerable detail, and defining their distribution. 

 He gives careful figures of habit and structure. 



European Species of Drepanocladus.lf — 0. Roth publishes a review 

 of the European species of Dr&panocladus, embodying the conclusions 

 to which he has come after studying a rich series of specimens from 

 swamps in Livland sent to him by W. von Bock. He insists upon the
