 Corallinaceae 



by M. Foslie — Trondhjem. 



Along the coasts of Asia from the Indian Ocean, eastward to 

 the North Pacific Ocean and farther up to the Bering Sea the 

 tracts have been almost unknown as regards the unarticulated cal- 

 careous Algae, setting aside a few species of Melobesia attached to 

 other Algae, although on the other hand the other groups of Coral- 

 linaceae do not seem to be considerably known. Some species 

 are lately known from the Pacific coast of Japan, but otherwise as 

 far as I know r not a single species has been formerly quoted with 

 any degree of certainty from the said extended coasts. Therefore, 

 every contribution from these tracts may be of importance as 

 regards the knowledge of these up to late times rather neglected 

 Algae and their geographic distribution. 



During the Danish expedition to Siam 1899—1900 some cal- 

 careous Algae were collected in different places in the Gulf of Siam. 

 The collection certainly comprehends but a small number of species 

 which are to be recorded below, giving however some interesting 

 facts as to the distribution of these Algae. The species not formerly 

 described will be pictured on a subsequent occasion. 



Mr. Th. Reinbold of Itzehoe has been kind enough to deter- 

 mine Amphiroa and Corallina.
