authors of this paper introduce a third sub-genus, Flabellarieae, into 

 which fli'-;. gather all the tmcalcified genera which had formerly been 

 included in [Jdoteae, while in [Jdoteae tiny place calcined genera only. 

 These sub-families are regarded by them as fundamentally distinct. A 

 synopsiH of genera is followed by a full treatment of each genus, with 

 keys to the species, list of synonymy, geographical distribution, and 

 critical remarks. The species of Godium found by the 'Siboga' are 

 merely enumerated, together with a list of their localities, and two new 

 species are described. Original types of the species, both old and new, 

 are figured in twenty-two plates. 



Fresh-water Algae of Greenland.* — H. Bachmann publishes some 

 information on the fresh-water algae of Greenland, the result of collec- 

 tions made by himself and others. He finds that the Flagellatae are 

 much commoner and more widely distributed than has been supposed, 

 and he adds new records. Of the Peridinieae, Geratium is entirely absent. 

 The typical plankton-diatoms (Aster ionella, Fragilaria, Cyclotella, Rhizo- 

 solenia) are absent, and other diatoms are sparsely represented. Nostoc 

 and Anabsena are common, and seven genera of the Schizophyceae are 

 recorded there for the first time. Desmids appear in every fresh-water 

 pool, and the author adds to the list of records. Chlorophyceae are not 

 large in quantity, but they are widely distributed. The predominant 

 developments are : November to January, Diatoms and Peridinieae : May 

 to July, Dinobryoii and second Diatom-development : July to September, 

 Desmids. A comparison with other regions shows a similarity to Scot- 

 land and Switzerland. 



Algae of Andritz.f — F. Wonisch writes a short account of the flora 

 of the " Quellengebiet " of Andritz, which includes thirty-five species. 

 The commonest of these were Conferva bombycina and Closterium maci- 

 lentum, the latter being a new record for Styria. 



Fresh-water Algae from Macedonia.} — S. Petkoff enumerates some 

 algae collected by him in the lakes, ponds, and marshes in different parts 

 of Macedonia. Twenty-five species and forms are recorded as new to 

 science. Information is also given with regard to the Thallophytes, 

 Muscineae, and Vascular Cryptogams. 



M. A. Gomont.§ — E. Bornet writes an interesting account of the late 

 Maurice Augustin Gomont. He was born at Rouen on May 11, 1839, 

 the descendant of an ancient Norman family. He had a brilliant career 

 at the College Bonaparte, where he was a fellow T -student of Sully, Prud- 

 homme. Carnot, and other distinguished men. In 1858 Gomont entered 

 the school of forestry at Nancy, and was subsequently appointed to be 

 Garde-general of the forests round Rouen. However, the administrative 

 duties of his post becoming irksome to him, he gave up the appoint- 

 ment. He then gave himself to a serious study of painting, a taste he 

 bad inherited from his mother, and was successful enough to win several
