.hiina m New Granada. Both plants have the same cristate internal 

 lamellse al the base of the peristome teeth. Such variations of structure 

 as occur are of less than varietal importance. Eampe's name antedates 

 Mitten's by Beven pears, [ncluded in the synonymy is Schistophyllum 

 Orrii, a Dublin alien described by S. 0. Lindberg twenty years ago. 



Adalbert Geheeb.* — T. Herzog writes sonic reminiscences of the 

 bryologist A. Geheeb (b. L842; d. 1909), for many years a chemist al 

 C,' MS;l . |l,. made innumerable visits to the Rhongebirge, and devoted 

 much time to the investigation of its muss-flora. He also made his mark 

 as an authority on exotic mosses, working out Puiggari's Brazilian collec- 

 tion, as well as collections of Australian and Papuan mosses belonging to 

 Melbourne herbarium. One of his best known publications is his Xeue 

 Beitrage zur Mossflora von Neu-Guinea (1881) and 1898), illustrated 

 with fine plates. His Bryologia Atlantica, begun in 1891, has recently 

 been completed and published by T. Herzog. 



Nils Conrad Kindberg.f— This bryologist is the subject of a brief 

 obituary notice. He died in August 1910, at Upsala, being 78 years of 

 age. By profession a lecturer at Linkoping, he devoted the last thirty 

 years of his life to North American bryology. His moss-herbarium, 

 'containing 4000 species, is offered for sale.

Locomotion in Surirella.J — T. C. Palmer writes an able account 

 of the apparatus of locomotion in Surirella, founded on bis own careful 

 observations. He criticizes the views and arguments of Lauterborn, and 

 goes minutely into the differences between that author's results and his 

 own. Palmer's material was taken from a pool of pure water, on the 

 bottom of which are patches of diatoms, including Navicula iridis Ehr., 

 N. dactylus, N. socialis, and Surirella elegans. A layer of these diatoms 

 kept in good condition for weeks at a time in a bottle, and was available 

 for stmfy. A number of significant observations were made on all the 

 species, but the apparently conclusive facts have to do with Surirdla. 

 The results are summed up by the author as follows :— 1. Butsehli 

 granules, or bodies of the same deportment in life, circulate into the keel 

 and run along its base. 2. Staining the living diatom with Bismarck 

 brown and tannic acid fails to indicate coleoderm within the keel, though 

 revealing it in the same preparation upon Eunotia and Pinnularia. 

 ?>. After rapid killing and fixing, both eosin and iron-alum-hasmatoxylin 

 show the keel-canal more or less full of a substance continuous with the 

 protoplasm of the rib-canals, and staining like it, and showing the same 

 granular constitution. The author considers it demonstrated, therefore, 

 that the protoplasm of Surirella extends through the ribs into the keels, 

 wherein it runs from end to end of the diatom and occupies most of the
