George Stabler and J. M. Barnes.* — C. H. Waddell publishes an 

 obituary notice (with portrait) of George Stabler (born 1839, died 1910), 

 bryologist, and for many years schoolmaster at Levens, Westmorland. 

 A schoolfellow of the late Richard Spruce, he acquired from him his love 

 of hepatics. With J. M. Barnes and J. A. Martindale he explored 

 carefully much of the Lake District for mosses, ferns, and lichens, and 

 published papers on the Bryophytes in the Naturalist in 1888-1898. In 

 his later years he became totally blind. The following British species 

 were named after him : Plagiochila Stableri, Marsupella Stableri, Antho- 

 ceros Stableri ; also the genus Stableria of Lindberg. 



Waddell also gives a similar account of James Martindale Barnes 

 (born 1814, died 1890), a neighbour of Stabler, and expert collector of 

 ferns and, later, mosses, in Westmorland. His moss-collection is in 

 Kendal Museum. Bryum Barnesii was named after him.

The Roscoff Laboratory.^- — J. Chalon writes an interesting account 

 of the marine station for biology at Roscoff, giving details of the building, 

 the management, the rules, and the facilities for work. A certain number 

 of students can be accommodated within the station itself, and the charge 

 for this is extremely small. All the necessary appliances for work are 

 provided gratuitously. Much good work lias already been carried on 

 at Roscoff, and it is confidently expected that many more students will 

 avail themselves of the exceedingly good conditions to be found there. 

 The author adds a list of the 330 species of marine algae already recorded 

 from the region. 



Greenland Fresh-water Algae.! — F. Borgesen publishes a list of 

 seventy-six species of fresh-water algae collected by the Danish Expedi- 

 tion to the north-east coast of Greenland. The material is rather poor, 

 both as to quantity and quality, and even in those samples which con- 

 tained a great number of species the number of individuals was small. 

 The author attributes this poverty to the faulty manner of collecting, 

 and refrains therefore from making any detailed comparison between the 

 species recorded from East and West Greenland. Among the finds of 

 interest is Spirotsenia, which is new to the country, represented by 

 S. condensata. Another new record for Greenland is Euastrum tetra- 

 lobum Nordst., while Cosmarium spitsbergense Nordst. has hitherto been 

 found only once in Greenland. Nostoc commune appears to be very 

 common, even large specimens being found along the border of lakes or 

 on places which are quite dry in summer. No material of snow-algae 

 was brought home.
