partly from Kimli on the east coast part I y from anotlier locality 

 unknowii to me, ^) and tliose taken by Di-. Lönnberg are from 

 tlie northern part of the Caspian and Baku. Dr. Lönnberg 

 informs me tliat this alga was rather common on suitable loca- 

 lities, especially at the stations numbered by him 5, 6, 7 and 

 11 and at Baku. The exact locality of these stations and 

 other conditions are mentioned in his paper: »Contributions to 

 the biology of the Caspian Sea», printed in this volume. The 

 depth varied from 13 to 45 feet. He noted the colour of the 

 living specimens to be of that reddish hue which is common 

 among this kind of algge. -) 



^) After this was in the press I received some other specimens of this alga 

 from Prof. Andrussow and apparently from still auother locality. They are 

 also attached to the above mentioned shells and have been coUected by Mr. 

 OsTROUMOw of Kazanam. 



^) Låter investigations since the above was pnt in type have shown that Melo- 

 bettia rnyriocarpa which was hitherto a doubtful species is rather distantly 

 separated from M. casiyica. The latter is, on the other hand, more closely 

 related to Melobeda confervicola (KxJTZ.) Foslie ra. ser., a species from the 

 Adriatic Sea, described long ago, but wrongly iiiterpreted and often mistaken 

 for others. M. caspica and M. confervicola are, nevertheless, so far as the 

 bad material allows the question to be dissolved, specifically distinct. This 

 will, however, be discussed in a separate account on Melobesia in old her- 

 bariums.
